SAFETY INSTRUCTION
Use of Personal Protective Equipment (PPE) Welding arc rays from all welding
processes produce intense, visible and invisible (ultraviolet and infrared)
rays that can burn eyes and skin. · Wear an approved welding helmet fitted
with an appropriate shade of
filter lens to protect your face and eyes when welding or watching. · Wear
approved safety glasses with side shields under your helmet. · Never use
broken or faulty welding helmets. · Always ensure there are adequate
protective screens or barriers to
protect others from flash, glare and sparks from the welding area. · Ensure
that there are adequate warnings that welding or cutting is
taking place. · Wear suitable protective flame resistant clothing, gloves and
footwear. · Check and be sure the area is safe and clear of inflammable
material
before carrying out any welding. Some welding and cutting operations may
produce noise. Wear safety ear protection to protect your hearing if the
ambient noise level exceeds the local allowable limit (e.g: 85 dB). Welding

SAFETY INSTRUCTION
Safety against fumes and welding gases
The HSE have identified welders as being an at risk’ group for occupational diseases arising from exposure to dusts, gases, vapours and welding fumes. The main identified health effects are pneumonia, asthma, chronic obstructive pulmonary disease (COPD), lung and kidney cancer, metal fume fever (MFF) and lung function changes. During welding and hot cuttinghot work’ operations,
fumes are produced which are collectively known as welding fume. Depending
upon the type of welding process being performed, the resultant fume generated
is a complex and highly variable mixture of gases and particulates. Regardless
of the length of welding being carried out, all welding fume, including mild
steel welding requires suitable engineering controls to be in place which is
usually Local Exhaust Ventilation (LEV) extraction to reduce the exposure to
welding fume indoors and where LEV does not adequately control exposure it
should also be enhanced by using suitable respiratory protective equipment
(RPE) to assist with protecting against residual fume. When welding outdoors
appropriate RPE should be used.
Prior to undertaking any welding tasks an appropriate risk
assessment should be carried out to ensure expected control
measures are in place.
An example of personal fume protection
Locate the equipment in a well-ventilated position and keep
your head out of the welding fume.
Do not breathe the welding fume.
Ensure the welding zone is well-ventilated and provision should be made for suitable local fume
extraction system to be in place.
If ventilation is poor, wear an approved airfed welding helmet or respirator.
Read and understand the Material Safety Data Sheets (MSDS’s) and the manufacturer’s instructions for
metals, consumable, coatings, cleaners and de-greasers.
Do not weld in locations near any de-greasing, cleaning or spraying operations.
Be aware that heat and rays of the arc can react with vapours to form highly toxic and irritating gases.
For further information please refer to the HSE website www.hse.gov.uk for related documentation.
Precautions against fire and explosion
Avoid causing fires due to sparks and hot waste or molten metal. Ensure that
appropriate fire safety devices are available near the welding and cutting
area. Remove all flammable and combustible materials from the welding, cutting
and surrounding areas. Do not weld or cut fuel and lubricant containers, even
if empty. These must be carefully cleaned before they can be welded or cut.
Always allow the welded or cut material to cool before touching it or placing
it in contact with combustible or flammable material. Do not work in
atmospheres with high concentrations of combustible fumes, flammable gases and
dust. Always check the work area half an hour after cutting to make sure that
no fires have begun. Take care to avoid accidental contact of electrode to
metal objects. This could cause arcs, explosion, overheating or fire.
Understand your fire extinguishers
6
SAFETY INSTRUCTION
The Working environment Ensure the machine is mounted in a safe and stable
position allowing for cooling air circulation. Do not operate equipment in an
environment outside the laid down operating parameters. The welding power
source is not suitable for use in rain or snow. Always store the machine in a
clean, dry space. Ensure the equipment is kept clean from dust build up.
Always use the machine in an upright position.
Protection from moving parts When the machine is in operation keep away from
moving parts such as motors and fans. Moving parts, such as the fan, may cut
fingers and hands and snag garments. Protections and coverings may be removed
for maintenance and controls only by qualified personnel after first
disconnecting the power supply cable. Replace the coverings and protections
and close all doors when the intervention is finished and before starting the
equipment. Take care to avoid getting fingers trapped when loading and feeding
wire during set up and operation. When feeding wire be careful to avoid
pointing it at other people or towards your body. Always ensure machine covers
and protective devices are in operation.
Risks due to magnetic fields The magnetic fields created by high currents may
affect the operation of pacemakers or electronically controlled medical
equipment. Wearers of vital electronic equipment should consult their
physician before beginning any arc welding, cutting, gouging or spot welding
operations.
Do not go near welding equipment with any sensitive electronic equipment as
the magnetic fields may cause damage. Keep the torch cable and work return
cable as close to each other as possible throughout their length. This can
help minimise your exposure to harmful magnetic fields. Do not wrap the cables
around the body.
Handling of compressed gas cylinders and regulators Mishandling gas cylinders
can lead to rupture and the release of high pressure gas. Always check the gas
cylinder is the correct type for the welding to be carried out. Always store
and use cylinders in an upright and secure position. All cylinders and
pressure regulators used in welding operations should be handled with care.
Never allow the electrode, electrode holder or any other electrically “hot”
parts to touch a cylinder. Keep your head and face away from the cylinder
valve outlet when opening the cylinder valve. Always secure the cylinder
safely and never move with regulator and hoses connected. Use a suitable
trolley for moving cylinders. Regularly check all connections and joints for
leaks. Full and empty cylinders should be stored separately.
Never deface or alter any cylinder

SAFETY INSTRUCTION
RF Declaration Equipment that complies with directive 2014/30/EU concerning
electromagnetic compatibility (EMC) and the technical requirements of
EN60974-10 is designed for use in industrial buildings and not those for
domestic use where electricity is provided via the low voltage public
distribution system. Difficulties may arise in assuring class A
electromagnetic compatibility for systems installed in domestic locations due
to conducted and radiated emissions. In the case of electromagnetic problems,
it is the responsibility of the user to resolve the situation. It may be
necessary to shield the equipment and fit suitable filters on the mains
supply.
LF Declaration Consult the data plate on the equipment for the power supply
requirements. Due to the elevated absorbance of the primary current from the
power supply network, high power systems affect the quality of power provided
by the network. Consequently, connection restrictions or maximum impedance
requirements permitted by the network at the public network connection point
must be applied to these systems. In this case, the installer or the user is
responsible for ensuring the equipment can be connected, consulting the
electricity provider if necessary.
Materials and their disposal Welding equipment is manufactured with BSI
published standards meeting CE requirements materials which do not contain any
toxic or poisonous materials dangerous to the operator. Do not dispose of the
equipment with normal waste. The European Directive 2012/19/EU on Waste
Electrical and Electronic Equipment states the electrical equipment that has
reached its end of life must be collected separately and returned to an
environmentally compatible recycling facility for disposal. For more detailed
information please refer to the HSE website www.hse.gov.uk

OPERATION – MMA
Before starting any welding activity ensure that you have suitable eye
protection and protective clothing. Also take the necessary steps to protect
any persons within the welding area.
MMA welding mode
MMA (Manual Metal Arc), SMAW (Shielded Metal Arc Welding) or just Stick
Welding. Stick welding is an arc welding process which melts and joins metals
by heating them with an arc between a covered metal electrode and the work.
Shielding is obtained from the electrode outer coating, often called flux.
Filler metal is primarily obtained from the electrode core.
The electrodes outer coating called flux assists in creating the arc and
provides a shielding gas and on cooling forms a slag covering to protect the
weld from contamination.
When the electrode is moved along the work piece at the correct speed the
metal core deposits a uniformed layer called the weld bead.
After connecting the welding leads as detailed you will need to switch the
power switch on the back panel to “ON”.
Select the MIG/MMA by switching to the MMA welding mode. There is now open
circuit voltage output at both output terminals.
Ensure you check that you have the electrode polarity correct.
Set the amperage on the machine suitable for the electrode being used.
Please see a guide to amperages required, although this MMA welding electrode
guide can vary depending on material, work piece thickness, welding position
and joint form.

MIG/MAG welding mode
MIG – Metal Inert Gas Welding, MAG – Metal Active Gas Welding, GMAW – Gas
Metal Arc Welding
MIG welding was developed to help meet production demands of the war and post
war economy which is an arc welding process in which a continuous solid wire
electrode is fed through a MIG welding gun and into the weld pool, joining the
two base materials together.
A shielding gas is also sent through the MIG welding gun and protects the weld
pool from contamination which also enhances the arc.
Connect the MIG torch leads as detailed on page 12. B Work return lead to -‘ (B) and torch trailing lead to+’ (A).
Ensure that a suitable inert gas supply is connected. A Switch the power
switch on the back panel to “ON” the machine is started with the power LED on
and the fans are running.
Switch the MMA/MIG switch to MIG mode (ensuring the standard/spool gun switch
is set to standard).
Open the gas valve of the cylinder and adjust the gas regulator to obtain the
desired flow rate.
Adjust the “voltage control knob in MIG” and “wire feed speed control knob in
MIG” on the front panel of the machine to get the correct welding voltage and
welding current.
Operate the torch trigger and welding can be carried out.
Where required adjust the burn-back time potentiometer (above the feed unit
inside the machine) to get the proper wire stick-out. One second after the arc
stops, the gas supply will be cut off.

GUIDE TO MMA WELDING
Before starting any welding activity ensure that you have suitable eye
protection and protective clothing. Also take the necessary steps to protect
any persons within the welding area.
Notes for the welding beginner This section is designed to give the beginner
who has not yet done any welding some information to get them going. The
simplest way to start is to practice by running weld beads on a piece of scrap
plate. Start by using mild steel (paint free) plate of 6.0mm thick and using
3.2mm electrodes. Clean any grease, oil and loose scale from the plate and fix
firmly to your work bench so that welding can be carried out. Make sure that
the work return clamp is secure and making good electrical contact with the
mild steel plate, either directly or through the work table. For best results
always clamp the work lead directly to the material being welding, otherwise a
poor electrical circuit may create itself.
Welding position When welding, ensure you place yourself in a comfortable
position for welding and your welding application before you begin to weld.
This maybe by sitting at a suitable height which often is the best way to weld
ensuring you’re relaxed and not tense. A relaxed posture will ensure the
welding task becomes much easier. Please ensure you always wear suitable PPE
and use suitable fume extraction when welding. Place the work so that the
direction of welding is across, rather than to or from your body. The
electrode holder lead should always be clear of any obstruction so that you
can move your arm freely along as the electrode burns down. Some elders prefer
to have the welding lead over their shoulder, this allows greater freedom of
movement and can reduce the weight from your hand. Always inspect your welding
equipment, welding cables and electrode holder before each use to ensure it is
not faulty or worn as you may be at risk of an electric shock.
MMA process features and benefits The versatility of the process and the skill
level required to learn, basic simplicity of the equipment make the MMA
process one of the most common used throughout the world.
The MMA process can be used to weld a wide variety of materials and is
normally used in the horizontal position but can be used in vertical or
overhead with the correct selection of electrode and current. In addition, it
can be used to weld at long distances from the power source subject to the
correct cable sizing. The self shielding effect of the electrode coating makes
the process suitable for welding in external environments. It is the dominant
process used in maintenance and repair industries and is used extensively in
structural and fabrication work. The process is well able to cope with less
than ideal material conditions such as dirty or rusty material. Disadvantages
of the process are the short welds, slag removal and stop starts which lead to
poor weld efficiency which is in the region of 25%. The weld quality is also
highly dependent on the skill of the operator and many welding problems can
exist.
17
GUIDE TO MMA WELDING
Before starting any welding activity ensure that you have suitable eye
protection and protective clothing. Also take the necessary steps to protect
any persons within the welding area. MMA process tips and guides Typical
welder set up 1. Electrode holder 2. Work return clamp 3. Work piece 4. Weld
material covered by electrode flux or slag 5. Electrode 6. Distance from work
to electrode (arc Length)
Welding current will flow in the circuit as soon as the electrode contacts the
work piece. The welder should always ensure a good connection of the work
clamp. The nearer the clamp is placed to the welding area the better. When the
arc is struck the distance between the end of the electrode and the work will
determine the arc voltage and also affect the weld characteristic. As a guide
the arc length for electrodes up to 3.2mm diameter should be around 1.6mm and
over 3.2mm around 3mm. Upon completion of the weld the welding flux or slag
will need to be removed usually with a chipping hammer and wire brush.
Joint form in MMA In MMA welding, the common basic joint forms: butt joint,
corner joint, lap joint & T joint.

GUIDE TO MMA WELDING
Before starting any welding activity ensure that you have suitable eye
protection and protective clothing. Also take the necessary steps to protect
any persons within the welding area. MMA arc striking Tap technique – Lift the
electrode upright and bring it down to strike the work piece. After forming
short circuit, quickly lift up about 2~4mm and arc will be ignited. This
method is difficult to master.
Scratch technique – Drag the electrode and scratch the work piece as if
striking a match. Scratching the electrode may cause the arc to burn along the
scratch path, so care should be taken to scratch in the weld zone. When the
arc is struck adopt the correct welding position.
Electrode positioning Horizontal or flat position The electrode should be
positioned at right angles to the plate and inclined in the direction of
travel at around 10º-30º.

GUIDE TO MMA WELDING
Before starting any welding activity ensure that you have suitable eye
protection and protective clothing. Also take the necessary steps to protect
any persons within the welding area. Fillet welding The electrode should be
positioned to split the angle i.e. 45º. Again the electrode should be inclined
in the direction of travel at around 10º-30º.
Manipulation of electrode In MMA welding there are three motions used at the
end of electrode: 1. The electrode feeding to the
molten pool along axis 2. The electrode swing right and left 3. The electrode
moving in the weld
direction
The operator can choose the manipulation of electrode based on welding joint,
welding position, electrode spec, welding current and operation skill etc.
Weld characteristics A good weld bead should exhibit the following
characteristics:
1. Uniform weld bead 2. Good penetration into the base material 3. No overlap
4. Fine spatter level A poor weld bead should exhibit the following
characteristics: 1. Uneven and erratic bead 2. Poor penetration into the base
material 3. Bad overlap 4. Excessive spatter levels 5. Weld crater

Before starting any welding activity ensure that you have suitable eye
protection and protective clothing. Also take the necessary steps to protect
any persons within the welding area.
Notes for the welding beginner This section is designed to give the beginner
who has not yet done any welding some information to get them going. The
simplest way to start is to practice by running weld beads on a piece of scrap
plate. Start by using mild steel (paint free) plate of 6.0mm thick and using
0.8mm wire. Clean any grease, oil and loose scale from the plate and fix
firmly to your work bench so that welding can be carried out . Make sure that
the work return clamp is secure and making good electrical contact with the
mild steel plate, either directly or through the work table. For best results
always clamp the work lead directly to the material being welding, otherwise a
poor electrical circuit may create itself.
MIG/MAG process features and benefits Terms used: MIG – Metal Inert Gas
Welding
MAG – Metal Active Gas Welding GMAW – Gas Metal Arc Welding
MIG welding was developed to help meet production demands of the war and post
war economy which is an arc welding process in which a continuous solid wire
electrode is fed through a MIG welding gun and into the weld pool, joining the
two base materials together. A shielding gas is also sent through the MIG
welding gun and protects the weld pool from contamination which also enhances
the arc.
The MIG/MAG process can be used to weld a wide variety of materials and is
normally used in the horizontal position but can be used in vertical or
overhead with the correct selection of machine, wires and current. In
addition, it can be used to weld at long distances from the power source
subject to the correct cable sizing. It is the dominant process used in
maintenance and repair industries and is used extensively in structural and
fabrication work. Weld quality is also highly dependent on the skill of the
operator and many welding problems can exist due to incorrect installation
application and use.
Welding position When welding, ensure you place yourself in a comfortable
position for welding and your welding application before you begin to weld.
This maybe by sitting at a suitable height which often is the best way to weld
ensuring you’re relaxed and not tense. A relaxed posture will ensure the
welding task becomes much easier. Please ensure you always wear suitable PPE
and use suitable fume extraction when welding. Place the work so that the
direction of welding is across, rather than to or from your body. The
electrode holder lead should always be clear of any obstruction so that you
can move your arm freely along as the electrode burns down. Some elders prefer
to have the welding lead over their shoulder, this allows greater freedom of
movement and can reduce the weight from your hand. Always inspect your welding
equipment, welding cables and electrode holder before each use to ensure it is
not faulty or worn as you may be at risk of an electric shock.

MIG process description
The MIG process was first patented for the welding of aluminium in 1949 in the
USA. The process uses the heat that is generated by an electric arc formed
between a bare consumable wire electrode and the work piece. This arc is
shielded by a gas to prevent oxidation of the weld.
In the MIG process an inert shielding gas is used to protect the electrode and
weld pool from contamination and enhance the arc. Originally this gas was
helium.
In the early 1950’s the process became popular in the UK for welding aluminium
using argon as the shielding gas. Development in the use of different gases
resulted in the MAG process. This is where other gases were used, for example,
carbon dioxide and sometimes users refer to this process as CO² welding. Gases
such as oxygen and carbon dioxide were added and are active constituents to
the inert gas to improve the welding performance. Although the MAG process is
in common use today it is still referred to as MIG welding although
technically this is not correct. The process began to prove itself as an
alternative to stick electrode (MMA) and TIG (GTAW) offering high productivity
and deposition rates. The process also helps reduce any weld defects from the
increased stop/starts used in MMA. However, the welder must have a good
knowledge of the system set up and maintenance to achieve satisfactory welds.
The electrode MIG gun is normally +VE and the work return is normally VE.
However, certain consumable wires sometimes require what is called reverse
polarity i.e. Electrode VE or work +VE. Typical of these types of wire are
cored wires used in hard facing or high deposition and gasless applications.

MIG controls
The main basic controls for the MIG/MAG system are as follows. Controls can be
electro mechanical or electronic but the effects will be the same.
Wire feed speed
The wire speed is directly related to the current. The higher the wire speed
the more wire is deposited and hence more current is required to burn off the
consumable wire. Wire speed is measured in m/min (metres per min) or sometimes
in ipm (inches per minute). The diameter of the wire also forms part of the
current demand e.g. a 1.0mm wire feeding at 3m per min will require less
current than a 1.2mm wire feeding at the same rate. The wire feed is set
according to the material to be welded. If the wire feed rate is too high in
comparison to the voltage then a “stubbing” effect happens where unmelted
consumable contacts the work piece creating large amounts of weld spatter. Too
little wire feed comparison to the voltage will result in a long arc being
created with poor transfer and eventual burning back of the wire onto the
contact tip.
Voltage Wire Speed Voltage setting
The voltage polarity in MIG/MAG welding is in the majority of cases with the
positive (+). This means that the majority of the heat is in the electrode
wire. Certain special wires may require the polarity to be reversed i.e.
electrode wire negative (-) polarity. Always consult the manufacturer’s data
sheet for the best operating parameters. The voltage is often referred to as
the “heat setting”. This will be altered dependent on the material type,
thickness, gas type, joint type and position of the weld. Combined with the
wire speed it is the main control adjusted by the welder. The voltage setting
varies depending on the type and size of electrode wire being used. Most
MIG/MAG welders are CV or Constant Voltage power sources which means the
voltage does not vary much during welding. Modern inverter power sources also
have control circuits to monitor conditions to ensure voltage remains
constant. The voltage determines height and width of the weld bead. If the
operator has no reference to settings required the best method of set up is to
use scrap material of the same thickness to obtain the correct setting. If
there is too much voltage the arc will be long and uncontrollable and cause
the wire to fuse to the contact tip. If the voltage is too low then there will
not be enough heat to melt the wire and then stubbing occurs. To obtain a
satisfactory weld a balance needs to be made between voltage and wire speed.
Characteristics of the voltage are that the higher voltage produces a flatter
and wider weld bead but care must be taken to avoid undercut. The lower the
voltage the weld bead becomes narrow and higher.
24
GUIDE TO MIG/MAG WELDING
Before starting any welding activity ensure that you have suitable eye
protection and protective clothing. Also take the necessary steps to protect
any persons within the welding area. Burn back control In the event that the
welder was to stop welding and all functions of the machine stopped
simultaneously then the consumable filler wire would in all likelihood freeze
in the weld pool. In order to avoid this happening the burn back feature is
present on this machine. This facility is an adjustable control within these
Jasic compact MIG machines and it will allow the power and gas shield to be
maintained on the consumable filler wire when it has stopped feeding thereby
burning clear of the weld.
Some quick reference handy tips for the MIG/MAG welding process are: · When
welding, try to use an electrode stick out (the distance between the weld and
the contact tip)
of around 6-8mm. · When welding thin materials try and use smaller MIG wire
diameters and for thicker materials use
thicker wires. · Make sure you select the correct MIG wire type for the
material to be welded. · Ensure the MIG welding gun has the correct sized
contact tip and type of liner. · Always ensure you have the correct size drive
rolls and torch liner for the wire size selected. · Select the correct gas to
achieve the correct weld characteristics and finish. · For optimum control of
the weld keep the wire at the leading edge of the weld pool. · Before
commencing welding, ensure a comfortable and stable position. · Try to keep
the welding torch as straight as possible when welding to ensure the best
feed. · Carry out daily housekeeping on the condition of the welding torch and
drive rolls. · Keep any consumables clean and dry to avoid contamination such
as oxidation and damp.
