HAVE YOUR INVERTER WELDER REPAIRED BY A QUALIFIED PERSON: The inverter welder is in accordance with the relevant safety requirements. Repairs should only be carried out by qualified persons using original spare parts, otherwise this may result in considerable danger to the user.

• Stop operation immediately if you notice anything abnormal.
• Mount the welder on a secure bench / surface / cart where it is unlikely to slip, move or fall.
• Always disconnect the plug from the mains supply before cleaning or servicing etc.
• Be alert at all times, especially during repetitive, monotonous operations; Don’t be lulled into a false sense of security.
• Use of improper accessories may cause damage to the inverter welder and surrounding area as well as increasing the risk of injury.
• Do not modify the inverter welder to do tasks other than those intended.
• To avoid injury, the workpiece should never be held with bare hands; The workpiece will become hot during normal welding operations, and stay hot for a period after the weld is complete.
• Appropriate personal protective equipment must be worn and must be designed to protect against all hazards created. Severe permanent injury can result from using inappropriate or insufficient protective equipment – Eyes in particular are at risk.
• Always keep a fire extinguisher accessible, close to your welding environment.
• The work should be clamped firmly whilst welding, If its loose it could result in personal injury or damage to the machine or item that is being welded.
• Do not attempt any repairs unless you are a competent electrician or engineer.
• Ensure that the machine is connected to the correct supply voltage and protected by a fuse or circuit breaker of the recommend rating.
• Never allow the earth clamp and electrode holder to come into contact with each other.
• Do not use the welder in any way to thaw frozen pipes.
• Understand the operating environment; Before each use the operator should assess, understand and where possible reduce the specific risks and dangers associated with the operating environment. Bystanders should also be made aware of any risks associated with the operating environment.

ELECTRIC SHOCK

• Keep your body and clothing dry. Never work in a damp area without adequate insulation against electrical shock, stay on a dry duck board, or rubber mat when dampness or sweat can not be avoided. Sweat, sea water or moisture between the body and an electrically ’hot’ part or grounded metal reduces the body surface electrical resistance enabling dangerous and possibly lethal currents to flow through the body.
• Never allow live metal parts to touch bare skin or any wet clothing, be sure welding gloves are dry.
• Before welding, check for continuity; Be sure the earth clamp is connected to the workpiece as close to the welding areas as possible. Grounds connected to building frame work or other remote locations from the welding area reduce efficiency and increase the potential electric shock hazard. Avoid the possibility of the welding current passing through lifting chains, crane cables or various electric paths.
• Frequently inspect leads for wear, splits, cracks and any other damage. Immediately replace those with worn or damaged insulation to avoid a possibly lethal shock from bare leads.

FIRE

• All inflammable materials must be removed from the area.
• Have a suitable fire extinguisher available close by.
• Causes of fire and explosion include; combustibles reached by the arc, flame, flying sparks, hot slag or heated material, misuse of compressed gases and cylinders and short circuits.
• Flying sparks or falling slag can pass through cracks along pipes, through windows or doors and through walls or floor openings and out of sight of the operator. Sparks and slag can fly up to 10 metres.
• Keep equipment clean and operable; Free of oil, grease and of metallic particles (in electrical parts) that can cause short circuits.
• If combustibles are in the area. Do not weld , move the work if practical to an area free of combustibles, avoid paint spray rooms, dip tanks, storage areas and ventilators. If the work can not be moved, then move the combustibles at least 10 metres away and out of the reach of sparks and heat or protect against ignition with suitable and snug fitting, fire resistant covers or shields.
• Walls touching combustibles on opposite sides should not be welded on, walls, ceilings and the floor near the work area should be protected by heat resistant covers or shields.
• Openings (concealed or visible) in floors or walls within 10 metres may expose combustibles to sparks.
• Combustibles adjacent to walls, ceilings, roofs or metal partitions can be ignited by radiant or conducted heat.
• After the work is done, check that the area is free of sparks, glowing embers and flames.
• An empty container that has held combustibles, or that can produce flammable or toxic vapours when heated, must never be welded, unless the container has first been cleaned. Consult HSE INDG214, HSG250 and CS15. HSE document CS15 includes information on cleaning by thorough steam or solvent/caustic cleaning followed by purging and inserting with nitrogen, carbon dioxide or water filling just below working level.
• A container with unknown contents should be treated as if it contained combustibles (see previous paragraph), Do not depend on sense of smell or sight to determine if it is safe to weld.
• Hollow items must be vented before welding as they can explode.
• Explosive atmosphere; Never weld when the air may contain flammable dust, gas or liquid vapours (such as petrol).

GLARE AND BURNS

• The electric welding arc must not be observed with the naked eye. Always use a welding mask; Ensure the welding mask is fitted with the correct shade of filter lens for the welding current level.
• Welding gauntlet gloves should be worn to protect the hands from burns, nonsynthetic overalls with buttons at the neck and wrist, or similar clothing should be worn. Greasy overalls should not be worn. Wear suitable protective footwear.
• Always wear correctly rated protective clothing.
• Avoid oily or greasy clothing, a spark may ignite them.
• Hot metal such as electrode stubs and workpieces should never be handled without gloves.
• First aid facilities and a qualified first aid person should be available for each shift unless medical facilities are close by for immediate treatment of flash burns to the eyes and skin.
• Flammable hair products should not be used by persons intending to weld.
• Warn bystanders not to watch the arc and not to expose themselves to the welding arc rays or to hot metal.
• Keep children away whilst welding, they may not be aware that looking at an arc can cause serious eye damage.
• Protect other nearby personnel from arc rays and hot sparks with a suitable nonflammable partition.
• Ventilation must be adequate to remove the smoke and fumes during welding (see the relevant safety standard for acceptable levels).
• Toxic gases may be given off when welding, especially if zinc or cadmium coated materials are involved, welding should be carried out in a well ventilated area and the operator should always be alert to fume build up.
• Areas with little or no ventilation should always use a fume extractor.
• Vapours of chlorinated solvents can form the toxic gas phosgene when exposed to
• V radiation from an electric arc. All solvents, degreasers and potential sources of these vapours must be removed from the arc area.
• Severe discomfort, illness or death can result from fumes, vapours, heat, oxygen enrichment or depletion that welding (or cutting) may produce. This will be prevented by adequate ventilation or using a fume extractor. Never ventilate with oxygen.
• Lead, cadmium, zinc, mercury, beryllium bearing and similar materials when welded may produce harmful concentrations of toxic fumes. Adequate ventilation must be provided for every person in the area. The operator should also wear an air supplied respirator, for beryllium both must be used.
• Metals coated with or containing materials that emit toxic fumes should not be heated unless coating is removed from the work surface. The area should be well ventilated or the operator should wear an air supplied respirator.
• Work in a confined space only while it is being ventilated and if necessary whilst wearing an air supplied respirator.
• Gas leaks in a confined space should be avoided, leaking gas in large quantities can change oxygen concentration dangerously. Do not bring gas cylinders into a confined space.
• Leaving a confined space you must shut off the gas supply at the source to prevent possible accumulation of gases in the space if down stream valves are left open. Check to be sure that the space is safe before re entering it.
• Vapours from chlorinated solvents can be decomposed by the heat of the arc (or flame) to form phosgene a highly toxic gas and other lung and eye irritating products. The ultra violet (radiant) energy of the arc can also decompose trichloroethylene and perchlorethylene vapours to form phosgene. Do not weld or cut where solvent vapours can be drawn into the welding atmosphere, or where the radiant energy can penetrate to atmospheres containing even minute amounts of trichloroethylene or perchlorethylene.

When using the Inverter welder always ensure the operator as well as those in the area use a welding mask with the correct shade filter lens.
Caution: The warnings and cautions mentioned in this user manual can not cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be applied.

Warning! It is the responsibility of the owner and the operator to read, understand and comply with the following:
You must check all electrical products, before use, to ensure that they are safe.
You must inspect power cables, plugs, sockets and any other connectors for wear or damage.

You must ensure that the risk of electric shock is minimised by the installation of appropriate safety devices; A residual current circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a residual current device (RCD) is used. It is particularly important to use an RCD with portable products that are plugged into a supply which is not protected by an RCCB. If in any doubt consult a qualified electrician.

Connecting to the power supply:

The 05711 SIP Inverter welder is fitted with a standard 230V ~ 13 amp type plug. Before using the Inverter welder, inspect the mains lead and plug to ensure that neither are damaged. If any damage is visible have the welder inspected / repaired by a suitably qualified person. If it is necessary to replace the plug a heavy duty impact resistant plug would be preferable.

The wires for the plug are coloured in the following way:

Yellow / green : Earth
Blue : Neutral
Brown : Live

As the colours of the wires may not correspond with the markings in your plug, proceed as follows: The wire which is coloured blue, must be connected to the terminal
marked with N or coloured black (or blue). The wire which is coloured brown, must be connected to the terminal, which is marked L or coloured red (or brown). The wire which is coloured yellow / green should be connected to the terminal which is coloured the same or marked

Always secure the wires in the plug terminal carefully and tightly. Secure the cable in the cord grip carefully.

This 05715 SIP inverter welder is supplied without a plug fitted, it must not be connected to a 13A supply, consult the technical specification table (page14) for the required rating, if in doubt contact a qualified electrician. Before using the welder, inspect all the leads and plugs to ensure that none are damaged. If any damage is visible have the welder inspected / repaired by a suitably qualified person.

The wires for the plug are coloured in the following way:

Yellow / green : Earth
Blue   :Neutral
Brown : Live

As the colours of the wires may not correspond with the markings in your plug, proceed as follows:
The wire which is coloured brown, must be connected to the terminal, which is marked L or coloured red.
The wire which is coloured blue, must be connected to the terminal marked with N or coloured black.

The wire which is coloured yellow / green should be connected to the terminal which is coloured the same or marked with this symbol

Always secure the wires in the plug terminal carefully and tightly. Secure the cable in the cord grip carefully.

Warning: Never connect live or neutral wires to the earth terminal of the plug.
Only fit an approved plug with the correct rated fuse. If in doubt consult a qualified electrician.
Note: Always make sure the mains supply is of the correct voltage and the correct fuse protection is used. In the event of replacing the fuse always replace the fuse with the same value as the original.
Note: Due to the input current required to run these inverter welders, it is advisable not to use an extension lead. No more than 1 welder should be ran from the same ring main for the same reason.

ARC WELDING
There are no hard and fast rules by which a particular gauge of electrode is selected, usually this is determined by the type of welding required and the thickness of the workpiece e.g. a butt weld in 1.5mm (1/16”) sheet metal can be done by a 1.6mm or 2.0mm electrode, the difference being that the 2.0mm electrode will do the job more quickly.

The table below gives a guide as to which electrode is most suitable according to the material thickness. This table is only a guide, and values given are a indication only.

These welding current values are for the E6013 electrodes, for other types of electrode consult their data sheet.

Electrode Size mm| Material Thickness mm| Welding Current (A)
---|---|---
1.6| 1 – 1.6| 25 – 40
2.0| 1.6 – 2.6| 40 – 70
2.5| 2.6 – 4.0| 60 – 100
3.25| 3.0 – 5.0| 80 – 130
4.0| 5.0 – 7.0| 130 – 170

Note: The above is a guide only; always try a short weld test at the setting selected. It is normal to make minor adjustments to achieve the required weld.
AMPERAGE CONTROL

The welder should be set to a specific amperage to match the electrode size (see above table).
The amperage control is operated by rotating the knob on the front of the welder; Rotate the knob clockwise to increase the amperage and anticlockwise to reduce the amperage. Once the amperage control is set do a short weld and check for correct fusion.

PREPARATION FOR WELDING

• Clean the area to be welded, and the earthing point of all rust, paint and contaminants etc.
• Place the earth clamp on to a cleaned area of the workpiece.
• Connect the welder to the electrical supply but do not switch on.

WELDING

Caution: Ensure all protective equipment is worn and bystanders are not in the vicinity.

• Fit the required electrode securely into the electrode holder.
• Switch the welder on.

Note: Be aware that the electrode is now live, simply touching any part of the workpiece will create a spark.

• Set the welding parameters as previously explained.
• Place a face mask over your face (not supplied).
• Bring the electrode into contact with the workpiece using a light tapping action and withdrawing to create a gap of 1.5 mm – 3.0 mm.
• When the arc is created, proceed steadily in one direction keeping the gap between the electrode and the workpiece constant.
• When the weld is complete simply remove the electrode from the workpiece.
• Remove any excess weld / slag with a wire brush / hammer (not supplied).

Important information: This welder can be set to deliver different output currents at a duty cycle that is written as a percentage on page 14. This percentage represents the welding time in a 10 minute cycle, e.g. 60% means that the welding time is 6 minutes and the rest time is 4 minutes. If a unit is used beyond its duty cycle the temperatures of some components might become too high due to over use; The internal thermal protector will then prevent the unit from operating. Its Intervention is Indicated by the alarm light on the front panel, If this happens leave the machine switched on with the fan running and allow It to cool down. The thermal protector will reset automatically after a short period of time when the components have cooled you will be able to restart welding.

TIG WELDING

You will need to purchase the following items in order to TIG weld (not supplied):

• TIG torch (with gas valve) – SIP Part No. 05029.
• Regulator.
• Tungsten electrode.
• Bottle of argon gas.
• Filler rod.

The required tungsten diameter is determined by the thickness of the material to be welded, for each tungsten size there are strict current limits which should be adhered to. Too great a current causes excessive tungsten consumption and weld pool contamination, whilst too small a current causes arc instability.

The table below gives a guide as to which tungsten is most suitable according to the material thickness. This table is only a guide, and values given are a indication only.

These welding current values are for thorium 2% (red) tungsten electrodes.

Welding Thickness mm| Tungsten Diameter mm| Welding Current Steel| Welding Current Stainless Steel
---|---|---|---
0.5| 1.0| 30-60| 15-30
1.0| 1.6| 50-70| 50-70
1.5| 1.6| 90-110| 60-90
2.0| 1.6| 100-130| 80-100
3.0| 2.4| 120-140| 100-130
4.0| 2.4| 150-190| 130-170

Note: The above is a guide only; always try a short weld test at the setting selected. It is normal to make minor adjustments to achieve the required weld.

PREPARING THE TUNGSTEN

It is important to choose a tungsten with the correct diameter for the current to be used. The tungsten will normally protrude from the ceramic nozzle by 2 or 3mm, in order to gain access to areas such as internal corners the tungsten can be made to protrude by up to 8mm. The tungsten should be sharpened facing the grinding wheel (see right picture). The tip should be perfectly concentric in order to avoid arc deviations. It is best to regularly inspect the tungsten to maintain peak condition.

PREPARATION FOR WELDING

• Clean the area to be welded, and the earthing point of all rust, paint and contaminants etc.
• Connect the earth clamp dinse plug into the positive dinse socket on the welder.
• Place the earth clamp onto a cleaned area of the workpiece.
• Fit the grounded tungsten into the TIG torch head.
• Connect the TIG torch (not supplied) power connector to the negative dinse socket on the welder.
• Connect the regulator (not supplied) onto the gas bottle.
• Connect the TIG torch gas pipe onto the regulator.
• Check the TIG torch gas valve is closed.
• Turn the regulator on.
• Connect the welder to the electrical supply but do not switch on.

WELDING
Caution: Ensure all protective equipment is worn and bystanders are not in the vicinity.

• Switch the welder on.
• Set the welding parameters as previously explained.
• Open the TIG torch gas valve.
• Place a face mask over your face (not supplied).
• Scratch the tungsten on the workpiece, when the arc is created proceed steadily in one direction, maintaining a constant distance between the tip of the tungsten and the workpiece.
• Use a compatible filler rod as required.
• Once all work has been done, switch the machine off and turn the gas off.

Note: This is a DC welder and therefore can not be used for aluminum welding.

MAINTENANCE

• Clear dust from the machine at regular intervals, if used in a dirty environment the machine should be cleaned once a month.
• Check all connections are clean and tight, if there is any oxidization clean the connection with a mild abrasive or wire brush.
• Check all cables for damage or degradation to the insulation, replace if any is found.
• Check electrode holder and earth clamps condition; Ensure they clamp tightly, replace if damaged or loose.
• If the machine is not to be used for a long time, store it in the original packing and in a dry place.
