•  Burning sensations and irritations in the eyes, nose, and throat are signs of inadequate ventilation. In such a case, immediately boost the ventilation of the work area, and if the problem persists, stop the welding/cutting process completely.
•  Create a natural or artificial ventilation system in the work area.
•  Use a suitable fume extraction system where welding/cutting works are being carried out. If necessary, install a system that can expel fumes and gases accumulated in the entire workshop. Use a suitable filtration system to avoid polluting the environment during discharge.
•  If you are working in narrow and confined spaces or if you are welding lead, beryllium, cadmium, zinc, coated, or painted materials, use masks that provide fresh air in addition to the above precautions.
•  If the gas tanks are grouped in a separate zone, ensure that they are well ventilated, keep the main valves closed when gas cylinders are not in use, pay attention to possible gas leaks.
•  Shielding gases such as argon are denser than air and can be inhaled instead of air if used in confined spaces. This is dangerous for your health as well.
•  Do not perform welding/cutting operations in the presence of chlorinated hydrocarbon vapors released during lubrication or painting operations.
• Some welded / cut parts require special ventilation. The safety rules of products that require special ventilation should be read carefully. A suitable gas mask should be worn when necessary.
Arc Light May Damage
Your Eyes and Skin

| • Use a standard protective mask and a suitable glass filter to protect your eyes and face.
•  Protect other naked parts of your body (arms, neck, ears, etc.) with suitable protective clothing from these rays.
•  Enclose your work area with flame-resistant folding screens and hang warning signs at eye level so that people around you will not sustain injuries from arc rays and hot metals.
•  This machine is not used for heating of icebound pipes. This operation performed with the welding / cutting machine causes explosion, fire or damage to your installation.
Sparks and Spattering Particles May Get Into Eyes and Cause Damage

| •  Performing works such as welding/cutting, surface grinding, and brushing cause sparks and metal particles to splatter. Wear approved protective work goggles which have edge guards under the welding masks to prevent sustaining possible injuries.
Hot Parts May Cause Severe Burns

| •  Do not touch the hot parts with bare hands.
•  Wait until the time required for the machine to cool down before working on its parts.
• If you need to hold hot parts, use suitable tools, welding/cutting gloves with high-level thermal insulation and fire-resistant clothes.
Noise May Cause
Damage To Your
Hearing Ability

| •  The noise generated by some equipment and operations may damage your hearing ability.
•  Wear approved personal ear protective equipment if the noise level is high.
Welding Wires Can
Cause Injuries

| •  Do not point the torch towards any part of the body, other persons, or any metal while unwrapping the welding/ utting wire.
•  When welding wire is run manually from the roller especially in thin diameters the wire can slip out of your hand, like a spring, or can cause damage to you or other people around, therefore you must protect your eyes and face while working on this.
Welding Operations
May Cause Fire and
Explosion

| •  Never perform welding / cutting work in places near flammable materials. There may be fire or
explosions.
•  Before starting the welding / cutting work, remove these materials form the environment or cover
them with protective covers to prevent combustions and flaring.
•  National and international special rules apply in these areas.
•  Do not apply welding/cutting operations into completely closed tanks or pipes.
•  Before welding to tanks and closed containers, open them, completely empty them, and clean them. Pay the greatest attention possible to the welding/cutting operations you will perform in such places.
•  Do not weld in tanks and pipes which might have previously contained substances that may cause explosions, fires, or other reactions.
• Welding/cutting equipment heats up. For this reason, do not place it on surfaces that could easily burn or be damaged !
• Sparks and splashing parts may cause a fire. For this reason, keep materials such as fire extinguishers tubes, water, and sand in easily accessible places.
•  Use holding valves, gas regulators, and valves on flammable, explosive, and compressed gas circuits. Make sure that they are periodically inspected and pay attention that they run reliably.
Maintenance Work
Performed by authorized Persons To Machines and Apparatus May Cause Injuries
| •  Electrical equipment should not be repaired by unauthorized persons.
Errors occurred if failed to do so may result in serious injury or death when using the equipment.

•  It is recommended to perform technical maintenance of the machine and its auxiliary units at least once a year.
Welding/Cutting in
Small Sized and
Confined Spaces

| •  In small-sized and confined spaces, absolutely make sure to perform welding/cutting operations, accompanied by another person.
•  Avoid performing welding/cutting operations in such enclosed areas as much as possible.
Failure To Take
Precautions During
Transport May Cause
Accidents

| •  Take all necessary precautions when moving the machine. The areas where the machine to be transported, parts to be used in transportation and the physical conditions and health of the person carrying out the transportation works should be suitable for the transportation process.
•  Some machines are extremely heavy; therefore, make sure that the necessary environmental safety measures are taken when changing their places.
•  If the machine is to be used on a platform, it must be checked that this platform has suitable load bearing limits.
•  If it is to be transported by means of a haulage vehicle (transport trolley, forklift etc.), make sure of the durableness of the vehicle, and the connection points (carrying suspenders, straps, bolts, nuts, wheels, etc.) that connect the machine to this vehicle.
•  If the machine will be carried manually, make sure the durableness of the machine apparatuses (carrying suspenders, straps, etc.) and connections.
•  Observe the International Labor Organization’s rules on carriage weights and the transport regulations in force in your country in order to ensure the necessary transport conditions.
•  Always use handles or carrying rings when relocating the power-supply sources. Never pull from torches, cables, or hoses. Be absolutely sure to carry gas cylinders separately.
• Remove all interconnections before transporting the welding/cutting equipment, each being separately, lift and transport small ones using its handles, and the big ones from its handling rings or by using appropriate haulage equipment, such as forklifts.
Falling Parts May
Cause Injuries

| Improper positioning of the power-supply sources or other equipment can cause serious injury to persons and physical damage to other objects.
•  Place your machine on the floor and platforms with a maximum tilt of 10° so that it does not fall or tip over. Choose places that do not interfere with the flow of materials, where there is no risk of  tripping over on cables and hoses; yet, large, easily ventilatable, dust-free areas. To prevent gas cylinders from tipping over, on machines with a gas platform suitable for the tanks, fix the tanks on to the platform; in stationary usage applications, fix them to the wall with a chain in a way that they would not tip over for sure.
•  Allow operators to easily access settings and connections on the machine.
Excessive Use Of The Machine Causes
Overheating

| •  Allow the machine to cool down according to operation cycle rates.
• Reduce the current or operation cycle rate before starting the welding / cutting again.
•  Do not block the fronts of air vents of the machines.
•  Do not put filters that do not have manufacturer approvals into the machine’s ventilation ports.
Excessive Use Of The Machine Causes
Overheating

| •  This device is in group 2, class A in EMC tests according to TS EN 55011 standard.
•  This class A device is not intended for use in residential areas where electrical power is supplied from a low-voltage power supply. There may be potential difficulties in providing electromagnetic compatibility due to radio frequency interference transmitted and emitted in such places.
This device is not compliant with IEC 61000 -3-12. In case if it is desired to be connected to the low voltage network used in the home, the installer to make the electrical connection or the person who will use the machine must be aware that the machine has been connected in such a manner; in this case the responsibility belongs to the user.
•  Make sure that the work area complies with electromagnetic compatibility (EMC).
Electromagnetic interferences during welding / cutting operations may cause undesired effects on your electronic devices and network; and the effects of these interferences that may occur during these operations are under the responsibility of the user.
• If there is any interference, to ensure compliance; extra measures may be taken, such as the use of short cables, use of shielded (armored) cables, transportation of the welding machine to another location, removal of cables from the affected device and/or area, use of filters or taking the work area under protection in terms of EMC.
•  To avoid possible EMC damage, make sure to perform your welding / cutting operations as far away from your sensitive electronic devices as possible (100 m).
•  Ensure that your welding and/or cutting machine has been installed and situated in its place according to the user manual.
Evaluation Of
Electromagnetic
Suitability Of The
Work Area

| According to article 5.2 of IEC 60974-9;
Before installing the welding/cutting equipment, the person in charge of the operation and/or the user must conduct an inspection of possible electromagnetic interference in the environment.
Aspects indicated below has to be taken into consideration;
a) Other supply cables, control cables, signal and telephone cables, above and below the welding/cutting machine and its equipment,
b) Radio and television transmitters and receivers,
c) Computer and other control hardware,
d) Critical safety equipment, e.g. protection of industrial equipment,
e) Medical apparatus for people in the vicinity, e.g. pacemakers and hearing aids,
f)  Equipment used for measuring or calibration,
g) Immunity of other equipment in the environment. The user must ensure that the other equipment in use in the environment is compatible. This may require additional protection measures.
h) Considering the time during which the welding/cutting operations or other activities take place during the day, the boundaries of the investigation area can be expanded according to the size of the building, the structure of the building and other activities that are being performed in the building.
In addition to the evaluation of the field, evaluation of device installations may also be necessary for solving the interfering effect. In case if deemed necessary, on-site measurements can also be used to confirm the efficiency of mitigation measures.

Electromagnetic
Interferance
Reduction Methods

| •  The appliance must be connected to the electricity supply in the recommended manner by a competent person. If interference occurs, additional measures may be applied, such as filtering the network. The supply of the fixed-mounted arc welding equipment must be made in a metal tube or with an equivalent shielded cable. The housing of the power supply must be connected and a good electrical contact between these two structures has to be provided.
•  The recommended routine maintenance of the appliance must be carried out. All covers on the body of the machine must be closed and/or locked when the device is in use. Any changes, other than the standard settings without the written approval of the manufacturer, cannot be modified on the appliance. Otherwise, the user is responsible for any consequences that may possibly occur.
• Welding/cutting cables should be kept as short as possible. They must move along the floor of the work area, in a side-by-side manner. Welding/cutting cables should not be wound in any way.
•  A magnetic field is generated on the machine during welding/cutting. This may cause the machine to pull metal parts on to itself. To avoid this attraction, make sure that the metal materials are at a safe distance or fixed. The operator must be insulated from all these interconnected metal materials.
•  In cases where the workpiece cannot be connected to the ground due to electrical safety, or because of its size and position (for example, in building marine vessel bodies or in steel construction manufacturing), a connection between the workpiece and the grounding may reduce emissions in some cases, it should be kept in mind that grounding of the workpiece may cause users to sustain  injuries or other electrical equipment in the environment to break down.
In cases where necessary, the workpiece and the grounding connection can be made as a direct connection, but in some countries where direct connection is not permissible, the connection can be established using  appropriate capacity elements in accordance with local regulations and ordinances.
•  Screening and shielding of other devices and cables in the work area can prevent aliasing effects. Screening of the entire welding/cutting area can be evaluated for some specific applications.
Electromagnetic Field (EMF)

| The electrical current passing through any conductor generates zonal electric and magnetic fields (EMF).
All operators must follow the following procedures to minimize the risk of exposure to EMF;
•  In the name of reducing the magnetic field, the welding / cutting cables must be assembled and secured as far as possible with the joining materials (tape, cable ties etc.).
•  The operator’s body and head should be kept as far away from the welding / cutting machine and cables as possible,

•  In the name of reducing the magnetic field, the welding / cutting cables must be assembled and secured as far as possible with the joining materials (tape, cable ties etc.).
•  The operator’s body and head should be kept as far away from the welding / cutting machine and cables as possible,
• Welding/cutting and electric cables should not be wrapped around the body of the machine in any way,
•  The body of the machine should not get caught between the welding/cutting cables. The source cables must be kept away from the body of the machine, both being placed side by side,
•  The return cable must be connected to the workpiece as close as possible to the work area,
• The welding / cutting machine should not rest against the power unit, ensconce on it and not work too close to it,
• Welding/cutting work should not be performed when carrying the wire supply unit or power unit.
EMF may also disrupt the operation of medical implants (materials placed inside the body), such as pacemakers. Protective measures should be taken for people who carry medical implants. For example, access limitation may be imposed for passers-by, or individual risk assessments may be conducted for welders. Risk assessment should be conducted and recommendations should be made by a medical professional for users who carry medical implants.
Protection

| • Do not expose the machine to rain, prevent the machine from splashing water or pressurized steam.
Energy Efficiency

| •  Choose the welding/cutting method and welding machine for the welding work you are to perform.
•  Select the welding / cutting current and/or voltage to match the material and thickness you are going to weld.
•  If you have to wait for a long time before you start your welding / cutting work, turn off the machine after the fan has cooled it down. Our machines with smart fan control will turn off on their own.
Waste Procedure

**| •  This device is not domestic waste. It must be directed to recycling within the framework of the European Union directive and national laws.
•  Obtain information from your dealer and authorized persons about the waste management of your used machines.

• If the CO2 heater will not be used, connect the gas regulator directly to the gas cylinder.
• Connect one end of the tube hose to the gas regulator and tighten the clamp. Connect the other end to the gas inlet at the back of the machine and tighten the nut.
• Open the gas cylinder valve to check that the tube is full and that there are no leaks in the gas flow path. If you hear a noise and/or detect a smell of gas as a leak indicator, examine your connections and eliminate leakage.

OPERATION

Connection to Mains

When plugging the power plug into the outlet, make sure that the power switch is set to “0”.

• Check the 3-phase with a voltmeter before connecting the machine to the mains. After detecting that each phase is 400V (± 40V), attach the plug into the wall outlet.
• Start the machine with the on/off switch.
• Turn the machine off by turning the switch back to the “0” position after hearing the fan sound and seeing the ammeter and voltmeter lights are on.

Preparation and Connection of the Torch

• Use the torch according to the capacity of your machine and the welding you will perform.

• Make sure that the diameters of the spiral and contact nozzle inside the torch match the diameter of the welding wire you will use. Replace the spiral and contact nozzle if necessary.

• To change the spiral, remove the nozzle, contact nozzle, and adapter respectively.

• Afterwards, remove the spiral nut on the torch connector side with a wrench and extend the torch so that it is in flat position and remove the spiral inside the torch.

• After inserting the new spiral into the torch, install and firmly tighten the spiral nut.

• Cut the excess of the spiral from the torch head with a side chisel at the point where the gas distributor (contact nozzle holder) immediately ends as shown on the right, so that there is no gap between the spiral and the contact nozzle. File the cut point to make it blunt and burr free.

• Connect the torch to the torch connector and tighten the nut firmly.

Selection and Replacement of Wire Feed Rollers

• Open the cover of the wire feed part. You will see the four-roller wire feed system.
  1- Engine
  2- Euro Connector
  3- Pressure Roller Handle| 4- Pressure Rollers
  5- Wire Feed Rollers
  6- WF Roller Screws
  ---|---
• Use wire feed rollers suitable for the material and diameter of the welding wire you will use. Use V-grooved wire feed rollers for steel and stainless steel, corrugated V-grooves for cored wires, and U corrugated ones for aluminum.

If you need to replace the wire feed rollers, pull the pressure roller lever toward your side and after lifting the pressure rollers, remove the wire feed roller screws and remove the existing rollers.

Both sides of the rollers are marked according to the wire diameter used. Place the rollers on the flange so that the wire diameter value you will use will be on the side facing your side.

• After inserting the rollers, you will use, re-insert the screws and lower the pressure rollers and lock the pressure roller lever onto the rollers.

Placing the Wire Spool and Wire Feeding Process

• Unscrew the screw of the wire transport system by turning it. Insert the welding wire roller parallel to the wire ground and always from the bottom to the wire transport system shaft and re-tighten the screw.

Over-tightening the nut will prevent the wire from feeding and may cause failures. Under-tightening of the nut may cause the roller to be released at the time wire feed is stopped and mixed after a while. For this reason, do not connect the nut too tightly or too loosely.

• Pull and lower the pressure lever on the wire feed rollers, which means bring the pressure rollers to idle position.
• Remove the welding wire from the point where the roller is connected and cut off the end with a side chisel.

If the end of the wire is missed, the wire can jump like a spring and damage you and others.

• Pass the wire through the wire entry slot without releasing the wire into the rollers and into the torch through the rollers.

• Press the pressure rollers and lift the pressure lever 1.

• Turn the on/off switch to position “1” to start the machine 2.

• Press the trigger until the wire comes out from the tip of the torch, while observing that the welding wire roller rotates freely then push and release the trigger a few times to check for any loosening of the winding 3.

• If loosening and/or backwinding is observed, tighten the screw of the wire bearing system.

• Re-attach the nozzle and contact nozzle to the torch when the wire comes out from the tip of the torch 4.

• Drive the wire on a 5 board and make the appropriate 6 wire pressure adjustment and cut the tip of the wire 7.

A: Suitable wire pressure and conduit dimensions
B: The wire is distorted since the pressure lever is too tight.
C: The roller surface is deteriorated due to excessive pressure on the pressure lever.
D: The conduit length of the roller is small for the wire used. The shape of the wire is distorted.
E: The conduit length of the roller is big for the wire used. The wire cannot be transmitted to the welding area.

Adjustment of Gas Flow

Make the gas adjustment and gas test by lifting the wire feed roller pressure lever!

• Adjust the gas flow with the flow control valve.
• Practical gas flow rate (CO, Ar, mixture) is 10 times of wire diameter. For example, if the wire diameter is 0.9 mm, the gas flow rate can be adjusted as 10 x 0.9 = 9 l/min.
• You can use the table on the side for more precise flow adjustment.
• After adjusting the gas flow, lift the thrust bearing arm and close the wire feed unit door.

| | Mild Steel and
Metal Cored| Flux Cored| Stainless Steel| Aluminium
---|---|---|---|---|---
Diameter (mm)| 0.8| 8 lt/min| 7 lt/min| 8 lt/min| 8 lt/min
0.9| 9 lt/min| 8 lt/min| 9 lt/min| 9 lt/min
1| 10 lt/min| 9 lt/min| 10 lt/min| 10 lt/min
1.2| 12 lt/min| 11 lt/min| 12 lt/min| 12 lt/min
1.6| 16 lt/min| 15 lt/min| 16 lt/min| 16 lt/min

Note: Recommended values in standard conditions.

Using Trigger Modes

• The trigger mode switch selects 2-position, 4-position or pnt position.
• The 2-position operates as shown in Figure 15.
• The 4-position operates as shown in Figure 16. The 4-position provides ease of use for the welder in long-term and automatic welding operations.
• In the pnt mode, the welding starts at the moment the trigger is pressed, the welding continues until the set time period is on and stands by as long as the off-time period. The process continues in this manner until the trigger is released and the welding stops as soon as the trigger is released.

Starting and Ending the Welding Process

• Determine the Coarse Adjustment “, Fine Adjustment” and Wire Feed Speed from the welding parameters table of your machine according to the diameter of the wire you will use, the type of gas you will use and the thickness of the material to be welded, and set your machine to these settings.

| Wire Diameter
