4.1
Preparing the welding torch for installation of the cable assembly
1 Switch off the power source and unplug the power plug.
4.2
Equipping the torch neck
The MIG/MAG manual welding torches are fully equipped upon delivery.
Information about replacing wear parts and about the wire guide can be
found here:
4.3
Connecting the cable assembly, fig. A
1 At the wire feeder: insert the central plug in the connecting socket.
2 At the wire feeder: secure the cable assembly with the connection nut.
3 Coolant: connect the flow line (blue) and return line (red).
• Check the coolant's minimum fill level.
4.4
Purging the coolant circuit, fig. B
1 Place the collection receptacle below the coolant return connector (red).
2 Loosen the coolant return hose at the coolant recirculator and hold it over
a collection receptacle.
4.5
Connecting the shielding gas
• Select the appropriate shielding gas for the welding task at hand.
• Briefly open the gas supply valve and close it again to blow out any
contamination at the connector.
4.6
Feed in wire
CAUTION
Risk of injury
Puncture or cut-in wounds may be caused by the wire electrode.
• Keep your hands out of the danger zone and wear the correct protective gloves.
1 Cut off a small piece of the start of the wire with a cutter to remove
any burrs.
2 Insert the wire in the wire feeder according to the manufacturer's
instructions.

Operational controls on the handle
NOTICE
• Consult the documentation for the welding components.
The button's two-cycle operating mode is available for the standard welding
torch.
5.1
Button with two-cycle function, fig. C
1 Press and hold button on handle = start welding.
6
Operation
1 Open the shielding gas cylinder, switch on the power source.
2 Set the welding parameters
7
Decommissioning
NOTICE
• Liquid-cooled cable assemblies leak if overheated. Therefore, allow the cooling unit to continue to run approximately 5 minutes after welding.
1 End welding.
2 Wait until the shielding gas post-flow time has passed and switch off the
power supply.
3 Close the shielding gas cylinder valve.
5 Operational controls on the handle
2 Switch off the gas and compressed air connector.
8 Maintenance and cleaning on page EN-36
• Recommendation: use ABICOR BINZEL BTC coolant.
• To prevent damage to the welding machine, do not use deionized or
demineralized water.
• Purge the coolant circuit the first time the equipment is commissioned and
with every cable assembly replacement.
3 Seal the opening on the coolant return hose. Open and close it multiple
times. Repeat this process until the coolant flows into the collection
receptacle continuously and without air bubbles.
4 Re-connect the return hose to the coolant recirculator.
• Connect the shielding gas to the welding device according to the
manufacturer's instructions.
• Adjust and set the amount of shielding gas for the gas nozzle in use and
welding task at hand.
3 Press the button to switch off power to the wire feeder until the wire exits
the contact tip.
4 Cut off any protruding wire.
Additional operating modes and handle modules depend on the power
source and must be purchased separately.
2 Release the button = end welding.
3 Start welding.
