10. Operation

Checklist
– Check the cable assembly before connecting it to the wire feeding unit to see
whether the wire guide liner is suitable for the wire diameter and wire type.
– Check the equipment in the torch neck, whether the correct contact tip and
torch neck liner is being used for the wire diameter and wire type.
– For liquid-cooled torch models check that the coolant unit is functioning.
Changing wire
– When changing the wire, ensure that the end of the wire is deburred.
– Insert the wire into the wire feeding unit following the operating instructions.
– When inserting the wire, press the wire jog button on the wire feeding unit.
Welding process
Before you begin welding, you must check your protective equipment
and the surrounding area for possible dangers as outlined in
chapter 6.
Make sure that all the parameters required such as metal transfer pro-
cess, wire feed speed, travel feed etc. are set on the control unit for
automated MIG / MAG welding and tailored to the requirements
of your welding task.
For instructions and tips on the welding process itself (technique, materials,
heat...) please consult the relevant literature. This information is not to be
found in these operating instructions.
The torch neck must not be used as a chipping hammer!
Removing from service
When you have finished welding:
1. Wait until the inert gas post-flow time is over.
2. Switch off the power supply.
3. Close the manual-valve for the gas supply.
