Important! Parameters that have been set on one control panel (e.g. wirefeeder or
remote control unit) might not be able to be changed on another control panel (e.g.
power source).
Warning! Operating the equipment incorrectly can cause serious injury and
damage. Do not use the functions described here until you have read and
completely understood all of the following documents:
- these Operating Instructions
- all operating instructions for the system components, especially the "Safety
rules"
Warning! An electric shock can be fatal. If the machine is connected to the
mains electricity supply during installation, there is a high risk of very serious
injury and damage. Only carry out work on the machine when
- the mains switch is in the "O" position,
- the machine is unplugged from the mains.
Connect machine to the mains
Caution! Risk of injury and damage from electric shock and from welding wire
emerging at speed from the torch. When you press the torch trigger:
- hold the torch so that it points away from your face and body
- do not point the welding torch at people
- make sure that the welding wire does not touch any electrically conducting
or earthed (grounded) parts, such as the housing, etc.
Move the mains switch to the "I" position
Note! If the flow of coolant water is insufficient, damage may result. Check the
water flow at regular intervals while the machine is in operation - it must be
possible to see that coolant is flowing properly.
Open the gas-cylinder valve
Set the gas-flow rate:
- Set the gas test mode
- Press the torch trigger
- Turn the adjusting-screw on the underside of the pressure regulator until the
pressure gauge indicates the desired gas flow-rate
