Important! As long as the torch is touching the workpiece, the gas pre-flow takes place
automatically. If the torch and workpiece remain in contact for more than 3 seconds, the
welding current switches off automatically. Place the gas nozzle on the ignition location
again.

CAUTION! Risk of injury and damage from electric shock. As soon as the
mains switch is in the "I" position, the tungsten electrode of the welding torch
is LIVE. Make sure that the tungsten electrode does not touch any persons or
electrically conducting or earthed parts (e.g. housing etc.)
Move the mains switch to the "I" position
Open the gas shut-off valve on the torch or press the torch trigger and set the
desired gas flow rate at the pressure regulator
Move the mains switch to the „O" position
Press the process button and simultaneously move the mains switch to the „I"
position
- All indicators on the control panel flash
- The fan switches on
- The gas solenoid valve picks up
Set the desired shielding gas flow rate at the pressure controller
Press the process button
- The indicators on the control panel stop flashing
- The fan switches off (if the temperature allows)
- The gas solenoid valve drops out
Select one of the following processes using the process button:
The following indicator lights up if the TIG welding process is selected:
The following indicator lights up if the TIG pulsed arc process is selected:
Select current using welding current adjuster
Place the gas nozzle on the ignition location so that there is a gap of 2 - 3 mm (0.08
- 0.12 in.) between the tungsten tip and the workpiece
Gradually tilt up the welding torch until the tungsten tip touches the workpiece
Raise the torch and pivot it into the normal position - the arc ignites
Start welding
