flow rate
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 conductive or earthed parts (e.g. housing, etc.)
If using a gas-valve torch:

If using welding torch TTG 2200 TCS (TP 2500/3500 TIG only) to set the gas
flow rate:

IMPORTANT! The test gas flow lasts for a maximum of 15 seconds if it is not in-
terrupted by pressing the Process button.

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 weld-
ing current switches off automatically. Place the gas nozzle on the ignition loca-
tion again.

CAUTION!
Move the mains switch to the "I" position
Open the gas cut-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 using the pressure regulator
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 selec-

Select amperage using welding current adjuster
Place the gas nozzle in 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 Gap exists
Gradually tilt up the welding torch until the tungsten electrode touches the
workpiece
