Gas test
– setting the shielding gas volume
CAUTION
Electric shocks!
When setting the shielding gas quantity, high voltage ignition pulses or open circuit
voltage are applied at the welding torch; these can lead to electric shocks and burning
on contact.
• Keep the welding torch electrically insulated from persons, animals or equipment during the
setting procedure.
If the shielding gas setting is too low or too high, this can introduce air to the weld pool and may cause
pores to form. Adjust the shielding gas quantity to suit the welding task!
Rule of thumb for the gas flow rate:
Diameter of gas nozzle in mm corresponds to gas flow in l/min.
Example: 7mm gas nozzle corresponds to 7l/min gas flow.
• Press the torch trigger and set the shielding gas quantity with the flow gauge of the pressure regulator.

Arc ignition
5.3.6.1 Liftarc
Figure 5-17
The arc ignites through contact with the workpiece:
a) Carefully place the torch gas nozzle and tungsten electrode tip against the workpiece (lift arc current
flows independent of the set main current)
b) Angle the torch above the torch gas nozzle until the distance between electrode tip and workpiece is
approx. 2
–3 mm (arc ignites, current increases to the set main current).
c) Lift the torch off and bring into normal position.
Complete the welding task: Remove the torch from the workpiece so that the arc extinguishes.

Remote control
The remote controls are operated on the 19-pole remote control connection socket (analogue).
