Contact Ignition
for Welding Torch
without Torch
Trigger
When the setup parameter "IGn" is set to "oFF", the HF ignition is deactivated. The arc ig-
nites when the workpiece makes contact with the tungsten electrode.
The setup parameter "Tri" must be set to "oFF".
Procedure for igniting the arc using contact ignition for welding torches without torch trig-
ger:
Position the gas nozzle at the ignition
point so that there is a distance of ap-
proximately 2 to 3 mm (5/64 to 1/8 in.)
between the tungsten electrode and
the workpiece
Actuate gas cut-off valve
Shielding gas flows
Gradually tilt the welding torch up until
the tungsten electrode touches the
workpiece
Raise the welding torch and rotate it
into its normal position
The arc ignites.
Carry out welding
