5.8.4
TIG welding torch, operating variants
The welding process can be controlled with various torch designs
(TT=torch trigger):
In addition to the operating variants described in chaps. 5.8.4.1 and 5.8.4.2, other variants
can be found in the PICOTIG PRO mode operating instructions.
5.8.4.1 Standard TIG torch, 5-pole connector plug (factory setting)
The welding machine is prepared for these torch types as standard.

5.8.4.3 TIG potentiometer torch, 8-pole connection plug
For machines with 8-pole connection sockets (optional), it is not possible to differentiate
between TIG up/down torches and potentiometer torches via the torch detection system
Before commissioning, the welding machine must be converted for the TIG potentiometer
torch.
(see operating instructions for PICOTIG PRO mode, chap. 3.11)
The TIG potentiometer torch can only be used in mode 3.

5.8.5
Tapping operating mode
The tapping mode was included particularly for the secondary current (AMP%) by the use of
a trigger on the welding torch.
Torch with one trigger:
•
by tapping (brief pressing and releasing) torch trigger 1
(Repeated tapping switches back to the main current).
Torch with two triggers:
There are two ways of switching to the secondary current:
•
by tapping (see torch with one trigger)
•
by pressing down and holding torch trigger 2.
