5.3.5 Operating modes (functional sequences)
The welding current operating mode must be set to latched on the welding machine. The welding
current is infinitely adjustable by means of torch triggers 3 and 4 (BRT 3 and BRT 4). Torch trigger
2 (BRT 2) switches the welding current on or off.
Torch trigger 1 (BRT 1) switches the wire feed on or off. The operator can choose between three
operating modes (see following function sequences).
