Multi Power 204T
- PILOT ARC WELDING:
The pilot arc can be activated in the following torch trigger procedures:
- 4T LIFT-ARC WELDING
- 4 TIMES + HF WELDING (4T HF)
- 4 TIMES BI-LEVEL + HF WELDING (4T BI-LEVEL HF)
The welding procedure with pilot arc differs with respect to the procedure without pilot arc in the part of
the torch trigger procedure described below.
LIFT-ARC Welding
○ Touch the workpiece with the torch electrode.
○ Press (1T) and keep the torch trigger pressed.
○ Slowly lift the torch to strike the arc.
○ The arc strikes, the welding current assumes the pilot current value.
○ Release (2T) the torch trigger.
○ The welding current reaches the preset value, by way of a up slope time, if programmed.
○ etc.
Welding with HF
○ Press (1T) and keep the torch trigger pressed.
○ The arc strikes without contact with the part and the voltage discharges (HF) cease automatically,
the welding current will assume the pilot current value.
○ Release (2T) the torch trigger.
○ The welding current reaches the preset value, by way of a up slope time, if programmed.
○ etc.
