Latched Mode - EWM L2.00 DC Expert 3.0 TIG Operating Instructions Manual

Functional characteristics
TIG welding
5.1.7.2 Non-latched mode
Sequence
1 st cycle:
• Press and hold torch trigger 1.
• Gas pre-flow time
• HF start pulses jump from the electrode to the workpiece. The arc ignites.
• The welding current flows and immediately assumes the value of the ignition current
• HF switches off.
• The welding current ramps up to the main current
2 nd cycle:
• Release torch trigger 1.
• The main current falls
When the 1 torch trigger is pressed during the down-slope time,
st
the welding current returns to the set main current
• The main current reaches the end-crater current
• the set gas post-flow time
When the foot-operated remote control is connected, the machine switches automatically to non-latched
operation. The up- and down-slopes are switched off.
