Design and function
MIG/MAG welding
Latched mode
1. cycle
•
Press and hold torch trigger
•
Shielding gas is expelled (gas pre-flows)
•
Wire feed motor runs at "creep speed"
•
Arc ignites when the wire electrode makes contact with the workpiece
Welding current flows
•
Wire feed speed increases to the set nominal value
2. cycle
•
Release torch trigger (no effect)
3. cycle
•
Press torch trigger (no effect)
4. cycle
•
Release torch trigger
•
Wire feed motor stops
•
Arc is extinguished after the pre-selected wire burn-back time elapses
•
Gas post-flow time elapses
