Step 1:
• Press and hold torch trigger
• Shielding gas is expelled (gas pre-flows)
• Wire feed motor runs at “creep speed”.
• Arc ignites after the wire electrode makes contact with the workpiece; welding current flows.
• Start the super pulse function beginning with main program P
A
.
The welding parameters change at the specified times between main program P
A
and the reduced
main program P
B
.
Step 2:
• Release torch trigger (no effect)
Step 3:
• Press torch trigger (no effect)
Step 4:
• Release torch trigger
• Super pulse function is ended.
• WF motor stops.
• Arc is extinguished after the preselected wire burn-back time expires.
• Gas post-flow time elapses.
