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.
• Super pulse function is ended.
• WF motor stops.
• Arc is extinguished after the preselected wire burn-back time expires.
• Gas post-flow time elapses.
