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
The welding parameters change at the specified times between main program P
main program P
Step 2
