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.
• Change over to pre-selected wire speed (main program P
A
).
Step 2
• Release torch trigger.
• WF motor stops.
• Arc is extinguished after the preselected wire burn-back time expires.
• Gas post-flow time elapses.
