1st step
Press and hold torch trigger
• Shielding gas is expelled
• Wire-feed motor runs at "creep-start speed".
• Arc ignites after the wire electrode makes contact with the workpiece, welding current flows.
• Changeover to pre-selected WF speed.
2nd step
Release torch trigger
• WF motor stops.
• Arc is extinguished after the set wire burn-back time elapses.
Advantage: Prevents fusing of the wire electrode into the weld pool.
• Gas post-flow time elapses.
