Start
• Press and hold torch trigger.
• Shielding gas is expelled (gas pre-flows).
• Arc ignites after the wire electrode makes contact with the workpiece at creep speed.
• Welding current flows.
• Wire feed speed increases to the set nominal value.
• The wire feed stop welding after the spot time elapses.
• Arc is extinguished after the wire burn-back time elapses.
• Gas post-flow time elapses.
Premature termination
• Release torch trigger.
