Start
• Press and hold torch trigger.
• Shielding gas is expelled (gas pre-flows).
• Arc ignites after the wire electrode makes contact with the workpiece.
• Welding current flows.
• The wire feed stops after the pulse time expires.
• Arc is extinguished.
• The process is repeated after the pause time elapses.
End
• Release torch trigger, wire feed stops, arc is extinguished.
NOTE
When the torch trigger is released, the welding process is also interrupted even before
the spot time elapses.
