1st cycle
• 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 is flowing (start program P
START
, spot time starts)
• Slope to main program P
A
• After the set spot time elapses, slope goes to end program P
END
.
• Wire feed motor stop welding.
• Arc is extinguished after the pre-selected wire burn-back time elapses
• Gas post-flow time elapses.
2nd cycle
• Release torch trigger
Releasing the torch trigger (step 2) interrupts the welding process even if the spot time has not
yet elapsed (slope to end program P

).
