Selection
• Select non-latched special mode
.
Step 1
• Press and hold torch trigger
• Shielding gas is expelled (gas pre-flows)
The arc is ignited using liftarc.
• Welding gas flows with pre-selected setting in start program “P
START
”.
• After the “tstart” ignition current time elapses, the welding current rises with the set upslope time “tS1”
to the main program “P
A
”.
Step 2
• Release torch trigger.
• The welding current reduces with the downslope time “tSe” to the end program “P
END
”.
• After the end current time “end” elapses, the arc will extinguish.
• Gas post-flow time elapses.
