Lift-Arc is used for the DCEN
GTAW process when HF Start
method is not permitted.
Select Lift-Arc at Process/Contac-
tor switch.
Turn gas on.
1
Touch or scratch.
2
Lift at any angle.
Touch tungsten electrode to
workpiece at weld start point.
Slowly lift electrode. Arc is started
when electrode is lifted.
Maintain shielding gas coverage
and eliminate tungsten and work-
piece contamination by using
Auto-Crater or Auto-Stop to end
the arc.
See Section 6-5 to adjust
Auto-Stop and Auto-Crater.
Arc End With Auto-Stop:
1
While welding.
2
Lift torch to start Auto-Stop.
Arc stops.
3
Move torch back down to
maintain gas coverage and
prevent contamination.
Arc End With Auto-Crater:
Remote control is not needed
when using Auto-Crater.
1
While welding.
2
Lift torch slightly to start
Auto-Crater end (current is
reduced).
3
Lower torch. Weld current
ramps down.
4
Shielding gas continues until
shut off.
