6-4. Lift-Arc

™

Start Procedure

Lift-Arc

TIG

With Lift-Arc

TIG selected, start

arc as follows:
1

TIG Electrode

Workpiece

Turn gas on. Touch tungsten

electrode to workpiece at weld start

point.

Hold electrode to

workpiece for 1-2 seconds

, and

slowly lift electrode. Arc is formed

when electrode is lifted.
Normal open-circuit voltage is not

present before tungsten electrode

touches workpiece; only a low

sensing voltage is present between

electrode and workpiece. The

solid-state output contactor does

not energize until after electrode is

touching workpiece. This allows

electrode to touch workpiece

without overheating, sticking, or be-

ing contaminated.

Application:

Lift-Arc is used for the DCEN

GTAW process when HF Start

method is not permitted, or to

replace the scratch method.

Do NOT Strike Like A Match!

Lift-Arc Start Method

Notes

Work like a Pro!

Pros weld and cut

safely. Read the

safety rules at
