Setup

For typical system connections refer to

Section 6-1.

Rotate Mode Switch to LIFT-ARC TIG posi-

tion as shown.

The open-circuit voltage is shown in the

Left Display with the Volts Indicator lit. Pre-

set amperage is shown in the Right Display

with the Amps Indicator lit.

Normal open-circuit voltage is not present

before the electrode touches the work-

piece, instead a low sensing voltage is

present. The sensing voltage allows the

electrode to touch the workpiece without

overheating, sticking, or getting contami-

nated.

Operation

The Adjust Control is used to set desired

preset amperage.

. If a remote control is used for amper-

age adjustment, the adjustment will

function as a percentage of the preset

amperage.

. For best results, firmly touch the tung-

sten electrode to the workpiece at the

weld start point. Hold electrode to

workpiece for 1-2 seconds, and lift

electrode. An arc will form when the

electrode is lifted. To minimize arc flare

at the end of the weld, pull back the

electrode quickly to extinguish the arc.
