Trigger Mode Selection:

[REMOTE STD] Remote Standard

Typically used with a remote foot or hand control. REMOTE STD requires

a maintained contact closure to enable weld output. Amperage can be con-

trolled with a remote potentiometer, or it can be set at the control panel.

[REMOTE HOLD] Remote Hold

Remote control required. Allows the operator to weld without holding the

trigger closed. To start the weld, operator presses and releases trigger. To

stop the weld, the operator again presses and releases the trigger. In this

mode, only the output contactor is controlled by the remote control. Amper-

age must be set on the control panel.

[PPS] Pulse Control:

Reduces heat input to minimize distortion and increase travel speed. Set

PPS (pulse per second). The range is OFF−150 PPS. Background Am-

perage and Peak Amperage are not adjustable. Background Amperage

equals 25% of Peak Amperage. Peak Amperage Time equals 40%.

Lift-Arc Start

TIG Electrode

Workpiece

Touch tungsten electrode to work-

piece, hold for 1-2 seconds, slowly

lift electrode, and an arc forms.

Open-circuit voltage maybe present

before electrode touches workpiece.

High frequency starts arc when output

is enabled without making contact with

the workpiece. High frequency turns

off when arc is started.
