1 Weld Process Switch

Use switch to select weld process.

In Stick position (down), weld output goes On and Off with Power switch.

In GTAW (TIG) position (up), remote control device turns on and adjusts weld output of unit as limited by Amperage control. Built-in arc starter comes on when needed to start or stabi- lize welding arc. No adjustments needed for arc starter.

2Pilot Light

3Power Switch

Use switch to turn unit, fan, and pilot light On and Off.

4 Amperage Control

For Stick (SMAW), use control to adjust amper- age within range selected by the Range/Polar- ity Switch.

5 Stick (SMAW) Table

Use table to find approximate Stick amperage output at Amperage control setting.

See Section 6-2for example of front panel am- perage control.

For remote amperage control used when TIG (GTAW) welding, front panel Amperage control setting is the maximum amperage percentage available at the remote control device.

See Section 6-3for example of remote amper- age control.

6 Range/Polarity Switch

Use switch to select range and polarity of weld output.

For Direct Current Electrode Negative (DCEN), use Electrode Negative position.

For Direct Current Electrode Positive (DCEP), use Electrode Positive position.

For alternating current (AC), use range needed for welding application − AC Low or AC High position − see Warning.

See Section 6-4to find suggested type of weld output for application.

7 High Temperature Shutdown Light

Lights when unit overheats and shuts down (see Section 7-2).

8 Output On (Contactor) Light

Lights when output (contactor) and unit power are on.
