OPERATION

THERMAL LED, MOTOR OVERLOAD

The thermal light illuminates when the wire drive motor draws too much current. If the thermal light illuminates, the wire drive will automatically shutdown for up to 30 seconds to allow the motor to cool. To start welding again, release the gun trigger, inspect the gun cable, liner (and conduit). Clean and make repairs as necessary. Start welding again when the problem has been safely resolved.

For best results, keep the gun cable and conduit as straight as possible. Perform regular maintenance and cleaning on the gun liner, conduit and gun. Always use quality electrode, such as L-50 or L-56 from Lincoln Electric.

POWER-UP SEQUENCE

All of the LEDʼs will briefly illuminate during power-up. If the gun trigger is activated during power up, the feeder will not operate until the gun trigger is released.

WIRE FEED SPEED/AMPERAGE DISPLAY

Idle

The left display shows the preset wire feed speed. The right display shows OCV. The wire feed speed LED is lit.

Welding

The value in the left display will be either amps or actual wire feed speed, depending upon the selection chosen in the set-up menu. The corresponding LED below the display will light. Note that actual WFS may not match preset WFS, if welding at low voltages with high wire feed speeds. The right display shows the arc voltage. If the wire feeder is connected for electrode negative welding, then the voltage display shows a minus sign.

After Welding

The display continues to hold the value of the amper- age or WFS and arc voltage for five seconds after welding stops. The amperage or WFS and voltage displays flash.

Set-Up Menu

Before entering the set-up menu:

Set the display to the desired wire feed speed (exam- ple: 400 inches per minute)

Measure the actual wire feed speed (example: 405 inches per minute)

Place the WFS knob in the 12 oʼclock position.

To enter the set-up menu, use paper clip to press the small button located on the case front.

Calibration of Amperage

Connect the feeder to a power source and grid. Adjust the power source and grid to the desired amperage. (example: 220 Amps)

Record the amperage display on the wire feeder. (example: 210 amps)

To enter the set-up menu, use paper clip to press the small button located on the case front.
