- Symptoms
- Major physical or electrical damage is evident when the sheet metal cover(s) are removed.
- No control of wire feed speed. All STATUS LEDs are steady green. The preset wire feed speed is adjustable on the Control Box.
- No welding arc voltage when the gun trigger is activated. The wire feeds normally and the gas solenoid functions properly. The STATUS LEDs are steady green on the wire drive unit and the Control Box.
- The wire feed speed does not change when welding current is established. The WFS stays at the run-in speed. The STATUS LEDs are steady green.
- The purge switch on the wire drive unit does not activate the gas solenoid, but gun trigger closure in the MIG or pulse modes does activate the solenoid. The LEDs are steady green on the power source, Control Box and wire drive unit.
- The COLD INCH/GAS PURGE switch does not turn on the wire drive motor but gun trigger closure in the MIG or Pulse modes does activate the wire drive motor. The LEDs are steady green on the power source, Control Box and wire drive unit.
- The voltmeter on the Control Box does not function properly even though the STATUS LEDSare steady green.
- The ammeter on the Control Box does not function properly even though the STATUS LEDs are steady green.
- The display and/or indicator LEDs do not change when their corresponding switches and or knobs are activated or turned.
- The mode and/or settings change while welding under normal conditions.
- The feeder resets when the gun trigger is activated. The LEDs blink and the displays are intermittent.
- The displays are blank (not lit). The wire feeds when the gun trigger is activated.
- The dual procedure is not functional when using the remote Dual Procedure switch. The STATUS LEDs are steady green on the power source, Control Box and wire drive units.
- The wire feed speed is consistent and adjustable, but runs at the wrong speed.
- The unit shuts off while welding or attempting to weld. The STATUS LED is alternating between red and green every second. The unit tries to recover after 30 seconds and may repeat sequence.
- When the gun trigger is activated, the drive rolls do not turn. The arc voltage is present and the solenoid is energized. The STATUS LEDs are steady green.
- The wire is feeding rough or not feeding, but the drive rolls are turning.
- When in CC modes with the optional “MX” or “MXP” panels, the otput does not energize.
- The gun tip seizes in diffuser.
- Poor arc striking with sticking or “blast-offs”. The weld bead may be narrow and ropy with weld porosity.
- The arc is variable and/or hunting. The power source, Control Box and drive units seem to be operating properly.
