The STATUS LED is alternating between red and green every second. The unit tries to recover after 30 seconds and may repeat sequence.79The feeder does power up - no display, no cold feed.80No shielding gas.80Inconsistent wire feeding or wire not feeding but drive rolls turning.80Variable or "hunting" arc.81Poor arc starts with sticking or"blast-offs", weld porosity, narrow and ropy looking bead.81The wire feed speed/amperage and voltage/trim display work during preset but show nothing during welding.81Major physical or electrical damage is evident when the sheet metalcover(s) are removed.82No wire feed, solenoid or arc voltage. The STATUS LED's are steady green.82No control of wire feed speed. All STATUS LEDs are steady green.The preset wire feed speed is adjustable on the front panel.82No 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.82The 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.82The purge switch 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, and wire drive unit.83The 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, and wire drive unit.83The voltmeter on the wire feeder does not function properly even though the STATUS LEDS are steady green.83The displays are blank (not lit). The wire feeds when the gun trigger is activated.84The dual procedure is not functional when using the remote Dual Procedure switch. The STATUS LEDs are steady green on the power source, and wire drive units.84Section G - Electrical Diagrams97Tamaño: 9 MBPáginas: 108Language: EnglishManuales abiertas
