- Symptoms
- Major physical or electrical damage is observed when cover wraparound is removed.
- Machine is dead — no output — no fan — no display.
- No output but fan operates and the meter display is on.
- No output or reduced output the first time power is applied to machine.
- Output turns on momentarily, then switches off and repeats cycle.
- Remote output control not functioning. Machine performs well on LOCAL control.
- No ouput. Main fuses open, indicating excessive current draw.
- Machine does not produce more than 250 amps on meter (while welding) when connected to 3-phase supply.
- Machine does not produce more than 250 amps on meter (while welding) while connected to singlephase supply
- Machine operates okay at 230 VAC or lower. No output at 380 VAC or higher
- Meter reads low voltage (1-2 VDC), and output is extremely low or no output.
- Poor welding, weld settings drift, or output power is low.
- Welding “too hot”. Actual weld current is considerably higher than display indicates.
- Poor stick electrode performance. Arc pops out.
- Machine makes “squealing” noise while under load when welding. Output power is low (less than 20 VDC on meter @ 100 amps). Input voltage 230 VAC or lower.
