Questions and answers
MILL;ER WELDING MACHINE,, INVERSION AC ,354MP, SERIAL NO. LA278806 HAS NO OUTPUT,,, WIRED FOR 240 VOLT ,THREE PHASE SUPPLY,, WIRE FEED FEEDS WIRE , MACHINE SHOWS 19 VOLTS,,, THE TWO CIRCUIT BREAKERS IN BACK OF MACHINE ARE OUT,PUTTING PROPER VOLTAGES, GROUND CABLE CHECKS OK. POSSIBLE CAUSE OF PROBLEM AND ALSO A TROUBLESHOOTING GUIDE PLUS WIRING SCHEMATIC NEEDED
SEE ABOVE MESSAGE BY THOMAS EASTERDAY
Possible causes of no weld output in a Miller Electric welding machine include:
1. Line disconnect switch is Off.
2. Blown line fuse(s) or tripped circuit breaker.
3. Improper input power connections.
4. Input voltage outside acceptable range.
5. Faulty or disconnected remote control.
6. Unit overheated—requires cooling.
7. Excessive ground current detected (if equipped with ground current sensor).
You can find the troubleshooting guide and wiring schematic in Sections 4-5, 4-6, and 4-7 of the manual.
