Why doesn't my Miller Welding System engine run at idle speed?
For CC models of your Miller Welding System, place the Stick/TIG Selection switch in the Stick position. For CC/CV models, place the Process/Contactor switch in any position but Remote On/Off Switch Required- TIG. Check for an obstructed throttle solenoid.
Why does the engine on my Miller Big Blue 400D Welding System suddenly stop?
If the engine of your Miller Welding System suddenly stops, first check the oil level. The automatic shutdown system may stop the engine if the oil pressure is too low or the engine temperature is too high.
How to troubleshoot low weld output on a Miller Welding System?
If your Miller Welding System has low weld output, first check the engine speed and adjust it if necessary. Also, check fuses F1 and F2, and replace them if they are open.
What to do if there is no weld output or generator power output on my Miller Big Blue 400D?
If your Miller Welding System has no weld output or generator power output at AC receptacles, disconnect equipment from generator power receptacles during start-up. Check fuses F1 and F2, and replace them if open. Reset supplementary protector CB12.
Why won't the engine crank on my Miller Big Blue 400D?
If the engine of your Miller Welding System will not crank, check the battery and replace it if necessary. Ensure that the battery connections are secure and tight. Also, check if circuit breaker CB10 is open.
How to troubleshoot low open-circuit voltage on a Miller Big Blue 400D?
If your Miller Welding System has low open-circuit voltage, check the engine speed and adjust if necessary.
What to do if my Miller Welding System engine slowly stopped and won't restart?
If the engine of your Miller Welding System slowly stopped and cannot be restarted, check the fuel level and the engine air and fuel filters.
Why is the output high at the three-phase generator on my Miller Big Blue 400D Welding System?
If your Miller Welding System has high output at the optional three-phase generator/receptacle RC5, check the engine weld/power speed, and adjust if necessary.
Why does my Miller Big Blue 400D engine start but stop when the switch is released?
If the engine of your Miller Welding System starts but stops when the Engine Control switch is released, check the oil level. The automatic shutdown system stops the engine if oil pressure is too low or engine temperature is too high.
Why is the weld output too high on my Miller Welding System?
If your Miller Welding System has high weld output, check the engine speed and adjust if necessary.
