The engine speed may need adjustment. Also, check fuse F1, and replace if open.
What to do if my Miller Big Blue 800 has low output at generator power receptacles?
The engine speed may need adjustment. Also, check fuse F1, and replace if open.
What to do if my Miller Inverter engine cranks but does not start?
First, check the fuel level. The optional low fuel shutdown stops the engine if the fuel level is low. Reset supplementary protector CB13. Check the battery and replace if necessary.
What to do if my Miller Big Blue 800 engine 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 the engine temperature is too high.
Why does my Miller Big Blue 800 battery discharge between uses?
Turn the Engine Control switch S1 off when the unit is not running. Clean the top of the battery with baking soda and water solution, then rinse with clear water. Recharge or replace the battery if necessary. Periodically recharge the battery (approximately every 3 months).
What to do if my Miller Inverter engine does not run at idle speed?
Turn the Process/Contactor switch to any position but Remote-TIG. Allow circuit breaker CB14 to reset.
What to do if my Miller Inverter has no weld output but generator power is okay?
First, ensure the Process/Contactor switch is in a 'Weld Terminals Always On' position, or in a 'Remote' position with a remote contactor connected to the Remote 14 receptacle RC14. Next, verify the Ampere Range switch position. Also, reset supplementary protector CB11 and CB5. If the issue persists, check and secure connections to Remote 14 receptacle RC14. If you have a faulty remote device connected to RC14, disconnect it. If the problem continues, check fuse F2, and replace it if it's open.
What to do if my Miller Inverter has no generator power or weld output?
Disconnect equipment from generator power receptacles during start-up. Check fuses F1 and F2, and replace if open. Reset supplementary protectors CB12.
What causes high weld output on my Miller Big Blue 800 Inverter?
Check the position of the Ampere Range switch and the Voltage/Amperage Adjust control. The engine speed may need adjustment.
What to do if my Miller Big Blue 800 has no generator power output at AC receptacles, but weld output is okay?
Reset the receptacle supplementary protectors and the GFCI receptacle.
