How to fix a Miller XMT 350 CC/CV with no weld output and is completely inoperative?
If your Miller Welding System has no weld output and is completely inoperative: * Place the line disconnect switch in the On position. * Check and replace the line fuses if necessary, or reset the circuit breaker. * Check for proper input power connections.
What to do if my Miller XMT 350 CC/CV has no weld output but the meter display is on?
If your Miller Welding System shows the meter display is on but there's no weld output, the input voltage may be outside the acceptable range. Check, repair, or replace the remote control. Alternatively, the unit may have overheated; allow it to cool with the fan on.
Why does my Miller XMT 350 CC/CV have erratic or improper weld output?
Erratic or improper weld output from your Miller Welding System can occur due to several reasons. Ensure you are using the correct size and type of weld cable. Also, clean and tighten all weld connections. Finally, verify that you have the correct polarity.
