What to do if there is no wire feeding in my ESAB MIG400iCCCV?
- J
  Joseph McleanAug 13, 2025
  If your ESAB Welding System isn't feeding wire, it could be due to several reasons. First, check if the control cable is disconnected and reconnect it if necessary. Also, inspect the fuse on the back of the machine and replace it if it's broken. The wire feeder motor might be defective, requiring repair or replacement. Lastly, a defective control PCB could also be the cause, in which case you should replace it.

Why my ESAB MIG400iCCCV Welding System doesn’t work after pressing torch trigger?
- R
  Ronald DixonAug 16, 2025
  If your ESAB Welding System machine doesn’t work after pressing the torch trigger, the issue might stem from a broken fuse (1A), which you should replace. Alternatively, the torch trigger itself could be defective; in that case, connect the control cable to the torch switch. If the machine trips, ensure you're working within a suitable duty cycle. A broken control PCB could also be the cause, so consider replacing it.

What to do if my ESAB Welding System has no OCV?
- A
  andreafitzpatrickAug 20, 2025
  If your ESAB Welding System shows no OCV, it could be due to over voltage, voltage lack, or lack of phase; in this case, restart the work when the voltage returns to normal level. Another reason might be that the machine is overheated, so restart work when the temperature returns to normal level. Also, the power switch could be defective, and it should be replaced.

How to fix no gas issue in my ESAB MIG400iCCCV Welding System?
- S
  Steven ValenzuelaAug 27, 2025
  If there's no gas flow in your ESAB Welding System, start by checking the fuse (1A) and replace it if defective. Next, ensure the gas hose is properly connected; if not, reconnect it. Also, the gas hose might be staved or jammed, so check the gas route. Finally, the solenoid could be defective, requiring repair or replacement.

Why are there no values displayed on the current meter or voltage meter of my ESAB Welding System?
- T
  Tina CampbellSep 8, 2025
  If there are no values displayed on the current meter or voltage meter of your ESAB Welding System, it could be due to broken meters, which would need replacement. Another cause might be a disconnected connecting lead, so try reconnecting it. Finally, a defective main control PCB could also be the culprit, requiring replacement.
