What to do if CIGWELD Transmig 310 Welding System mains supply voltage is ON but Indicator light is not lit and welding arc can not be established?

  If the mains supply voltage is ON, but the indicator light is not lit and a welding arc cannot be established, it may be due to a blown primary fuse. Replace the primary fuse. Alternatively, there may be a broken connection in the primary circuit, in which case you should have an Accredited CIGWELD Service Agent check the primary circuit.

  If the mains indicator light is not lit but a welding arc can be established, it is likely due to a burnt out indicator light. Have an Accredited CIGWELD Service Agent replace the indicator light.

  If the mains supply voltage is ON and the indicator light is lit, but nothing happens when the torch trigger switch is depressed, the torch trigger switch leads may be disconnected. Reconnect them.

What to do if CIGWELD Welding System mains supply voltage is ON, no wire feed but gas flows from the MIG Torch when the torch trigger switch is depressed?

  If the mains supply voltage is ON, there is no wire feed, but gas flows from the MIG Torch when the torch trigger switch is depressed, it could be because the electrode wire is stuck in the conduit liner or contact tip (burn-back jam). Check for a clogged or kinked MIG Torch conduit liner or a worn contact tip, and replace any faulty components. It could also be due to a faulty control PCB, in which case you should have an Accredited CIGWELD Service Agent investigate the fault.

What to do if CIGWELD Welding System has inconsistent wire feed?

  Dennis SmithNov 20, 2025
  If your CIGWELD Welding System is experiencing inconsistent wire feed, consider these potential causes and solutions: * If the wire spool brake is too tight, the feed roller driven by the motor in the cabinet will slip. * If the wire spool brake is too loose, the wire spool can unwind and tangle. * Worn or incorrect feed roller size: use a 'U' groove drive feed roller matched to the aluminum wire size you are welding. * Mis-alignment of inlet/outlet guides: wire will rub against the mis-aligned guides and reduces wire feedability. * Liner blocked with swarf: increased amounts of swarf is produced by the electrode wire passing through the feed roller when excessive pressure is applied to the pressure roller adjuster. * Incorrect or worn contact tip: the contact tip transfers th...
