  If there is output current when pushing the torch trigger to feed gas, but the wire feeder does not work with your Jasic Welding System, it could be due to: * A broken control cable of the wire feeder. Repair or replace the cable. * A clogged wire feeder. Resolve the clogging problem. * The wire feeder failing. Repair it. * The control PCB or wire feeding power PCB inside the machine failing. Replace the PCB.

Why is the arc easy to break on my Jasic MIG 400P?
- C
  Charles SanchezSep 14, 2025
  If the arc is easy to break when using your Jasic Welding System, it's likely that the arc breaking voltage is too low. Increase the arc breaking voltage properly.

Why does the electrode holder get so hot on my Jasic Welding System?
- A
  Alice PatelSep 9, 2025
  If the electrode holder becomes very hot while using your Jasic Welding System, it's likely because the rated current of the electrode holder is lower than the actual working current. Replace it with one that has a higher rated current.

Why can't I start a normal arc with my Jasic MIG 400P Welding System?
- C
  Christopher ScottSep 6, 2025
  If you are unable to start a normal arc with your Jasic Welding System, it might be due to a phase failure in the mains power supply or a poorly connected power cord. Address the phase failure or reconnect the power cord.

Why does my Jasic Welding System display “Err 001”?
- N
  Norma ButlerAug 21, 2025
  If the Jasic Welding System displays “Err 001”, it could be due to several reasons: * The mains voltage might be too low. In this case, welding can resume once the voltage recovers. * The mains voltage might be too high. Disconnect the power supply and reconnect it after the voltage stabilizes. * The auxiliary power might have failed. If so, replace the faulty circuit board of the auxiliary power.
