What to do if the wire feeder doesn't work on my Jasic MIG 350P?
- R
  Robert GoodSep 4, 2025
  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.

How to reduce spatter during arc ignition on my Jasic Welding System?
- R
  ricky85Sep 18, 2025
  If you're experiencing excessive spatter or an overly big molten pool during arc ignition with your Jasic Welding System, it's likely that: * The initial current is too high. Reduce it appropriately. * The initial time is too long. Shorten it properly.

What to do if there is no response when pushing the torch trigger on my Jasic MIG 350P?
- C
  Christopher BarnesSep 16, 2025
  If there is no response when pushing the torch trigger on your Jasic Welding System, and the protection LED is off, it could be due to: * The welding torch not being well connected to the wire feeder. Reconnect it. * The control cable of the wire feeder not being well connected to the welding power supply. Reconnect it. * The torch trigger failing. Repair or replace the welding torch.

Why is the arc easy to break on my Jasic MIG 350P Welding System?
- V
  Vanessa RhodesSep 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?
- S
  Sandra TorresSep 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 is the gas regulator not heating up on my Jasic Welding System?
- M
  Melissa SmithSep 7, 2025
  If the gas regulator cannot be heated on your Jasic Welding System, check the following: * Ensure the heater plug is well connected. * Check for a shorted heater wire and repair if necessary. * See if the resettable fuse inside the machine functions; shut down and restart the machine. * The heater inside the gas regulator might be damaged; consider replacing it.

Why can't I start a normal arc with my Jasic MIG 350P?
- L
  Lori SawyerSep 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”?
- M
  Mr. Malik MendozaAug 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.
