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.

Why is the welding current unstable on my Jasic MIG 400P Welding System?
- B
  bryanbuchananAug 28, 2025
  If you're experiencing unstable welding current with your Jasic Welding System, consider the following: 1. Ensure the pressure arm on the wire feeder is properly adjusted. 2. Verify that the drive roll matches the welding wire you are using. 3. Check the contact tip of the welding torch for wear and replace if necessary. 4. Inspect the guide tube in the torch and replace if worn. 5. Ensure you are using good quality welding wire.

Why is the fan not working on my Jasic MIG 400P?
- T
  Theresa HolmesAug 29, 2025
  If your Jasic Welding System's fan isn't working correctly, it could be due to: * A loose 3-phase power cord. Reconnect the cord. * A phase failure. Address the phase failure. * Overly low mains voltage. Welding can continue once the voltage recovers.

What to do if there is no output current when pushing the torch trigger on my Jasic Welding System?
- J
  Justin WoodsAug 31, 2025
  If the torch trigger is pushed, wire feeder works and gas flows, but there is no output current on your Jasic Welding System, and the protection LED is off, it could be due to: * The earth cable not being well connected to the workpiece. Reconnect it. * The control cable of the wire feeder not being well connected. Reconnect it. * The wire feeder or welding torch failing. Repair the wire feeder or welding torch.

How to prevent electrode sticking with my Jasic Welding System?
- A
  allenclaudiaSep 2, 2025
  If the electrode is sticking during welding with your Jasic Welding System, it could be because the arc force current is too low. Increase the arc force current appropriately.

What to do if the wire feeder doesn't work on my Jasic MIG 400P Welding System?
- M
  Mrs. Connie HayesSep 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.

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.
