What to do if the KeyGree Welding System weld produces massive pores?
- R
  Ryan MartinezAug 18, 2025
  If your weld produces massive pores, several factors could be at play. It could be that the gas being used is impure, or the weld area is contaminated with oil stains or rust. Strong wind at the welding site or a lack of gas protection can also cause this issue. Ensure your gas is pure, the welding area is clean, and there's adequate gas shielding, and consider working in a less windy environment.

Why is the welding current unstable on my KeyGree Welding System, varying from high to low?
- H
  Heather FisherAug 21, 2025
  Unstable welding current in your KeyGree Welding System could stem from several issues. First, check if the torque knob of the wire feeder is set appropriately. Also, make sure the wire feed roll matches the welding wire or stick you're using. Heavily worn torch wire liners or contact tubes can also cause this problem. Finally, confirm the quality of the welding stick.

What to do if the torch switch starts welding but the current is high, the voltage unable to modulate, and the no-load voltage too high in KeyGree Welding System?
- R
  ryantaylorAug 23, 2025
  If the torch switch starts welding but the current is high, the voltage cannot be adjusted, and the no-load voltage is too high, examine the wire feeder control cable for any breaks. A defect in the welder control panel could also be the cause. Additionally, check the voltage and current feedback lines for any breaks.

What to do if the torch switch sends out gas and there is current output, but the wire feeder does not work on KeyGree Welding System?
- B
  Brenda MorseAug 26, 2025
  If the torch switch sends out gas and there's current output, but the wire feeder isn't working, check the wire feeder control cable for any breaks. Also, ensure the wire feeder isn't stuck. A problem with the wire feeding power or damage to the wire feeder itself could also be responsible.

What to do if my KeyGree Welding System torch is normal but can only weld low current?
- K
  Kathleen StewartAug 27, 2025
  If your torch seems normal but can only weld at low current, check the input power cord to ensure it isn't too thin or too long. Also, verify that the output cable isn't too thin or too long. If these aren't the issue, the main control panel might be damaged.

What to do if the torch switch starts welding but the voltage is maximum and non-adjustable on KeyGree Welding System? The feeding speed is adjustable.
- P
  perezdanielAug 30, 2025
  If, when starting welding with the torch switch, the voltage is at maximum and cannot be adjusted, but the feeding speed is adjustable, check the voltage and current feedback lines for any breaks. Alternatively, there might be a defect in the welder control panel.

What to do if Wire is fed without pressing the torch switch on KeyGree Welding System?
- R
  rodriguezstanleySep 1, 2025
  If wire feeds without pressing the torch switch, the welding torch switch might be damaged. Alternatively, the wire feeder control line could be short-circuited, the manual feeding button might be damaged, or the main control panel could be faulty.

What to do if the protection effect of the weld bead is not good after welding with KeyGree Welding System?
- A
  Audrey MeyerSep 3, 2025
  If the weld bead's protection isn't effective after welding, start by checking the gas pressure reducing valve for heating up. After welding, keep the torch in its original position to allow the gas to protect the high-temperature weld bead. You can also prolong the shielding gas lagtime.

What to do if the torch switch does not work when pressed and the protection light is off on KeyGree Welding System?
- M
  Maria CoxSep 6, 2025
  If the torch switch doesn't work when pressed and the protection light is off, check if the panel function light and the digital meter are on. Ensure the torch switch has good contact and the torch interface is properly connected. Also, check the contact of the wire feeder interface and whether the six-core control cable of the separately type machine is damaged.

What to do if the gas meter does not heat up on KeyGree Welding System?
- B
  bradleysummerSep 8, 2025
  If the gas meter isn't heating up, check if the heating power voltage is normal. Ensure the heater plug is fully inserted. Verify that the resettable fuse inside the welder is intact. The electric heater inside the gas meter might also be damaged.
