  If you're experiencing big spatter with your HUGONG Welding System, it could be due to several reasons. The welding current and voltage might not be properly matched, so try adjusting the welding data. Also, check for oil, rust, or water on the wire or work-piece and clean them if necessary. Ensure the wire isn't stretching too far outside the nozzle; if it is, press the torch closer to the work-piece. Finally, the nozzle diameter may be too large, consider switching to a more suitable nozzle.

  If you find that your HUGONG Welding System is producing welds with air holes, there are a few potential causes. First, check for excessive oil, rust, or water on the wire or work-piece and clean them thoroughly. Second, ensure proper CO2 gas protection by verifying adequate gas flow, gas purity, and absence of nozzle blockages or gas leakages, also ensure there is not too much wind. Finally, the wire might not have enough silicon and manganese; in that case, switch to a more suitable wire. Improving the gas connection may also help.

What to do if the penetration is not enough with my HUGONG Welding System?
- A
  Adam CooleyAug 25, 2025
  If you're experiencing insufficient penetration with your HUGONG Welding System, it may be due to a welding current that is too small. Increasing the welding current might resolve this. Additionally, check if the wire is extending too far from the nozzle and press the torch closer to the work-piece. Also, the groove preparation could be inadequate, with too small an angle or gap, consider changing the welding technology process.

Why does my HUGONG INVERMIG 350III Welding System keep producing cracks in the weld?
- W

  If your HUGONG Welding System is producing cracks, make sure that the current and voltage are properly matched by adjusting the welding data. Too much water in the gas may also be a contributing factor, so try changing the gas flow. Also, check for oil, rust, or water on the wire or work-piece and clean the wire and work piece.

How to prevent undercut when using my HUGONG INVERMIG 350III?
- J
  Jessica AlvaradoAug 28, 2025
  If your HUGONG Welding System is creating undercuts, it could be because the arc length is too small and the welding speed is too fast. Try increasing the arc length and slowing down the welding speed. Also, the torch location might not be optimal, and the welding current could be too small. Adjust the torch location and increase the welding current to see if that helps.

What causes slag inclusion in my HUGONG INVERMIG 350III and how can I fix it?
- L
  Lawrence WhiteAug 30, 2025
  If your HUGONG Welding System is experiencing slag inclusion, it might be because the former molten slag of the welding bead isn't being properly cleaned; make sure to remove molten slag. Also, small current, too much weld slowly deposition, to much swing during welding can cause this issue. Increasing the current and reducing the swing during welding may resolve the problem.

Why is the fan not turning or turning slowly on my HUGONG INVERMIG 350III?
- C
  Carol ReynoldsAug 31, 2025
  If the fan in your HUGONG Welding System isn't turning or is turning slowly, the input power may be losing a phase; check and restore the normal input power. Alternatively, the power switch might be broken, in which case you should change the power switch.

Why is the protection LED on my HUGONG Welding System lit?
- K
  Kevin TaylorSep 4, 2025
  If the protection LED is on in your HUGONG Welding System, it could indicate that the internal machine is overheating. In this case, wait until the temperature decreases and the light turns off. Alternatively, the thermal relay might be broken, and you may need to change thermal relay.

What to do if the current and voltage display is not working on my HUGONG Welding System?
- J
  Jennifer ParksSep 6, 2025
  If there is no display of current and voltage on your HUGONG Welding System, the current and voltage display might be broken, so consider changing the display. Alternatively, there could be a loose connection, check where is the loss connection and tighten it.
