How to fix porosity in CIGWELD Welding System?
- E
  Emma AndrewsAug 20, 2025
  To address porosity in your weld, start by cleaning any contaminants from the workpiece. Keep the MIG torch nozzle as close as possible to the workpiece. Make sure the gas holes are clear and gas is flowing from the torch nozzle. Protect the weld area from wind, or increase the gas flow. Verify that the gas cylinder isn't empty and the flow meter is correctly set to 15 liters per minute. Check for gas leaks from the regulator/cylinder connection to the gas hose at the power source. Finally, ensure the hose from the solenoid valve to the torch adapter is intact and properly connected.

Why CIGWELD Transmig 330 Welding System has excessive spatter?
- D
  destiny05Aug 25, 2025
  Excessive spatter can occur if the arc voltage is too high or too low. To fix this, lower the voltage by reducing the Voltage Control switches positions or turn the Wirespeed control knob clockwise if the voltage is too high. If the voltage is too low, raise the voltage by increasing the Voltage Control switches or turn the Wirespeed control knob anti-clockwise.

How to resolve undercut in CIGWELD Transmig 330 Welding System?
- C
  codyzamoraAug 27, 2025
  If you're experiencing undercut, it could be due to several factors. If the welding arc voltage is too high, reduce it by adjusting the Voltage Control switches positions or turn the Wirespeed control knob clockwise. Also, ensure your torch angle is correct and adjust it if necessary. Finally, if there's excessive heat input, increase the torch travel speed or reduce welding current by reducing the Voltage Control switches positions and turn the Wirespeed control knob anti-clockwise.

What causes lack of penetration in CIGWELD Transmig 330 and how to fix it?
- P
  Paula CarsonAug 28, 2025
  Lack of penetration can be caused by a welding current that is too low. Increase welding current by increasing turn the Wirespeed control knob clockwise and increasing Voltage Control switch positions. It can also happen if the joint preparation is too narrow or the gap is too tight, so increase the joint angle or gap. Finally, the shielding gas may be incorrect, so change to a gas which gives higher penetration.

How to fix irregular weld shape in CIGWELD Transmig 330 Welding System?
- J
  Jenna NewtonAug 30, 2025
  An irregular weld shape may be due to incorrect voltage and current settings; adjust these using the Voltage Control switches positions and the Wirespeed control knob. Another cause may be that the wire is wandering, in which case you should replace the contact tip. The issue could also stem from incorrect shielding gas, so check your gas selection. Finally, insufficient or excessive heat input can also lead to this problem; adjust the Wirespeed control knob or the Voltage Control switches.

What to do if CIGWELD Transmig 330 has weld cracking?
- T
  Tara MartinezSep 1, 2025
  Weld cracking can occur due to several reasons. If weld beads are too small, decrease torch travel speed. If weld penetration is narrow and deep, reduce current and voltage and increase the MIG Torch travel speed or select a lower penetration shielding gas. Excessive weld stresses can also be a factor, so increase weld metal strength or revise the design. If there's excessive voltage, decrease it by reducing the Voltage Control switches. Lastly, if the cooling rate is too fast, slow it down by preheating the part to be welded or cool it slowly.

What to do if CIGWELD Transmig 330 Welding System has lack of fusion?
- U
  uperezSep 3, 2025
  If you're experiencing a lack of fusion, this can be due to the arc voltage being too low. To resolve this, increase the arc voltage by increasing the Voltage Control switches position.

Why arc does not have a crisp sound in CIGWELD Transmig 330 Welding System?
- A
  Alicia RodriguezSep 5, 2025
  If the arc in your CIGWELD Welding System doesn't have a crisp sound, it might be because the MIG torch is connected to the wrong voltage polarity on the front panel. To fix this, connect the MIG torch to the positive welding terminal (+) for solid wires and gas shielded flux cored wires.

What causes cold weld puddle in CIGWELD Transmig 330?
- E
  edouglasSep 7, 2025
  A cold weld puddle may be caused by several factors: * A faulty rectifier unit: Have an Accredited CIGWELD Service Agent test then replace the faulty component. * Loss of a phase in the Mains supply voltage: Check mains power. * Loose welding cable connection: Check all welding cable connections. * Low Mains supply voltage: Contact supply authority.

What to do if CIGWELD Welding System indicator light is ON but welding arc can not be established?
- M
  Michael FrazierSep 9, 2025
  If the indicator light is on but a welding arc cannot be established, it might be because the Coarse Voltage Control switch is in the STANDBY position. Switch the Coarse Voltage Control switch to a welding setting.
