What causes melting tungsten when using my AWT Welding System?
- B
  Brooke HowardSep 12, 2025
  Melting tungsten when using your AWT Welding System can be due to poor gas flow, wrong size tungsten, or incorrect shielding gas. Adjust the flow rate of the shielding gas and check for loose fittings where gas could be leaking. Increase the tungsten diameter, referring to the chart for proper sizing. Only use 100% Argon when TIG welding.

What to do if I see holes in the weld bead (porosity) with my AWT Welding System?
- B
  Brittany MclaughlinAug 23, 2025
  If you notice holes in the weld bead (porosity) when using your AWT Welding System, it might be caused by an arc that is too long or moisture in the electrode. To resolve this, keep the ignited end of the electrode closer to the weld joint while welding, and replace the electrode with a new one.

Why is there excessive spatter when using my AWT Welding System?
- M
  Mindy ThomasAug 25, 2025
  Excessive spatter with your AWT Welding System is often due to an arc that's too long or a current that's too high. To correct this, keep the ignited end of the electrode closer to the weld joint while welding. Also, adjust the current on the front of the welder to a lower setting.

What does it mean when the overload light is on my AWT Welding System?
- P
  Phillip ZimmermanAug 27, 2025
  If the overload light is on in your AWT Welding System, it means the duty cycle has been exceeded. Allow the welder to cool for a minimum of 15 minutes before attempting to use it again.

How to fix poor penetration with my AWT Welding System?
- M
  Michael AllenAug 27, 2025
  Poor penetration with the AWT Welding System can result from several factors: * Poor joint preparation: Clean the weld joint of any dirt, grease, paint, or other possible contaminants. If the pieces being welded are of a heavy gauge, it may be necessary to bevel the edges. * Current too low: Adjust the current on the front of the welder to a higher setting. * Travel speed too fast: Slow down the travel speed of the electrode while welding.

What causes burn through when using my AWT Welding System?
- M
  Melissa JordanAug 29, 2025
  Burn through when using the AWT Welding System can be caused by high voltage, lack of tack welds, or slow gun travel. Try adjusting the voltage output to a lower setting and adjusting the wire speed to a slower setting. Also, increase your travel speed with the welding gun.

Why is material warping when using my AWT Welding System?
- A
  alexanderbassSep 22, 2025
  Material warping when using your AWT Welding System can be caused by insufficient clamping, insufficient tack welds, or too much heat in the material. Clamp the workpiece tightly and weld while the clamps are in place. Add more tack welds until rigidity and stiffness are developed. To reduce heat, it is best to spread the welding out around the area. This can be done by using stitch welding techniques, alternating sides, and/or taking your time and allowing the pieces to cool between passes.

Why is the tungsten contaminated on my AWT Welding System?
- D
  Dawn MurphySep 12, 2025
  If the tungsten is contaminated when using your AWT Welding System, it's likely due to contact of the tungsten with the base metal. Keep the tungsten 1/8 to 1/4 inch from the base metal. If the tungsten comes in contact, break off the end and resharpen immediately.

Why is there contamination in the weld bead of my AWT Welding System?
- D
  Denise CervantesSep 9, 2025
  Contamination in the weld bead when using your AWT Welding System can be due to contaminated tungsten, contaminated filler metal, or contaminated base metal. Remove the tungsten from the torch and break off the contaminated section and resharpen. Clean the filler metal, making sure to remove any oil, debris, or moisture. Clean the base metal, making sure to remove any oil, debris, coatings, or moisture. If the base metal is cold rolled steel, make sure to remove any mill scale.

What to do if the arc is triggered but will not start on my AWT Welding System?
- M
  Matthew MartinezSep 4, 2025
  If the arc is triggered but won't start on your AWT Welding System, it could be due to an incomplete circuit, incorrect tungsten, or no shielding gas. Check the ground connection to ensure it's on a freshly cleaned surface and close to the welding area, welding towards the ground connection is suggested. Consult the chart for the proper tungsten for the base metal being welded; in most cases, thoriated will be used for all steels. Make sure the shielding gas cylinder is turned all the way open and set at the correct flow rate.
