Why does my Power Fist 8785115 have porosity?
- T
  Travis GibsonAug 15, 2025
  Porosity, characterized by small cavities or holes in the weld metal, can occur for several reasons. First, the arc length might be too long, in which case you should shorten it. Second, the workpiece may be dirty, contaminated, or contain moisture; remove any moisture, paint, grease, mill scale, oil, or dirt from the base metal. Finally, damp electrodes can cause porosity, so ensure you're using only dry electrodes.

What to do if Power Fist 8785115 Welding System has no arc?
- J
  Justin NewmanAug 21, 2025
  If your Power Fist Welding System is not producing an arc, there are a couple of things to check. First, ensure that you have a complete welding circuit by checking that the earth lead is connected and inspecting all cable connections. Second, verify that the machine is switched on and has a power supply.

Why is my Power Fist 8785115 lacking penetration?
- K
  Kristen CraigAug 26, 2025
  Lack of penetration in your Power Fist Welding System welds could stem from a few issues. Primarily, there might be insufficient heat input, so increase the amperage or choose a larger electrode. It could also be due to poor welding technique, so ensure you are using the correct technique or seek assistance. Lastly, poor joint preparation could be the cause; check the joint design and fit-up, ensure the material isn't too thick, and seek assistance for correct joint design and fit-up if needed.

Why does weld sit on top with Power Fist Welding System?
- A
  Amy SawyerAug 28, 2025
  If your weld sits on top and lacks fusion when using your Power Fist Welding System, it could be caused by insufficient heat input. Increase the amperage or choose a larger electrode. Also, the workpiece may be dirty, contaminated, or contain moisture. Remove any moisture, paint, grease, oil and dirt, including mill scale from the base metal. Finally, poor welding technique can cause this issue, so use the correct welding technique or seek assistance for the correct technique.

What causes distortion in Power Fist Welding System?
- A
  Andre CannonAug 31, 2025
  Distortion, or movement of the base metal during welding with your Power Fist Welding System, can occur due to excessive heat input; reduce the amperage or use a smaller electrode. Poor welding technique can also cause distortion, so ensure you're using the correct technique or seek assistance. Lastly, poor joint preparation and/or joint design can contribute; check the joint design and fit-up, ensure the material isn't too thick, and seek assistance for the correct joint design and fit-up if needed.

How to prevent burn through with Power Fist 8785115?
- D
  Denise RossSep 3, 2025
  Excessive penetration, leading to burn-through, with your Power Fist Welding System can be attributed to excessive heat input. To resolve this, reduce the amperage or use a smaller electrode. Another potential cause is incorrect travel speed; try increasing the weld travel speed.

Why does Power Fist Welding System electrode have unusual arc?
- C
  Christopher CookSep 10, 2025
  If the electrode welds with different or unusual arc characteristics on your Power Fist Welding System, the cause may be incorrect polarity. Change the polarity and check the electrode manufacturer for correct polarity.
