Easy-to-use interface

  • All you need to do is power it up, select your material, and set the material thickness range.


  • The fan only runs when needed, reducing the dust and debris that is pulled into your machine.

Infinite amperage control

  • With finer control you are able to operate at a broader range.

Inverter-based, AC/DC power source

  • Uses less power which allows you to have a more consistent welding arc.


  • Weighs 50 lbs. so it is EZ to take wherever you go.

High frequency starts

  • Non-contact arc starts eliminate tungsten and material contamination, allowing you a clean weld.


  • You won’t waste or need adjustment and it will provide optimum shielding based on amperage.
