Freedom 38 PPA engine-driven plasma system

The Freedom 38 PPA is an engine-driven, fully self-contained plasma system designed for cutting and gouging work in remote locations. A 38 kW Deutz T4i diesel genset provides all the power needed for heavy-duty, off-the-grid jobs, from pipeline construction and repair to plant shutdowns. The enclosure also houses an air compressor and Powermax125® plasma system, completely integrated and ready to go. The go-anywhere solution lets you:

  • Improve safety by reducing hazards from oxyfuel and carbon arc gouging
  • Increase productivity with the ability to cut and gouge any electrically conductive metal faster than oxyfuel or grinding
  • Finish jobs faster and reduce costs by eliminating cylinder rentals
