How the Percussion Welder works.

An electrical arc is generated between the materials to be joined which supplies heat to melt the faying (joining surfaces) of the two metals. At the moment the surfaces become molten, contact (percussion) is made. Upon percussion, the arc is extinguished and a strong weld is formed with no filler material, preserving the properties of the original metals.

More capabilities. Fewer limitations.

  • Join dissimilar metals
  • Weld at just about any orientation
  • Weld within a few thousandths of an inch of heat sensitive materials (miniscule heat affected zone)
  • Weld without reducing the hardness of metal, increasing resistance or introducing incompatible material (no filler material required)
  • Little or no incremental resistance at the weld joint because impurities are expelled during the percussion phase and there’s no filler material
  • Weld metals with low structural integrity


  • Strong welds capable of withstanding shock, vibration and temperature extremes


  • No electrodes that wear out and need replacing
  • No consumables which reduces material waste
  • Low power consumption


  • Low level of skill required to weld


  • 5 year warranty
