SoftMount Gun

SoftMount™ Gun

The SoftMount™ Gun is designed to mechanically fine adjust its position to a stamped hole to consistently projection weld a fastener. It is ideal for robot applications where part dimensions, hole locations, or tooling are slightly inconsistent.

Available in two configurations:

  • Standard Feed Process (SFP) for nuts & stud welding applications
  • Inverted Feed Process (IFP) for nut welding applications

Controlled Pulse Resistance Welding

Controlled Pulse Resistance Welding (CPRW)

Controlled Pulse Resistance Welding (CPRW) is a new projection welding process built on the fundamentals of resistance welding and MFDC machines but leverages technological advances to refine the process further and decrease variability in results.

New, advanced materials can sometimes be challenging to weld with conventional equipment. Differences in material compositions, strengths, hardness, and new coatings can increase demand on equipment and contribute to subpar results.
