The Chameleon Max-Life Nut Electrode is a flexible solution designed for projection welding nuts. The weld head and insulated, spring loaded pin can easily be replaced after excessive wear to reduce tooling costs. The air port can be used to blow slag away from the weld face and pin after each weld.

A refractory metal face is made of RWMA Class 11 (75% tungsten, 25% copper) (ASTM 702 C1D) is brazed onto the base material. This face is typically used for welding at higher pressure and heat common with projection welding.

  • The overall length is 2.875 IN
  • The weld face diameter is 0.625 IN
  • The part mounts via a 5RW standard taper which is suitable for weld forces ranging between 800 to 1500 pounds of force.
  • The part has a spring loaded insulated pilot for welding a 4 mm nut.
  • The diameter of the pin is 0.187 IN
  • The part has a 1/16 NPT threaded port for an air line
