Non-Piloted Nut Electrodes are for welding nuts. The part has an insulated, spring loaded pilot that retracts when it makes contact with the upper electrode which prevents damage.

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 2.500 IN
  • The part mounts via a 5RW standard taper which is suitable for weld forces ranging between 800 to 1500 pounds of force.
  • The weld face is 0.625 IN
  • The part has a spring loaded insulated pilot for welding a 6 mm nut.
  • The diameter of the pin is 0.186 IN
  • The diameter of the pilot is 0.25 IN.
