Refractory metal tips are designed to withstand greater heat and pressure at the expense of some conductivity. They are used to spot weld high resistance base metals or to achieve desired heat balance when welding dissimilar materials, or for resistance brazing.

RMWA Class 2 (C18200) material - a copper, chromium material recommend for high production operations spot welding hot or cold rolled steels, galvanized and coated materials.

  • The overall length is 2.000 IN
  • The outside diameter is 0.875 IN
  • The part mounts via a 7RW standard taper which is suitable for weld forces ranging between 2,000 to 2,400 pounds of force.
  • The C nose of Flat face tip is frequently used as a backup electrode for projection welding, cosmetic welds, or to control heat balancing of the weld by controlling the current density.
  • The weld face is 0.875 IN
  • A refractory metal face made from 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.
