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 0.482 IN
The part mounts via a 4RW standard taper which is suitable for weld forces ranging between 200 to 800 pounds of force.
The B nose or Dome face tip is the most commonly used weldface because the design accomodates modest misalignment problems as contact can still be made on the radius during welding.
The weld face is 0.125 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.
