Request 3D Model

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 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 0.482 IN
The refractory metal face is RWMA Class 14 (100% molybdenum)(ASTM B387 Type 360) which is typically used for resistance welding or resistance brazing braided or sold copper conductors to ferrous or nonferrous terminals, lugs or fittings.
