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 0.625 IN
The part mounts via a 5RW standard taper which is suitable for weld forces ranging between 800 to 1500 pounds of force.
The A nose or Pointed face tip is a general purpose weld face suitable for most spot welding applications.
The weld face is 0.25 IN
The refractory metal face is RWMA Class 13 (100% tungsten) which does not alloy appreciably with non-ferrous materials. Therefore, it is commonly used for cross-wire welding of materials such as copper and brass.
