Electrode Adapters

Tuffaloy Electrode Adapters Header

Electrode Adapters are used to improve electrode holder life and flexibility by allowing the adapter to be replaced when the taper wears out. The standard electrode adapters are made from RWMA Class 2 alloy. Other Alloys are available upon request.

Electrode Adapters can mount to a holder via threads or RWMA tapers.

Electrode Adapters designed for use with Muti-Spot Barrels have an o-ring to prevent leaking.
