UNIVERSAL HOLDER ASSEMBLIES

Holders, Tee Connectors, and Adapters may be assembled

as shown, line by line in the table, to make up holder

assemblies that will do spot welding in many otherwise

inaccessible places. Goldcrown (ejector-type) holders

may be used in place of the non-ejector holders listed.

The Tee Connector is Class 3 RWMA alloy.

Electrode holder shanks can be attached to these arms from the front, by bolting the cap over them. This means no extra clearance is

required between the arms to allow running a shank up (or down) into a hole in the arm. It makes the insertion of Tuffaloy multiple-

welding holders much easier.

One of the most common failures of welder arms is the destruction of the bolt hole threads, due to the relatively soft copper involved.

Tuffaloy arms have a transverse steel bar insert in which the bolt hole

threads are cut. This provides greatly increased thread life.

Standard arm configurations are shown in the table. Special arms

are also available.
