TUFFALOY WELDER ARMS
Spot welding machine arms made by TUFFALOY reduce set-up time and give longer life.
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, (which are bulkier than simple straight 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 configuations are shown in the table. Special arms are also available.
