HELPFUL SUGGESTIONS

The basic materials in all Tuffaloy electrodes are produced to rigid standards of quality and uniformity. The superior performance of these electrodes in your plant depends upon their correct application to the particular job, and proper maintenance in service. Many factors affecting electrode cost and useful electrode life are briefly outlined below.

PART TO BE WELDED

Layout the part for resistance welding. Designing engineer, welding engineer and production man in charge of welding should cooperate in securing a better product at lowest cost.

Correct design permits the use of standard straight electrodes; or standard offset or standard angular holder if the straight approach is not possible. Special shaped electrodes cost more, and the difficulty of cooling the electrode is amplified. Single spot, multiple spot, projection, or other method may be accurately chosen to achieve lowest cost. Consult the R.W. M. A. Manual.*

MATERIAL TO BE WELDED

The weldability of the materials can be determined by consulting your material supplier, and by reviewing recommendations covered in the R.W.M.A. Manual.* Surface conditions, rust, oil, dirt, and, on many articles, oxide film and even handling marks have a decided effect on weld quality. Cleaning may have to be part of the welding job in some cases.

WELDING EQUIPMENT AND CONTROL

A welding machine of reputable quality, purchased for a particular application will be correctly designed both electrically and mechanically, and will be supplied with the correct control equipment and electrodes for the work. On machine change-overs make sure of adequate electrical and mechanical capacity, and see that the necessary controls are provided. Consult us when redesigning or revising your choice of electrodes.
