          Electrode Selection Guide

          ELECTRODE SELECTION GUIDE
            The number which follows each material is the RWMA (Resistance Welder Manufacturers' Association) number of the electrode which would normally be placed against that material. For Example, when welding Alumel to Consil, a RWMA -2 electrode should be used on the Alumel side, and a RWMA -11 on the Consil side.   Not all combinations have been tried successfully.
