Hardfacing material is positioned in the crucible. A heating means for heating said crucible is positioned around the crucible and energized. A temperature sensitive primary control means for controlling said heating means is operatively connected to said crucible. A temperature sensitive secondary control means for controlling said heating means is operatively connected to the bearing pin ball bearing raceway flange. The primary control means is operative during the first portion of the hardfacing operation and the secondary control means is operative during the second portion of the hardfacing operation.
