ABSTRACT:
An automatic welding turntable for welding together the cut-apart halves of a reconditioned torque converter is tilted to cause the bead of weld to fill the crack between the halves of the torque converter. A motor rotates the torque converter in a first direction while wire is fed to the stinger of a wire-fed arc welder. A sensor and a control circuit cause the torque converter to rotate 360.degree. plus a predetermined increment, stop welding, counter-rotate the predetermined increments, and shut down so that the turntable is set up to complete the next weld of 360.degree. plus the predetermined increment.
