Abstract
An auxiliary welding heating system includes an induction heating coil disposed adjacent to a welding torch or plasma cutter. The auxiliary welding heating system further includes an induction power supply configured to generate an alternating current and a step-down transformer coupled to the induction power supply. The induction heating coil is coupled to the step-down transformer and is configured to receive the alternating current and induce eddy currents in a welding work piece to heat the welding work piece before an advancing welding arc or plasma cut to a homologous temperature of at least approximately 0.5.
