METHODS AND APPARATUS TO PROVIDE WELDING-TYPE POWER AND PREHEATING POWER

Abstract:

An example welding power supply includes: power conversion circuitry configured to convert input power to wire preheating power, and to output the wire preheating power to a preheating system; and control circuitry configured to control the power conversion circuitry based on a temperature model to preheat an electrode wire to a target temperature via the preheating system.
