METHODS AND APPARATUS TO CONVERT WELDING-TYPE POWER TO WELDING-TYPE POWER AND RESISTIVE PREHEATING POWER

Abstract:

An example welding accessory includes: a weld input configured to receive first welding-type power; and power conversion circuitry configured to: convert a first portion of the first welding-type power to second welding-type power; output the second welding-type power to a weld circuit; convert a second portion of the first welding-type power to preheating power; and output the preheating power to a preheater.
