Abstract
An example welding-type system includes: a welding-type power source configured to provide welding-type current to a welding-type circuit, the welding-type circuit comprising a welding-type electrode and a first contact tip of a welding torch; an electrode preheating circuit configured to provide preheating current through a first portion of the welding-type electrode via a second contact tip of the welding torch; a switching circuit configured to control a current flow between the welding-type power source and the first contact tip; and a preheat control circuit configured to control the switching circuit to: selectively direct current from the welding-type power source to the second contact tip; and selectively divert current from the electrode preheating circuit to the first contact tip.
