Abstract
Welding wire preheating systems and methods are disclosed. An example welding method includes: receiving a signal indicative of initiation of welding process; prior to initiating a welding arc based on the received signal, controlling voltage or current applied to a welding electrode to preheat the electrode to a temperature above an ambient temperature but below a melting point of the welding electrode; monitoring feedback voltage to determine a termination of preheating; and terminating preheating prior to initiating the welding arc in accordance with a welding protocol.
