The term Hot Wire refers to special capabilities of a welding system wherein the wire feeding into the weld puddle is preheated before coming in contact with the welding arc.
The additional components that provide Hot Wire capabilities to a welding system (please refer to the illustration) include a special heating element that is mounted in close proximity to where the wire exits the wire guide, and a suitable power supply to provide controlled current to the heating element.
The selected preheating temperature of the wire can vary greatly and can actually approach the melting point of the wire. When the filler wire passes through a heating element as it travels from the spool to the weld puddle, the increased temperature of the
wire can affect the speed at which the wire melts.
While other characteristics of the weld puddle can be changed, the most important factor is that of a significantly increased deposition rate.
