Abstract
Apparatus, systems, and/or methods for weld wire preheating are disclosed. Some examples of the present disclosure relate to welding-type systems that use one or more preheaters to heat welding wire prior to an arc and/or deposition on a weldment. The welding wire may have one or more characteristics. A preheating control may determine a governing characteristic of the one or more welding wire characteristics and establish a threshold temperature and/or target temperature based on the governing characteristic. The preheating control may further control the one or more preheaters based on the threshold temperature and/or target temperature, in order to avoid a deformation and/or degradation of the welding wire that would impact column strength, wire feeding, weld process stability, and/or welding consumable longevity.
