Abstract
Systems, methods, and apparatus to control welding electrode preheating are disclosed. An example consumable electrode-fed welding-type system includes a welding-type current 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; an electrode preheating control circuit configured to adjust at least one of the preheating current or an electrode feed speed based on the change in the contact-tip-to-work-distance; and a current interpreter configured to determine a change in a contact-tip-to-work-distance of the welding torch based on at least one of the welding-type current or the preheating current.
