Abstract
Systems, methods, and apparatus to provide preheat voltage feedback loss protection are disclosed. An example welding-type system includes a welding-type power source configured to provide welding-type power 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 power through a first portion of the welding-type electrode via a second contact tip of the welding torch; a preheat feedback circuit configured to measure a preheat voltage; and an electrode preheat control circuit configured to: control the preheating power based on the preheating voltage; and control the electrode preheating circuit to reduce the preheating power in response to detecting an invalid preheat voltage measured by the preheat feedback circuit.
