Abstract: Systems, methods, and apparatus to preheat welding wire for low hydrogen welding are disclosed. An example apparatus to reduce hydrogen associated with a consumable welding electrode includes: a welding-type power 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 between a wire feeder supplying the welding-type electrode and at least one of the first contact tip or a second contact tip of the welding torch.
