    摘要： A method for controlling a start of a metalworking operation. The method includes detecting an initial contact between a wire being fed from a welding apparatus and a workpiece and, in response to the detection, halting feeding of the wire from the welding apparatus. The method further includes activating a high energy heat source configured to heat a tip of the wire and resuming the feeding of the wire from the welding apparatus when the tip of the wire is heated by the high energy heat source to a plastic state. The feeding of the wire is resumed by measuring a force feedback from the wire contacting the workpiece. An apparatus for implementing the method is also disclosed.

    摘要： A contact tip assembly with a preheating tip comprises 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. The assembly also includes an electrode preheating circuit configured to provide preheating current through a portion of the welding-type electrode via a second contact tip of the welding torch, and a voltage sense circuit to monitor a voltage drop across the two contact tips, and the electrode preheating circuit adjusts at least one of the first current or the preheating current based on the voltage drop.
