Abstract: An example welding-type system 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 via a second contact tip of the welding torch; a switching circuit configured to control a current flow between the welding-type power source and the first contact tip; and a preheat control circuit configured to control the switching circuit to: selectively direct current from the welding-type power source to the second contact tip; and selectively divert current from the electrode preheating circuit to the first contact tip.

Abstract: Systems and methods for cleaning a wire electrode after a welding process has ended are described. During a welding process, a wire electrode may be fed forward from a wire feeder through a welding torch to create a molten weld pool. While, conventionally, feeding of the wire electrode stops when the welding process ends, the present disclosure contemplates instead continuing to feed the wire electrode forward after the welding process ends. More particularly, the present disclosure contemplates feeding the wire electrode into the weld pool so that the wire electrode can be “cleaned” in the molten weld pool created by the welding process. The “cleaned” wire electrode end can be more easily used to establish an electrical arc at the beginning of the next welding process.

Abstract: 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.

Abstract: A welding operation is performed by moving or rotating an arc in a welding torch, and feeding a metal cored wire through the torch in a direct current, electrode negative welding process. The electrode may include one or more arc stabilizers. The welding process may be pulsed or non-pulsed. Moreover, the process may be used with a number of different base metals intended to be welded, such as thin plate, galvanized metals, painted metals, coated metals, and so forth.
Abstract translation: 通过在焊炬中移动或旋转电弧进行焊接操作，并且通过直流电极负极焊接工艺将金属芯焊丝馈送通过焊炬进行。 电极可以包括一个或多个电弧稳定器。 焊接过程可以是脉冲的或非脉冲的。 此外，该方法可以与许多用于焊接的不同贱金属一起使用，例如薄板，镀锌金属，涂漆金属，涂覆的金属等。

Abstract: Systems, methods, and apparatus to control weld current in a preheating system are disclosed. An example preheating power supply includes power conversion circuitry configured to output welding-type power via a first output power connector and a second output power connector, and a bypass path prevention circuit configured to prevent less than a threshold voltage applied to the first output power connector and the second output power connector from a different power supply from causing current to flow between the first output power connector and the second output power connector.
