Abstract: Systems and methods for auto-tuning a MIG welding process are disclosed. A welding-type power supply may include a power conversion circuitry configured to convert input power to welding-type power; and a controller configured to control the power conversion circuitry based on a plurality of operating parameters. The operating parameters may include an inductance parameter, a slope parameter, or a wet time parameter. During the welding process, in order to control the power conversion circuitry, the system may measure an output from the power conversion circuitry, and may update the inductance parameter, the slope parameter, or the wet time parameter.

Abstract: Submerged arc welding torches and systems to resistively preheat electrode wire are disclosed. A disclosed example submerged arc welding torch includes: a first contact tip configured to transfer weld current and preheating current to the wire; a second contact tip configured to conduct the preheating current to the wire; an air-cooled first conductive body portion configured to receive the weld current and to conduct the weld current and the preheating current to the first contact tip; an air-cooled second conductive body portion configured to receive the preheating current and to conduct the preheating current to the second contact tip; and an insulator coupled between the first and second conductive body portions.
