Abstract: A hybrid welding power system includes: an AC/DC converter (101) to generate a rectified voltage from AC input power; a boost circuit (102) to generate a DC link voltage from the rectified voltage; an inverter (104) to generate a transformer input from the DC link voltage in accordance with a welding operation; an HF transformer (106) to receive the transformer input and generate a transformer output; a secondary rectifier (108) to rectify the transformer output to generate output welding power to be supplied to a weld output of the welding power system; and a battery power converter to couple a battery (112) to the DC link, the transformer (106), or the weld output to enable discharging of the battery (112) to the hybrid welding power system and enables charging of the battery (112) via the AC input, the DC link, the transformer (106), or the weld output in various implementations.

Abstract: A portable welding system casing includes front, rear, top and bottom portions. First and second side members can each have a plurality of fastening lug portions. The first and second side members may each have a recess so that the recess of the first side member receives a first perimeter edge of the front, rear, top and bottom portions and the recess of the second side member receives a second perimeter edge of the front, rear, top and bottom portions. A plurality of handle members can be coupled between associated fastening lug portions of the first and second side member. First and second foot members coupled to respective surfaces of the front, rear and bottom portions. The resulting casing has improved structural strength and rigidity.

Abstract: A system, computer-implemented method, and article for controlling a user interface of a portable welding system are described. An input signal receiver, operable on a processor, is configured to receive one or more input signals from one or more input devices. A display controller, operable on the processor, is configured to receive, input information based upon the one or more input signals. A display device is configured to display a user interface provided by the display controller, the user interface including a first portion including an adjustable value and a second portion including a non-adjustable value. The display controller is configured to highlight changes to the non-adjustable value based upon changes made using the one or more input devices to the adjustable value.
