  • Publication number: 20250187095
    Abstract: A method of operating a hybrid power supply includes supplying to a power source, from a first energy source, power for a welding or a cutting process, selectively supplying to the power source, from a second energy source, supplementary power for the welding or the cutting process, and controlling an amount of the supplementary power that is supplied for the welding or the cutting process based on at least one of (a) a circuit breaker value of a circuit breaker arranged as a safety device in the first energy source (b) a voltage level presented by the first energy source, and (c) an output current setting of the power source.

  • Publication number: 20250178111
    Abstract: A method performed by a welding system configured to be powered by a battery to generate weld power to strike an arc for a welding or a plasma cutting operation includes: receiving a selection of a welding mode among different welding modes in which the welding system is capable of operating, to produce a selected welding mode; determining, for the selected welding mode, an energy consumption requirement that depends on the selected welding mode; determining a state of charge (SOC) of the battery and a battery energy from the SOC; determining a remaining amount of welding or plasma cutting that is supported by the battery energy based on the battery energy and the energy consumption requirement; and presenting an indication of the remaining amount for the selected welding mode.

  • Publication number: 20250170666
    Abstract: A hybrid-powered (HP) power source (HP power source) for a welding or plasma cutting system comprises: power inputs including an AC input for AC power and a battery input for battery power; an HP power converter to convert one or more of the AC power and the battery power to a weld power for welding or plasma cutting when the HP power converter is turned ON; and ON/OFF control circuitry including a user switch and which is coupled to the power inputs and the HP power converter, wherein the ON/OFF control circuitry is configured to turn ON the HP power converter upon actuation of the user switch while the HP power converter is turned OFF, wherein the ON/OFF control circuitry is configured to connect to the HP power converter whichever of the AC power and the battery power is or are present upon the actuation.

  • Publication number: 20240100617
    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.

  • Patent number: 11623295
    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.

  • Patent number: 10983684
    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.
