A welding cart with a cable management system may include a frame, a shelf adapted to support a welding machine, a plurality of upright members, a plurality of wheels supporting the cart, one or more pairs of holders disposed on one or more sides of the cart, and a removable bar that may be releasably secured to the one or more pairs of holders. The bar may be releasably secured to the holders via a pin-and-hole mechanism and may have a hook adapated to hold welding equipment such as cables. The bar may be releasably secured to a first pair of holders disposed on a side of the cart or a second pair of holders disposed on another side of the cart. This system provides additional, easily accessible storage space for welding tools and accessories while still being compatible with a wide variety of portable welding machines.

Methods of sculpting a hard material. An example method includes providing a pulsed power apparatus comprising: an articulated arm; a pulsed power drill bit comprising two electrodes and coupled to the articulated arm; and a power generator coupled to the two electrodes. The method further includes positioning the pulsed power drill bit such that at least one of the electrodes contacts the hard material; submerging the electrodes in a dielectric fluid; and discharging a high voltage pulse from at least one of the electrodes such that the discharged high voltage pulse passes through the hard material.

A welding sled, comprising a support base comprising one or more attachment points for attachment of a wire supply support and attachment of a wire drive assembly; a plurality of rollers coupled to a bottom of the support base; and a brake configured to selectively brake the welding sled.

A self-contained track or wheeled welders' cart may be driven at a wheel or set of wheels and/or at a track or set of tracks by hydraulic wheel drive motor(s). The hydraulic wheel/track motor(s) may in turn be driven by high-pressure hydraulic oil provided by an electric-hydraulic pump motor driven by electricity that is generated on the cart by an internal combustion engine. The powered cart may be moved forward and backward via, for example, a radio or other non-wired-signal remote controller in communication with a drive system for the cart's electric-hydraulic driven tracks(s) and/or wheels(s) on the cart. Also, the remote controller may be in communication with a rack and pinion type steering mechanism, for example. Electricity created on the cart may be used also for a portable welding system carried on the cart.

Power system radiators and power systems having radiators are disclosed. An example power system includes: an engine; a generator configured to generate electrical power from mechanical power provided by the engine; power conversion circuitry configured to convert the electrical power from the generator to welding-type power; and a housing enclosing the engine, the generator, and the power conversion circuitry; and a radiator assembly configured to cool the engine and comprising a heat exchanger oriented substantially horizontally when the power system is installed.

The automated ride-on stud welder eliminates the fatigue and hazards associated with stud welding by having a motor which powers a hydraulic system and a set of tracks. A seat is coupled to the automated ride-on stud welder and controls are used to direct its movement. A bulk stud storage bin stores various types of studs. These studs are moved into position via a stud track that loads studs into the stud welding system that is attached to the gantry. In addition, there is a stud attachment mechanism for ease of attaching studs to a welding surface.

A method and an apparatus efficiently and reliably cut a steel frame. The cutting method includes locating a cutting torch apart from the steel frame held by a holding device in a direction along a cutting surface, moving the cutting torch from a cutting start position to a first cutting end position in a first feed direction perpendicular to a supply direction along the cutting surface, while applying a flame from a fire port of the cutting torch in the supply direction and supplying cutting oxygen to thereby cut a part of the cutting surface, stopping the cutting torch at the first cutting end position and thereafter cutting an uncut part by moving the cutting torch from the first cutting end position in a second feed direction opposite to the first feed direction.

A processing apparatus has: a light irradiation apparatus that irradiates a surface of an object with a plurality of processing lights; and a first change apparatus that changes a relative positional relationship between light concentration positions of the plurality of processing lights in a direction that intersects with the surface of the object, the processing apparatus changes a thickness of a part of the object by irradiating the surface of the object with the plurality of processing lights.

A weaving control method in fillet welding. On a surface perpendicular to a welding direction, a position of the welding torch is set such that a weaving reference line passes through a base point on a weld line, and at least five fixed end points are set, and positions of the fixed end points are set such that one or more of the fixed end points are provided on each of both sides across the weaving reference line and a reference end point a being on the weaving reference line and having the shortest distance between a tip and a base metal is provided. The weaving operation is performed such that the welding torch moves between the fixed end points along with a trajectory forming a polygon when viewed from the welding direction.

Provided is a configurable handle for a work equipment. The work equipment, which may be a welding power source, can comprise a body, and a power conversion circuitry within the body. The power conversion circuitry is configured to convert input power to welding-type power. The work equipment comprises one or more handles attached to the body for physical manipulation of the work equipment, where at least one of the handles is configured to be oriented to any of a plurality of different positions.
