An engine-driven welding power supply, comprising a frame, an engine attached to the frame, and a generator attached to the frame. The generator is driven by the engine and configured to output electrical power via an electrical receptacle. Weld power conversion circuitry is integrally attached to the frame and configured to output welding-type power. A power conductor configured to provide input power to the weld conversion circuitry is configured to be manually coupled to the electrical receptacle or to an external source of electrical power. The weld power conversion circuitry is configured to convert the input power received via the power conductor to welding-type power.

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.

The invention relates to a welding assembly for the permanent joining of a first tubular component with a second component along a two- or three-dimensional intersection curve, along which both components contact, comprising a securing assembly for detachably securely joining on a tubular end of the first component facing away from the intersection curve, a manipulator unit mounted directly or indirectly on the securing assembly such that it can pivot about a tube longitudinal axis assigned to the first component. The manipulator unit has a freely positionable manipulator end, with a welding tool attached to the freely positionable manipulator end. The securing assembly comprises a clamping module that can at least partially be introduced into the tubular end of the first component on the end side and in an axial manner. The clamping module is detachably securely to a tube inner wall of the first tubular component, as well as a carrier ring module which is rotatably attached to the clamping module, which axially extends beyond the tubular end of the first tubular component.
