Abstract: A customizable portable generator system and methods for assembling the same. In one example, the generator system generally includes a universal frame including a plurality of mounting interfaces configured for detachably attaching one of a plurality of different engines and a plurality of wheel assemblies and/or support legs. Optionally, at least one handlebar assembly may be detachably mounted on the frame in at least one of two possible positions. In one example, the handlebar may be pivotably mounted to the frame. The frame components may be assembled into a kit from which a user may select various options to custom configure the generator unit. Other appurtenances and accessories may be provided which interface with the generator unit and frame. A modular generator frame and compressed gas-fueled generators are also disclosed.

Abstract: A welding power supply unit includes an outer enclosure having a plurality of sides that encompass internal components of the welding power supply unit. The welding power supply unit also includes a roll cage assembly having a plurality of roll bars. Each roll bar is disposed generally parallel with, but not adjacent to, an edge of a side of the outer enclosure and external to the outer enclosure. At least two of the roll bars are associated with handle portions that rotate with respect to the respective roll bar. Each handle portion includes an extruded tubular aluminum bracket or a die cast aluminum bracket disposed around its respective roll bar. In addition, the welding power supply unit includes a plurality of fastening mechanisms attached to the outer enclosure, the fastening mechanisms securing the roll cage assembly to the outer enclosure.
