ABSTRACT:
A welder comprises a source of electrical welding current. A housing houses the source and has front and rear walls and a top wall. A control device, for controlling a condition of the welder, is located along the top wall. A rear wheel is attached to the housing and has a portion located both rearward and downward from the housing. This enables the welder to pivot about the rear wheel between an upright position and a lying position. A front wheel and a foot are attached to the housing. In the upright position, the front and rear wheels engage the floor to support the housing above and spaced from the floor. In the lying position, the rear wheel and the foot engage the floor to support the housing above and spaced from the floor.
