Abstract: A hydraulically driven welding machine employs a closed loop control system for maintaining a constant speed of a generator. A feedback device produces a controlled frequency proportional to the actual generator frequency. The controlled frequency is compared with a reference frequency preset in the machine. Any error between the controlled and referenced frequencies is used to control a proportional flow control valve to regulate the flow of hydraulic fluid through a hydraulic motor that rotates the generator to maintain a constant generator speed under varying welding conditions. The source of the hydraulic fluid may be a hydraulic system of a motor vehicle. In an alternate embodiment, an adjustable orifice produces a pressure drop in the hydraulic system. A change in generator speed changes the pressure drop. The pressure drop is used to control a valve that diverts the proper amount of fluid flow to the hydraulic motor to maintain a constant pressure drop and thus a constant generator speed.

Abstract: A battery tray for an engine-driven welding machine has two bottom walls separated by a step. When the battery tray is in a closed position, a battery retained on the battery tray is concealed inside the welding machine and the first bottom wall rests on a machine floor. To expose the battery, the battery tray is pulled out an end panel of the welding machine, sliding the first bottom wall on the machine floor until the step is at an outer face of the floor. A slight further pull causes the battery tray to drop the distance of the step such that the second bottom wall contacts the floor. Releasing the battery tray causes flanges on it to abut the machine end panel. The battery tray step and the flanges cooperate with the floor outer face and the machine end panel, respectively, to cantilever support the battery tray outside the welding machine.
