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. To return the battery tray to the closed position, it is lifted to pivot it about an angled strip on the second bottom wall until the first bottom wall is higher than the machine floor. Then the battery tray is pushed back to the first position, sliding the first bottom wall on the machine floor.
