ABSTRACT:
The controller automatically and remotely controls the stopping and running of an internal combustion engine coupled to a DC generator that supplies DC power to the welding cables of an arc welding machine. The engine has a starter, an ignition, and an intake manifold. A vacuum-actuated switching means is coupled to the intake manifold and is responsive to the vacuum produced therein. A switching circuit is coupled to and is controlled by the vacuum-actuated switching means. A starter and an ignition are coupled to the switching circuit. A timer having a predetermined timing interval is coupled to the switching circuit, to the welding circuit, and to the ignition.
