Abstract
A welding ground detection system and method are provided. In one embodiment, a switch actuator is interconnected to a grounding device and operatively associated with a switch. The switch is electrically connected to an electrical circuit that is operatively associated with the welding equipment. The switch is normally in an open state in which the switch opens the electrical circuit, thereby preventing welding. Upon connection of the grounding device to a workpiece, the switch actuator actuates the switch to a closed state, thereby permitting welding. In one embodiment, detection of a voltage, a current, a resistance, or an impedance of a ground connection is not required to actuate the switch.
