ABSTRACT:
A magnetically-actuated switch adapted to control a welding device. The magnetically-actuated switch may comprise a set of electrical connectors that are brought into electrical communication with one another by magnetic force. The magnetically-actuated switch may be disposed within a welding implement coupled to the welding device. The welding implement may be operated by disposing a magnet proximate to the welding implement to actuate the magnetically-actuated switch. The magnet may be disposed within a magnet holder securable to a hand.
