Abstract
It is described a grounding terminal for temporary fastening a grounding conductor to a construction to be welded. The grounding terminal uses permanent magnets, example given of neodymium (Nd—Fe—B-35) to fasten the terminal to the construction. A welder that uses the grounding terminal can by one grip easily scrape the contact surface of the construction free of paint, rust and oxide scale and thereafter fasten the grounding terminal to and unfasten it from the construction. Fastening and unfastening is based on relocation of the permanent magnets in such a way that an open and a closed magnetic loop respectively, are created.
Claims14
A magnetic grounding terminal for temporary connection of a grounding conductor to an object to be welded, said grounding terminal comprising
- (a) permanent magnet means for attracting the object by magnetic force;
- (b) housing means for accommodating the magnet means in the grounding terminal in either of two states, a first state in which the magnet means are arranged so that the grounding terminal fastens to the object by magnetic force and a second state in which the magnet means are arranged so that the grounding terminal unfastens from the object;
- and
- (c) switching means for permitting the magnet means to be switched from the second state to the first state by pressing the grounding terminal against the object and from the first state to the second state by pulling the grounding terminal away from the object, said switching means being manipulable with one hand whereby the grounding terminal can be fastened to and unfastened from the object with one hand.
