Abstract
A combination arc brazing and welding electrode holder for use with welding apparatus for holding a pair of brazing electrodes in proper arc striking and arc maintaining relation or for holding an arc welding electrode. The holder has a pair of hinged handle parts swingable between an open and a closed position and each of the handle parts carries an electrode holding clamp. One of the holding clamps together with its power lead is readily removable from its handle part so that it may be attached to a work piece remote from the holder thereby to constitute a grounding lead for electric arc welding. The holding clamps are so constructed as to wedgingly hold a range of sizes or diameters of electrodes.
Claims18
A combination arc brazing and arc welding electrode holder comprising a pair of handle parts cooperable with one another for use either as an arc brazing electrode holder or an arc welding electrode holder, said handle parts being movable between a closed position in which said two handle parts are in closed side-by-side relation and an open position in which at least one end of said handle parts are spaced from one another, an electrode clamp carried on said one end of each of said handle parts, a power lead connected to each of said clamps, means in each of said handle parts for holding respective said power lead, one of said clamps together with its respective power lead being removable from its respective handle part, said holder being usuable as an arc brazing electrode holder when said handle parts are in their open position and when both of said clamps are carried by their respective handle parts so as to support a pair of arc brazing electrodes in proper arc striking and maintaining relation, and when said one clamp and its electrical power lead are removed from its respective handle part and when said handle parts are in their closed position so as to hold a single electric arc welding electrode and so as to be adapted for electrically grounding a workpiece to be welded.
A combination arc brazing torch and welding electrode holder comprising a handle having two parts pivotally joined together at one end constituting the rear end of the handle for swinging toward and away from one another between an open position in which the other or front ends of the handle parts are spaced apart and a closed position in which the handle parts are substantially together whereby both handle parts may be readily gripped by one hand, an electrode holding clamp secured to the front end of each of said handle parts, each of said clamps comprising a pair of hinged jaws pivotally movable toward and away from one another and a spring for resiliently biasing said jaws closed, each of said jaws having a hole therethrough for reception of an electrode, said holes being larger than the diameter of the electrode, the holes of one of said jaws being located at one distance from the hinge point of the jaws and the hole of the other of said jaws being located at another distance from said hinge point so that with the jaws opened and with an electrode inserted through both of said holes in said jaws said electrode is wedgingly clamped in said jaws upon said jaws moving toward one another under the bias of said spring thereby to securely hold the electrode in place, each of said clamps is made of electrically conductive metal and each has a suitable power lead secured thereto in electrical connection therewith, one of said clamps being selectively removable from its respective handle part for being clampingly secured to a work piece to be welded thereby to constitute a grounding lead.
A combination arc brazing and arc welding electrode holder comprising a handle having two parts, each of said handle parts carrying an electrode holding clamp, each of said clamps comprising a pair of hinged jaws pivotally movable toward and away from one another and a spring for resiliently biasing said jaws closed for gripping an electrode, each of said clamps having an electrical lead connected thereto, said leads being carried within the respective handle part on which its clamp is mounted, one of said clamps together with its power lead being removable from their respective handle part for attachment to a workpiece to be welded so as to constitute a grounding lead, and, when installed on its handle part, said one clamp being usable as an electrode holder for holding one of a pair of brazing arc electrodes and for supplying power thereto via its said lead.
