Abstract: Disclosed is an electrode holder to be used in welding that has a closed-end structure that removes the gripping problems inherent with open-jawed “tong-type” electrode holders. The electrode holder contains a grooved hole that allows tighter clamping onto an electrode, easing the process of bending an electrode by hand. The electrode holder also has a comfortable handle covered by a sleeve that keeps the electrode holder cool to the touch, allowing a welding lead to be fed through the sleeve and connected to the electrode holder without removing the handle of the electrode holder.

Abstract: An arc cutting and gouging torch in combination with nozzle assemblies for suspending a carbon electrode and discharging a combined air stream relative to the carbon electrode centerline. The nozzle assemblies include exit orifices which are disposed in a non-parallel alignment relative to one another and the electrode to cause the air jet discharged from each exit orifice to merge at a location upstream of the arc and substantially about the centerline of the electrode.

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.

Abstract: A clamp for electrically connecting a part to be anodized to a conductive bar having a member adapted to attach to the bar and a frame disposed on said member for holding the part to be anodized. Electrical contacts within the frame are forced against the conductive bar and the part to be anodized in the clamped position.
