Abstract:
A holder for a consumable electrode used to cut metal by means of an electric arc is disclosed. The holder has an elongated barrel for containing the electrode and a pistol grip depending from the barrel for supplying electrical energy to the electrode. The exposed length of the electrode can be adjusted by a ram which slides in the barrel behind the electrode and which cooperates with clamping means actuated by a trigger on the pistol grip to secure the electrode at any adjusted length. Compressed air and electrical energy are supplied to the base of the pistol grip and are respectively communicated to a nozzle at the front end of the barrel and to the electrode. The nozzle is mounted for rotation relative to the electrode and has orifices for ejecting the air along any desired side of the electrode. Manifold means in the nozzle insures a continuous supply of compressed air to the orifices irrespective of the angular position of the nozzle. A metallic heat shield protects the nozzle from radiation, and a shield depends from the barrel in front of the pistol grip to protect a workman's fingers from excessive radiation.
