A device for welding with contact electrodes comprising a core having a metallic coating, includes an electrically insulative body with an outwardly extending handle. A metal chuck extends axially of the body and holds the electrode. A Ushaped frame has arms slidably inserted in the body and held by an adjustable clamp. A block slidable on the free ends of the arms is urged by springs toward the free ends of the arms. The block carries a removable cylindrical shroud for the electrode which extends through the shroud. An electric cable extends into the body and connects with the chuck. Interchangeable shrouds have differently shaped ends to conform with differently shaped surfaces of work to be welded.
Rods
Carbon rods
The carbon rods are used for arc air gouging,gouging out cracked welds,alot faster than grinding.Very good for cutting out old welds,so a part can be used again.
