13MM ARC AIR GOUGING CARBON DC - Gouging electrodes designed specifically for the air carbon arc metal removal process which melts metal with an electric arc, then removes it  with a jet of  compressed air. These carbons contain a precisely formulated blend of carbon and graphite that produces the most efficient metal removal performance. They offer excellent arc stability, superior metal removal rates, uniform diameter and clean slag - free grooves or cuts.Available in a number of types and sizes, gouging carbons are ideal for a broad range of applications, such as creating U-grooves for weld joint preparations, removing old welds, gouging out cracks, cleaning and repairing castings, removing hard surface metal, and for rough machining.They gouge, cut, bevel, pierce or flush off any metal including stainless steel, carbon steel, manganese steel, chrome-moly alloys, gray, malable and ductile iron, copper, aluminium, magnesium and nickel alloys - fast precisely and economically.They are made for use in any type of gouging torches connected to a D. C. power supply and compressed air source. The amperage required depends on the electrode diameter; an electrode is usually selected to make grooves or cuts slightly larger than its diameter.FEATURES :Excellent Arc Stability Superior Metal Removal Rate Uniform Diameter Clean Machinelike Grooves or cuts Greater overall EconomyAPPLICATIONS :Machining U - Grooves for weld joint preparation Removing defective welds Cleaning and repairing metal castings Removing hard surface metal to facilitate repair Cutting non ferrous and other "hard to cut" metals Rough machining
