360° ROTATION - The arbitrarily rotatable gun head can be applied to various sizes of carbon rods, adding strong operational flexibility and good accessibility. The tail air tube and adapter can be rotated while making it safe and easy to use without worrying about the risk of leakage. SPECIFICATION - Accepts pointed carbons 1/8"(3.2mm)To3/8"(10mm). Accepts flat carbons 3/8"(10mm)To5/8"(16mm). Compressed Air Pressure: 5.6kg/cm 2 .Flow Rate: 21cfm(0.60 3 /Min). Torch & cable weight: 7.11bs. HIGH PRECISION - When cleaning weld defects, the shape and depth of flow can be observed under the electric arc with high precision, which is highly efficient and reduces labor intensity. APPLICATION - It’s mainly used to groove, cut casting risers, clean weld marks, and clean weld defects. It is widely used in manufacturing, shipbuilding.
