Circle Burners Oxy-Fuel CWI manufactures oxy-fuel circle burners which are used to burn holes on the pressure vessels / pipes. Circle burner - is self-supporting with a manually operated magnetic base, and may be moved around. The torch movement is controlled by a mechanical cam allowing it to adjust to the curvature of the vessel. The machine can cut diameters from 1 ½” to 42" beveled cut holes and 4" to 42" square cut holes (straight through no bevel).
Nozzle Welders: We have two models covering a range from 1" to 50" od with rise & fall cam action to follow the curvature of a vessel or pipe. The machines can work with welding process like MIG, FCAW and SAW. The 3-jaw spider chucks are design for use with Nozzle Welders RW-1500 and RW-2000 to help eliminate set up time by automatically centering the Nozzle Welder on the nozzle. By simply dropping the chuck into the nozzle, expanding the arms out, bolting the machine to the chuck, and then timing the cam you are ready to weld. There are three sizes of 3-Jaw Spider Chuck models available, 8 “to 16”, 10”to 24” and 10”to 42”.
