Nozzle Welders & Circle Burners

CIRCLE BURNERS OXY-FUEL
CWI manufactures oxy-fuel circle burners which are used to burn holes on the pressure vessels/pipes.Rb-2500 circle burner - is self-supporting with a manually operated magnetic base, and maybe 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 no bevel).

NOZZLE WELDERS
We have two models of nozzle welders covering a range from 1" to 50" od with rising & fall cam action to follow the curvature of a vessel or pipe. The machine can work with welding processes like MIG, FCAW, and SAW.
The machine is equipped with meters, torche angle adjustors, flux hopper w/gate valve, heavy-duty horizontal and vertical adjustment wire reel assy.(rw-1500 12" apools and rw-2000 - 60lb coils).
Rotation controls are solid states and provide clockwise and counter-clockwise rotation.
Model rw-1500 circle welder rated at 500 amps 100% duty cycle welding dia 4" to 18" (25 to 457mm) od. wire sizes .035 to 5/64 (.8 to 2mm) on 12" od spools
Model rw-2000 circle welder rated at 700 amps 100% duty cycle. Welding dia. 4" to 18" (25 to 457mm) od, wire sizes 1/16 to 5/32 (1.6 to 4.0 mm) on 60 lb coils
The 3-jaw spider chucks are designed 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. They are three sizes of 3-Jaw Spider Chuck models available, 8" to 16", 10" to 24" and 10" to 42"
