Welding system torch rotates welding wire in conical shape

Weld Revolution® LLC has introduced the MA-400™ air-cooled machine torch system. This rotating arc welding system includes a 400-amp, 100 percent duty cycle SpinArc™ welding torch; control box; and control cables. The welding torch connects directly to all existing wire feeders and power sources.

The patented torch rotates the welding wire in a conical shape. Centrifugal force detaches the molten droplets and propels the weld metal angularly, creating a consistent and sound weld bead. The speed and diameter of rotation are adjustable for different applications. Out-of-position welding is made possible by the surface tension created by the high-speed rotation, holding the puddle in the joint.

The system employs solid, metal-core, or flux-core welding wires from 0.035 to 0.0625 in. dia. Any existing welding machine can be used, including simple CV power sources or advanced power sources using pulsed waveforms.
