Weld Revolution Rolls Out MA-400TM Machine Torch System
The new MA-400TM air-cooled, machine torch 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 for a quick upgrade.
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, resulting in a phenomenon that holds the puddle in the joint.
The system employs solid, metal core or flux core welding wires ranging from 0.035 to 1/16 inch in diameter. Any existing welding machine can be used, including simple CV power sources or advanced power sources using pulsed waveforms.
Productivity and quality benefits are found in applications such as narrow groove welds, pipe welds, clad overlay, square butt joints, high-speed fillet welds, hard banding, and others. The rotation produces exceptional sidewall fusion, allowing narrow grooves to drastically reduce welding time and materials. In many cases, the weld joint can be modified to reduce or eliminate beveling altogether. The stirring action agitates the molten weld puddle, producing a better weld with enhanced properties. 832.585.1244, www.weldrevolution.com
