Recently I was able to test out a dream tool for metal cutting. Thermadyne has just introduced a new heavy-duty line of plasma cutters, and I tried out the Cutmaster True Series Model 52.

Plasma arc cutting (PAC) is a thermal cutting technique widely used in manufacturing applications such as shipbuilding, aerospace, fabrication, nuclear plants decommissioning, construction ...

Past research has indicated that surfaces with plain fibers called "velvet" that lack feather-like branches can prevent about 50 percent of the secondary electrons from escaping into the plasma.
