Plasma welding machines melt areas with an arc and then use a high-velocity, high-temperature ionized gas to make welds. The process of plasma welding is used to bring better control to the arc ...

It can weld most metals, even dissimilar ones. Plasma arc welding is a close relative of gas tungsten. Although scientists had been working on plasma for welding applications since the early 1900s, it ...

For instance, ESAB celebrated its 120th anniversary by touting its latest technology offerings in areas like submerged arc ...

The welder he’s working from in this project uses low-voltage alternating current to drive the welding process, but since a plasma cutter ionizes gas it needs high-voltage direct current.
