Plasma welding machines are used for plasma arc welding or PAW, as it is popularly called. Plasma arc welding is an advanced version of the tungsten inert gas (TIG) welding process. Plasma welding machines enable performing high quality welding due to the use of high tech plasma welding systems.
Unlike TIG-welding torches, Plasma welding machines feature a constricting nozzle that enables two separate gas flows giving rise to a concentrated plasma arc having a narrow columnar shape. Additionally, the plasma column generated by the plasma welding machine is stabilized along the axis of the electrode and is much more intense than the TIG-welding arc.
Plasma welding machines offer much better quality of welding with lesser sensitivity to any changes in the arc length. Plasma welding machines require much less weld time and therefore result in less brittle welds due to carbides and other complex compounds.
If you're thinking about buying a welding machine for an arc welding process, you would do well to choose plasma welding machines from a reputed manufacturer that offers plasma welding machines that have been thoroughly tested and backed by some kind of performance guarantee. A plasma welding machine will be a good acquisition for your welding business.
