Plasma arc welding machine with large energy density, directional arc strong, strong penetration ability. Compared with TIG, under the same circumstances weld penetration. Plasma arc welding is much faster.
Weld quality is not sensitive to changes in arc length. This is due to the proximity of the plasma arc cylindrical shape. Small heated area on the workpiece, narrow heat-affected zone, and thus a small plate welding deformation. And straight is good, the area on the heat spot is very small arc length variation, easily obtain a uniform weld shape. Particularly suitable for soldering micro precision parts.
