Twin submerged arc automatic welding is a kind of high efficient welding process, with higher deposition rate and easily getting reasonable weld seam and good quality under high speed.
The wire mutually radiated which makes higher energy utilization, thinner molten drop, move stable welding process, and perfect bead shape.
With deposition rate increased, low heat input can be still remained to assure joint mechanical performance and reduce the welding distortion.
Digital display, easy for reading.
The short circuit protection function prevent PCB damage from internal short of control cable or short between control cable and welding output cabel.
