This machine is combined of auto-moving gantry, auto submerged arc welder, solder recycling system, guiding arc device etc. Using frequency variation can adjust the speed of welding moving. Using electric circuit control can get the result of stable arc, large range of current adjustment and the function of auto filling are pit. The machine is applied to the machinery manufacture, steel structure such industries.

Product main features
The control part is composed of MZK-3 welder control box and external control box.
MZK-3 control box uses the advanced electric circuit, having the advantage of large adjustment range of welding voltage current. It can adjust from 20V~50V, 200A~1000A. Using closed loop control can auto shifting feeding the wire. At the same time it has the function of auto guiding ARC and drawing back ARC.
