description
1. Technology parameter

It uses IGBT invert technology, stable output current, strong pressure-resist waving(V±15%)
It has electric reactor controller, stable welding course, small flash, deep liquid bath and wonderful shape.
It can adjust current and voltage separately. Changed one knob that can welder to choose CO2/MAG, and cooperate with other kinds of air automatic welding machine.
It is suit for welding 1.0mm and over steel plate
