抽头式电路经济实用，可靠性较高，维修简单，采用高压引弧，慢送丝极易引弧。熔深大、飞溅小，焊缝成形良好。

MIG/CO2 Series Gas-Shieding Welding Machines-NBC inside;

1,Adopt the three-phase bridge type rectification power source technology,has the reactance compensatory function,the current output is steady,little splash and smooth weld appearance.

2,Control loop uses integrated circuit,welding current is centralized,semi-automatic welding speed is rapid,with high effciency ,energy-conservation is remarkable,

3,Wire feeder insede,occupy

4,Suitable for welding
