NB Crystal gate tube control CO2/MAG semi-automatic gas protective welder

Mainly used carbon steel and low alloy steel and high-strength steel and other ferrous metal welding, to various welding positio

Introduction:

1.        Mainly used carbon steel and low alloy steel and high-strength steel and other ferrous metal welding, to various welding position, welding and high efficiency.

2.        Welding arc stability, the welding electric arc stability, auto-compensation to the electric network voltage.

3.        Solid core/drug core welding wire conversion and arc-receiving function.

4.        Deep weld penetration, less splash, easy performance and perfect welding line.

5.        Dual-drive wire feeding with the function of the NB-630 welder.
