Thyristor CQ2/MAG semi-automatic welder
1.with the unitary function, preset the welding wire diameter, automatically match welding technics parameters.
2. automaticlaly shift to slow wire feeding to start arc, delivers excellent arc stability, no burst melt
3.suitable for all kinds of structural steel, alloy steel welding
