WSEM-315,WSEM-400,WSEM-500
Features and suitable scope of products：
1、 High quality square wave current,speedy current transform, stable arc,no need to use HF in stabling the arc.
2、 Concentrated heat, solid arc,easy to fill in the wire, especially suitable for the aluminum alloy welding.
3、 Strong capability for clearing oxidation film,the clear width can be adjusted continuously and the welding seam is beautiful and bright..
4、 Use IGBT advanced inverter technology.
5、 Built in the over current,over heat,over voltage alarm and protecting circuit which ensure a more reliable and safe operation.
6、 Can meet the demand of butt welding,angle welding,etc.
7、 Widely used in aluminum,carbon steel,stainless steel,cooper and titanium welding,etc.
8、Manual welding, high and low frequency tig welding functions 2-in-1
