Main Feature

1.Suitable for most metal welding,it can be used as gas welding and mma welding,portable and        energy saving.

2.Welder volume is smaller and more portable.

3.Energy efficient double zero soft-switching IGBT inverter technology, inverter frequency is up to  20KHZ, It reduces the inverter switching losses, greatly improving the reliability of the inverter, It can  save electricity up to maximum 28%.

4.Closed duct design,strictly follow the IP21 protection grade design,superior dustproof  performance,through the metal, mist, dust, soil dust experiments to enhance the outdoor work  protection,the product is suitable for most work environments.Key components adopt imported  products,circuit boards and other key parts adopt three anti-treatment,more durable,more reliable.

5.The design of whole mechanical structure is reasonable,robust and reliable, adapt to transporting,  moving work environment, which can effectively prevent the collision damage.

6.The machine designed double integral electronic reactor circuit and the time constant (inductance)  regulating circuit for short circuit transfer mode,optimizing and controlling the welding process of  short circuit transfer.Double CPU operation made it excellent welding characteristics,and the stability  of the arc has precise control.High arc reaction rate and good trackability.Compared with SCR  welder,it is less spatter and better weld,excellent weldability.

7.It has a "close arc function" ,suitable for long seam welding

8.It has the function of cutting solder ball after welding,removing the droplet beads at the end of the  wire,Supplemented by high idling and slow wire arc program, improving the success rate of the first  arc.

9.It can do co2 welding and mag welding.

10.Excellent output current ability,adapt to Φ0.8-1.6 welding wire,cable length can be extended to

 30 m to weld.
