Main Features:
1.Advanced inverter power supply saves energy;
2.Small in size and light in weight, especially suitable for outdoor mobile operation.
3.This welder inverts the 50/60Hz line-frequency current into high-frequency current of over 100Hz with large-power switching devices,which is treated with such technologies as rectification and topology,so the welder has constant current.The power conversion rate is over85%,so it is obvious in enemy saving.
4.Thrust current regulating function can solve adhesion electrode, arc breaking or splash phenomenon.Because of the depth of molten pool in different electrode and arc transition form is different, in the drip short-circuit instantaneous output current to enhance an appropriate value, can obviously improve the welding performance
5.With excellent dynamic performance,litter splash,and outstanding arc starting and drop let transition property.
6.With strong anti-interference ability,and small current fluctustion
7.Equipped with a remote-control box,so it is considerate in design and convenient in operation.
8.Suitable for welding of carbon steel,low carbon steel,and alloyed steel.
