3.Stability
Long lifetime beyond your expectation.
4.Intelligence
All welding parameters can be adjusted through operating panel, to satisfy different weld conditions.
5.Cost Effective
ARC welders can save much more electricity than traditional welders, such as it can save 6-10 degree electricity after using each roll of welding wire. If each welder uses each two rolls of welding wire on each day, it can save 1000 USD each year.
