Features:
    Currently,sewing welders are mainly applied in molding welding overlapped edges of metal pressing facilities.
    The alternating current sewing welder-FN sewing welder is mainly applied in welding low carbonsteel utilities and stanless steel without plating.
    While the direct current sewing welder-ZFN sewing welder is a kind of secondary commute one. Comparing with alternating current sawing welder,ZFN needs smaller capacity due to its great improvement of power factor,which makes it energysaving product. It can be applied in wellding aluminium, titanium and plating steel besides the standard low carbonsteel.
