Function Characteristics: This kind of machine is used in single spot or many spots welding. Upper electrode and welding pressure could adjust at random, in order to make welding spots firmly, the electrode adopts efficient refrigeration system, so it makes sure that the machine works continuously; the switch of main return is composed of imported silicon, it has fast reaction and accurate parameter, so it makes sure that output current is stable. Use Of The Product: This machine welds mainly special mesh, such as mechanism, construction, the metal finished product, enclosure mesh, fence mesh, barbecue mesh, craft mesh, small sheet, stainless steel mesh, and mesh edge.
