Product Description
Product Description

ZX7-630 is a heavy industrial four module IGBT inverter dual station welding machine, with four module dual station design, and the current of each station can be adjusted independently without mutual interference; The double station parallel connection can output sufficient nominal current, especially suitable for electroslag pressure welding and carbon arc air gouging.



■Unique design of dual position welding, welding current of each position can be adjusted independently without interference.
■Duplex parallel connection can outout full nominal current, suitable for electroslag pressure welding and carbon arc gouging
■Automatic compensation for the grid voltage fluctuation;
Digital current display, exact presetting of welding current is available
