Silicon Rectifier Arc Welder

Silicon rectifier arc welder, Model ZX6-400, is a product from Power Tech Welding System. Scope of application and characteristics: ZX6 series DC arc welder is a novel, energy-saving welding power with three phases; this series welder sectionalises primary and secondary windings to set up leak resistance; uses primary tap to adjust current, so improves welder power to balance the three phases; reduces no load loss, uses three phases to do rectification; has many advantages like reasonable and simple design, easy operation and maintenance, low noise and high efficiency; and widely used in welding of low alloy steel, stainless steel, wearable steel, piling welding, etc. Specifications: control method – silicon (SCR); rated input voltage ±10% – 3-phase, 380 V; rated input power – 27 kVA; frequency – 50/60 kVA; no-load voltage – 45-70 V; rated output current – 80-400 A; rated duty cycle – 35/60%; insulation class – F; diameter of rod – 3.2-6 mm; unit dimension – 655 x 470 x 760 mm; weight – 148 kg; and cooling –
