HYDRAULIC WELDERS HW 220 - HW 300 - HW 400 With sockets for single-three-phase generators Welders features low noise hydraulic motors with helicoidal gears HW 220 - HW 300 - HW 400 are professional DC hydraulic welders with power respectively of 220, 300 and 400 amps standard, other configurations on demand. This products can also be used as tri / mono phase current generators. They can be powered by the hydraulic circuit of excavators, trucks, mobile workshops and by all machines equipped with a suitable hydraulic circuit. Hydraulic offers numerous advantages: quietness, safety, versatility, easy transportability, robustness, absence of vibrations, no exhaust or smokes and minimal maintenance requirements, thanks to these features the welding machines increase the versatility of the machines, improving their efficiency and productivity. Ideal in any welding work outdoors and where it is necessary to have electricity everywhere and at low cost. Welders features low noise hydraulic motors with helicoidal gears.
