Aristo Mig 4004i Pulse

Aristo® Mig 4004i Pulse is an electronic controlled MIG/MAG/MMA lightweight inverter based welding power source, designed for high productivity and quality welding applications. BXA00166520.   The floor space (footprint) and the weight are reduced by 70% compared to conventional equipment. The new compact design combined with inverter technology has made Aristo® 4004i Pulse truly transportable.   Fan on demand cooling systems increase the welding time of the equipment. The cooling unit COOL 1 provides cooling of liquid-cooled torches to support great comfort to the welder. The cooling fans in the power source and the cooling system for the torch automatically turn off after 6.5 minutes inactivity, significantly reducing the idle time energy consumption. This 4th generation inverter offers considerable improved efficiency with a power factor better than 0.95. This gives you minimized energy consumption and will offer significant reductions in your energy cost with the same welding conditions.
