Optimum welding solutions
Robust and powerful :
Aristo Mig U400 and U500 are ideal partners when it comes to efficient production or prefabrication of high alloyed materials with a very high demand on the welding performance.

The power sources are compact and sturdy pieces of equipment with a chassis made of extruded aluminium sections: Alutech™. This is a robust material that withstands rough treatment.

The power sources are based on inverter IGBT technology that provides reliable equipment with outstanding welding characteristics. The control and communication CAN-bus system means less cables, which in turn increases operational reliability.

ESAB Logic Pump The patented ESAB Logic Pump ELP, automatically starts the cooling water pump in the machine when a water cooled gun is connected to the wire feeders Aristo Feed 30 or Aristo Feed 48. This eliminates the risk of over-heating the welding gun. When a self-cooled gun is used, the pump is automatically shut off giving lower noise and longer lifetime for the cooling pump.

Aristo Selector is an efficient solution for applications which require a quick and easy exchange between 2 different wire dimensions or wire types. Connect 2 x Aristo Feed to 1 Aristo Mig and the selector provides automatically power to the one in operation.

Flexibility :
The power sources are optimised to operate together with the wire feeders Aristo Feed 30-4 and Aristo Feed 48-4. Connection cables up to 35 metres provides a working radius of up to 35 metres to suit all your individual welding needs.

The True Arc Voltage System, in combination with an ESAB PSF gun, guarantees that you weld with the correct arc voltage independent of any voltage drop in the welding cables. This means that you will get the same arc voltage and weld result either you have a set-up with short connection cable and 3 m gun or a set-up with 35 metres working radius.
