Multiprocess equipment; MIG/MAG, pulse MIG, MMA, TIG, Pulse TIG and Carbon Arc Gouging.

Reliable and smooth starts and ends supported by efficient Hot-start and crater fill functions

Efficient Man Machine Communication by the user friendly control panel U6 or AristoPendant U8

Wide range of pre-programmed synergic lines. AristoPendant U8 provide the facility to define and store customized synergic lines for any material or gas combinations Memory for 10 (U6) or 99 (AristoPendant U8) welding parameters

ESAB LogicPump ELP, secures automatic start of water pump by connection of a water cooled welding gun at the wire feeder or a water cooled TIG torch.

TrueArcVoltage System, measures the correct arc voltage value independent of the length of the connection cable, return cable or welding gun.

Dust filter to handle tough and dirty environment and avoid grinding-dust and metal particles inside the chassis

Robust and powerful AristoMig 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 LogicPump The patented ESAB LogicPump ELP, automatically starts the cooling water pump in the machine when a water cooled gun is connected to the wire feeders AristoFeed 30 or AristoFeed 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. AristoSelector is an efficient solution for applications which require a quick and easy exchange between 2 different wire dimensions or wire types. Connect 2 x AristoFeed to 1 AristoMig and the selector provides automatically power to the one in operation.

Flexibility
The power sources are optimised to operate together with the wire feeders AristoFeed 30-4 and AristoFeed 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 TrueArcVoltage 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.

AristoPendant U8 for advanced applications
AristoPendant U8 support a quick access to synergic setting. More than 100 pre-programmed synergic lines are available. Welding based on preprogrammed synergic data reduce the preparation before start to a minimum. The memory provides additional functionalities. The capacity to store up to 99 welding parameters which can be recalled when ever needed. A number of soft buttons with flexible functions provides direct access to Hot start, crater fill, 2/4-stroke etc.
