The ESAB Aristo MIG 450 is an inverter MIG/MAG power source with liquid cooling, with the PUA1 panel and pulse. The maker gives 450 A at a 40% cycle and 360 A at a 100% cycle. The supply is 400 V.
What this machine is for
This is a power source for a station that works long and under load. A current of 360 A at a 100% cycle is enough for long fillet welds and multi run fills in structural steel, and the peak of 450 A you take on thicker sections. Liquid cooling takes the heat off the torch, so you hold the parameters through the whole shift.
The PUA1 panel runs synergic welding with a long list of curves, so changing over between material, gas and wire diameter comes down to picking a program. Pulse helps on stainless steel and aluminium, because it cuts spatter and doses the heat.
Features and equipment
- Inverter power source: a fast answer to changes in the arc and a steady penetration.
- PUA1 panel: program choice and parameter correction from one place.
- Pulsed welding: the pulsing arc orders the metal transfer.
- A long list of synergic curves for the material, the gas and the wire diameter.
- Liquid cooling: the fluid circuit guards the torch at high currents.

What to watch out for
A 400 V supply needs a power socket, and liquid cooling needs a check of the fluid level and of the tightness of the circuit before you start. The description does not list a wire feeder, a torch or cables, so agree the content of the set with us before you buy. The weight is not given, so plan transport after you have seen the unit.
How we sell used machines
This unit was checked in our service workshop in Krotoszyn with measurements to PN-EN 60974-4 and a load test. The price includes the first year of the basic service package: an inspection with cleaning of the machine and a validation measurement. Further years can be added. We ship across the European Union, collection in person by appointment.
