The ESAB Aristo Mig LUD 450 is an inverter MIG/MAG welder for 400 V, liquid cooled. The description gives 450 A at a 40% duty cycle and 360 A at a 100% duty cycle, and you make the settings from the PUA1 panel.
What this machine is for
This is a power source for production and steel structures, where the welds are long and the settings are to come back on the next shifts. At a 100% duty cycle the machine holds 360 A, that is you weld without a break at high current, and you take the peak of 450 A at a 40% duty cycle, for example on thick sections and at a high melting rate.
The PUA1 panel gives access to a long list of synergic curves. You point to the material, the wire and the gas, and the system matches the voltage to the wire feed. The pulse mode tears off the drop in time with the current, so there is less spatter and less work left after welding, and on stainless steel and aluminium you keep the pool in check more easily.
Features and equipment
- Pulse to cut down spatter and for aluminium and stainless steel.
- Synergic mode with a long list of synergic curves.
- The PUA1 panel for making the settings.
- Liquid cooling, water cooled torch.

What to watch out for
The product record puts the machine in the current band up to 500 A and the description gives 450 A at a 40% duty cycle, so when you match it to your process keep to the values from the duty cycle. The 400 V supply needs a three phase socket, and the description gives no value for the fuse. The synergic curves work properly only with the wire and the gas they were saved for, and with another pair you correct the parameters by hand. With liquid cooling watch the coolant level and the flow through the hoses. The description does not list a torch, cables or a wire feeder, so confirm what the set holds before you buy, and the weight and the dimensions for the transport as well.
