The Migatronic MIG 445 is a transformer MIG/MAG welder for steel, with a current of 400 A at a 40% cycle and 265 A at a 100% cycle. You adjust the current in steps and the wire feed steplessly. The supply is 400 V.
What this machine is for
This is gear for simple, heavy welding of structural steel: frames, structures and repairs in the workshop. Continuous work up to 265 A means long runs with no wait for cooling, and 400 A at a 40% cycle you use on thicker sections.
The power circuit rests on a transformer with thick copper windings and a large fan, that is on a design that takes dust and mains swings. Adjustment in steps sets the voltage stages, and stepless adjustment of the feed matches the wire speed within a stage.
Features and equipment
- Transformer power circuit on thick copper windings: a simple and hard wearing design.
- Large fan: cooling of the components during long work.
- Welding current adjustment in steps with a stage switch.
- Stepless adjustment of the wire feed speed.

What to watch out for
The card gives liquid cooling, while the maker description speaks only of cooling, so confirm the configuration before you buy. Adjustment in steps means work on stages, without a smooth passage between them. The description does not list an earth cable or feed rolls, so ask about the equipment. The weight is not given, so plan transport in advance.
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.
