The Migatronic DynaMig 335 is a transformer MIG/MAG welder supplied from a 400 V mains, with gas cooling. It gives 335 A at a 35% duty cycle and 240 A at 100%. You adjust the wire feed steplessly and the welding current in steps.
What this machine is for
This is a small power source for daily work in a metal shop and in a repair workshop. A current of 240 A at a 100% cycle lets you pull long runs on sheet and on sections of medium thickness with no breaks to cool down, and the reserve up to 335 A you take on thicker fillet welds. The torch from the set is rated 300 A.
Adjustment in steps gives set stages that you write into a work sheet and repeat on the second shift, and stepless adjustment of the wire feed tunes the working point to the thickness of the material. This is gear with no screen menu, and you teach a new worker to use it in a quarter of an hour.
Features and equipment
- Transformer build: a simple design that takes dust and mains voltage swings.
- Welding current adjustment in steps: repeatable setting stages.
- Stepless wire feed adjustment: you match the feed speed to the thickness of the material.
- Gas cooling: simpler to run, with no fluid circuit and no coolant level to watch.

What to watch out for
The card gives a welding current up to 400 A, while the source description gives 335 A at a 35% cycle, so confirm the value on the rating plate. The torch from the set is made for 300 A and gas cools it, so on longer work above that value the handle heats up. A 35% cycle at 335 A means short stretches at the highest setting, and for continuous work stay with 240 A. A 400 V supply needs a power socket. The length of the earth lead and of the mains cable is not given, so ask about them before you buy.
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.
