Hello. I am trying to buy a welding machine. So far, I have an old transformer from the 80's. But it's also a little worse than 400v and its size. What will you say about the welding machine as above? Does anyone know how she does? possibly a related model. A huge plus because it has a mig mage and MMA function. And recommend what transformer 400v or 230v inverter welding works better? And how about the quality of the weld? I have never had contact with an inverter under 230v and I have zero orientation of how such equipment works. In addition, I looked at the usual electrodes and have systems that do not stick to the cold elector, and how is it in this model? I would add that I need to farm, ie some fence to sleep, a trailer, sometimes some simple structures, sometimes something at the car, etc.
