Really helpful post—finally a clear explanation of the difference between UONI rutile and UONI basic electrodes. I ran into this exact issue recently on a mixed welding job. Ended up using UONI basic for the heavy-duty parts and UONI rutile for the easier stuff. The arc behavior and slag were just like you described.
Also, after welding, I used a ceramic-polymer coating service from https://spb-angar.ru
. Everything went smoothly—the team was easy to work with, the coating turned out great, and they even gave me a small discount. Nice that they work with both individuals and companies too. Definitely recommend if you need a solid protective finish.
