Found electrodes from the USSR 30/40 years of storage How is it cooked? 

We managed to get hold of electrodes made during the Soviet era. I remember these electrodes well, since I myself began my career with just such, there were simply no others in those days. It’s a pity that all the specimens were rutile coated, I wanted to try the basic coating. But it may be possible to get them in the future.
Of course, there were no inverter machines in those days. Sources that produced direct current were very rare. The bulk of the welding machines of that time produced alternating current and, accordingly, electrodes with a basic coating, and it was simply impossible to use these SSSIs.
But with shipbuilding and ship repair, advanced technologies of that time were used, and just at these enterprises, most of the sources worked on direct current and the main electrodes were SSSI. Sheet metal was welded with automatic submerged-arc machines. We called them a tractor ... The seams turned out to be very even and beautiful ...
There were also very professional welders who made very beautiful and high-quality seams in all spatial positions. They had a personal stigma and paid extra for it. And then we were still young welders envied them very much.
