For household needs on the farm or homemade products - that’s it, you don’t need to keep protective gas cylinders. For commercial use - not an option. Got pros: Good quality for its price, can be cooked tolerably in the absence of a protective gas environment. Cons below: It splatters a little at the beginning of the feed (before the flux included in the composition begins to evaporate), but this is not a disadvantage, but a compromise for this type of wire.
