For beginners in welding, the SYM function is very good (by default), but there is also a manual setting of parameters (apparently for the pros already).
Pros
I am new to welding and immediately had to weld the exhaust system on my car, it turned out, I welded it with a flux-cored wire. Hence the conclusion: it cooks well, it also tunes well, the workmanship is good.
Cons
There were 2 masses in the kit and there was no electrode holder, BUT the seller quickly responded and promptly sent the electrode holder - Respect to him for this.
