I had a one-week welding course in training about 15 years ago. Since every five years once welded point. With this device I could weld relatively well after only 15 minutes, even in the purely Auspuffendtopf previously welded (by myself) holes, I could then welded closed again. The default backup in the garage is kicked out not once, but had only the lowest amperage taken (for 1.6 electrode). Anti-stick effect usually works very well.
