This is an excellent book for beginners and more experienced guys alike. I like that it has other tips and shop techniques. Helpful for a mechanic who's fooled around with a Mig welder, but could use some pointers and science-y explanation to refine my skills. The book does seem a little dated, and the author seems to be from the UK, so sometimes his phrases and colloquialisms don't make much sense to an American reader, but this information is solid and helpful. Recommend.
