Look at the price of this product! If you believe that you get what you pay for in this world, this book is not for you. It's just too light in useful information on TIG welding. It's totally outdated with photos of antiquated machines and it gives little information on the techniques of TIG welding. In essence it reads like an introduction to TIG welding with only 77 pages (many of which consist of test questions) dedicated to this subject. Even used at $34, it offers less insights than the free information you can find online. Yes, it's a good introduction to TIG, but no, it's not worth the cheapest price you will buy it for. Keep hunting for something better.
