Same for arc welding?
I loved reading your class throughout every section, and, although I already completed some small/medium size projects before, I learnt very useful tips and techniques.
However, in my opinion, it would have been nice to include something about arc welding techniques. Perhaps it should not be too different, but as arc welders are by far cheaper to buy (but harder to learn to use), people may feel more encouraged to follow your instructions if they could complete the proposed projects by spending less than 100 dollars (or euros as in my case). MIG welders are fantastic but expensive, and for hobbysts may not be the best choice.
Anyway, thank you for your fantastic job, I am enthusiast.
