    That machine can do both MIG and TIG. Which one do you do?
    I am an inexperienced welder, and for me TIG is easier when working with aluminum. Because I control the amount of added material by hand, I can more easily maintain the pool, so I am more confident that the weld is indeed strong.
    For checking watertightness, there are weld check sprays.

    (I hope I could contribute something. I know these are basic things.)

    That is an arrogant and unfounded opinion. Many of us have built hundreds of boats. Get your facts correct before insulting a large group of professionals.
