On new clean metal this is unlikely, and the acetone and IPA washes should remove any minor residue.

Still if the owner caught me doing this then I'd get an earful :x

If NASA specs it for "Man-Rated" vehicles, your dickhead boss has little argument against it.

Once again, you are correct , sir. :)

The washes are to remove dust left over from the Scotchbrite and oxidized Al. We do allow a few minutes time for both washes to evaporate completely and we are required (with good reason) to handle all cleaned parts with nitrile or cotton gloves.

It's definitely a worthwhile purchase. I bought one when Jody recommended it in a video. Lots of good info in it.

Nice little PDF books on basic overviews for each process.- if you can skip the pages and pages of safety
They had something called "TIG Handbook" 85 ish pages long PDF but only on the website chapter by chapter.

Hello

Is there a thread that collects all the links provided ?

Some forums allow to "pin" threads so they are always at the top.


ABout LIncoln documentation, I was surprised to discover many guides are free, you can order them (paper version ) free of charge (even outside USA in some countries apparently)

Best regards
