    tig finger

    Other things to watch would be gas flow rate and cup size; maybe #6 at 6...

    Etching fixed

    Received the board and installed today. See before and after pictures. Works very well. The #5 or #7 refer to the gas lens cup size. Sequence was top to bottom. Thank you for fixing the issue.

    AC balancing

    Similar issues with fine tuning the AC process on thinner material. Etching a little wider than I like, but not critical for my applications. See "Aluminum Catch Cans" under projects for a picture....

    torch

    I had used the Weld Craft 20 for years; I had a lot of consumables and gas lenses. The CK 200 was half the price of the Weld Craft and the consumables are interchangeable.

    shielding

    I think he meant "behind the cup", which can draw air into the weld and contaminate your work. Also, the flow rate being to high can make this worse; maybe 5 to 7 LPM depending on your cup size. ...
