    Mark, as a bonus, with those Tig machines you can weld with stick too;)...they are all CC(constant current) machines.

    Hey John,

    Do you have a chart of the general guidlines for TIG'ing certain metals & thicknesses??

    IOW, I was playing around with some 16G SS the other day & was having a heck of a time trying to figure out why I was burning holes through it. turns out I had too much current (duh, right....... LOL).

    If I had a chart of what thicknesses of what metals were "about" what current that would help a lot.

    thanks amigo
    Bob

    Silly question for John or anyone else that wants to chime in, will this loop be strong enough if I didn't have 100% penetration?

    Miller suggested > 200A for welding 1/4" thick material, I was working at 60A and blowing the breaker repeatedly. I have a good amount of penetration, but it was not going all the way through to the back. Will the amount of weld I have here be safe enough in the event of a driveshaft failure?

    I'll ask here first since this is the "welding" stickey. Has anyone welded a cage with a lincoln 180 mig? I need to play with it a bit more before I start welding the cage together, just wondering about anyone else's experience with this unit.

    OK guys, I Finally bought a welder. I found a Lincoln 140T for a price I couldn't refuse..........$449. I just bought my Ar/CO2 mix bottle and a cart. I just started playing with the welder. I have some 1x2 box steel I was welding. I don't have any pics right now. I know this is not a powerful welder, but for sheetmetal and mild fab work I think I sould be fine. I'm using .025 solid core wire right now. I'll post pics when I get home from work.

    Let me know what you guys think.........

    Here's what I have done so far......

    This is what I'm practicing on

    [​IMG]

    This is with solid core wire...

    This is with flux core wire. I think it penetrated better. I had to slow down the feed speed almost to one.
