    What's the joint and joint prep? How physically big is it? I'm not picturing how it's not visible for you.

    A picture is worth a thousand words.

    If you were a Star Wars fan I'd say trust the force Luke.

    That said, If the machine is set to weld properly, not seeing it isn't as big a problem as you might think. Speed of travel is. Think of it this way... before you start you will divide the joint angle centering the gun. Start at the top and work down, again, speed of travel. You didn't mention the size of weld, or the filling required but if you catch the sides uniformly, your progressing down, speed of travel. Standing directly in front, as I suspect you are, the wire is your site, but it blocks your view, center it between the sides and again, speed of travel down. You mention not seeing the center, well, head off to the side, you should again hold a gun position to divide the joint, now see the back of the weld, edges on the side, and the "crack" below, and if the gun remains consistent, speed of travel down.
    Sometimes the "crack", seam, isn't apparent, high light it with a soap stone line, scratch it brighter with an awl, or a lighter shade of lens to look through in the helmet.

    All in, position the gun to the joint and with out a helmet, find what position allows for a good view and keep your head there. The trick again is hold the gun, electrode, torch to remain steady and move consistently, again, speed of travel.

    outside corner downhill

    Not sure what I’m doing wrong here. This position gives me fits. The problem is I can see arc and puddle, but everything else is total black, no way can I see where I’m going. I’m holding the gun horizontally with the tip perpendicular/slightly up, and pulling down,

    I know this probably has to do with head position, but I can’t seem to find the sweet spot

    Don’t have this problem with other positions, like if I’m welding the outside corner flat or horizontally, instead of downhill, the world is spinning on greased grooves

    Any tips on head position to see better?
Working...
