    OK, I get it now: this is one of your earlier tries.

    One of my first ever welding projects was a cargo rack, and the welds were not too good looking. Over time I got better and every time I used that rack I cringed at the sight of the welds. Finally I ground them out and re-welded it because I couldn't stand looking at them.

    Sling, Today I spent more time with the grinder than with the gun in my hand, however,, I did increase the wire feed speed from 4 to about 5.5. This made for a more consistent arc. I also left the cover on the gun. The wire exposed was less than half an inch. Visibility is still a bit of a problem.With the arc going I have a difficult time seeing the seam that I am attempting to weld. I have my helmet set to the lowest setting. Thanks, Ken

    You're going to find flux core wire makes it harder to see due to all the smoke from the flux burning off. Not that you can do much about it though. You might try to use a small vacuum to suck off some of the smoke. Not so much that it pulls the shielding gas the flux creates though. Less smoke means more visibility.

    Grinders happen to the best of us! But reading between the lines, it does sound like you're making progress because you're watching the weld as it happens. CTWD of 1/2" is spot on. Cover on or cover off turns out to be optional per the 115v Fluxcore Tips video I linked earlier, but protect the threads.

    Keep us posted!

    Well another chapter for the archives of welding history.My frame or table top is near completion.Just a few more clean up welds. Today clear progress was achieved. I literally held the tip of the gun onto the area to be welded.I actually surprised myself.WOW! However viability is not an issue but a hindrance. I am able to see the weld however I have to move the gun where I think I have to go.I do not think this is right.Tried using a fan to remove the smoke. Zero effect.I may have to look into another helmet.I have tried all different setting but have had all negative effects.Now to my local supplier and get the legs. I plan to use 1/4 x 2 in square tubing. Please go easy on me, Ken
