I was doing some practice welding tonight and I had what I thought was a good setting from picture number 3. You can see the wire I was using the picture number 1 and the gas settings in picture number 2.
Then I fabbed up a hanger for my ground and gun. I thought the welds actually came out pretty good (for me). Pictures 4 and 5.
While welding the bracket, the wire came off the drive wheel and shorted on the positive lug. Picture 6. I straightened everything up and welded some more on the bracket.
I went back to doing a little more practice welding and now it seems as no matter what I do, I’m blowing holes in the sheet metal. Picture 7.
I have the power on the lowest setting, A, and the wire speed at 3.5 like before.
So what’s causing the blow through‘s and it’s almost like the weld is frothing, for lack of a better word.
Did something happen when the wire shorted out?
Edit 1. I’m seeing what looks like a lot of brown residue, whereas I did not see that before or as much.
Edit 2. Hopefully the pictures post right side up.
