First off I appologise for being stupid! With that said, maybe with your help and a little practice I can get less stupid.

I am practicing with the Lincoln 225ac that I just got to weld the frame on my pickup. I am overlapping the frame to engineer a kickup. I am cutting small pcs. of frame rail (scrap) and welding them the same way the frame needs to be welded as practice.

The v between the two pcs. of frame rail is pretty deep, I tried to slow down and get more material into the v to build it up and I melted clean through the rail. I am assuming from this that I am going to have to run a good weld, then clean up the slag, and go back over it to "fill" the gap up? I am using a 1/8" 6013 rod at 135 amps. After I melted through the rail I backed it off to 120, but I didn't think it worked quite as well.

When I tested it to failure with the BFH the weld itself broke after bending it over 90 degrees, and not the welds grip on the frame rails, can I assume from this I got good penetration?

Thanks,
