Dual Shield.

The weld over slag I am referring to starts at 14:40. He was definitly good at the beginning, but this large gap he is filling at 1440, wouldn't that be over cold or hardened slag? When he goes in one direction the weld get dark (Cool in my eyes) and then he comes back over it.

I must have missed that part. I personally would never weld over slag. I've worked at places that would fire you in a New York second for doing that!:thumbdown:

Does any ones like innershield. ? Don't care for it to much to smoke and it's a pain to get it to run right.

Try some Lincoln NR-212, or Hobart 21-B. Before the Northridge earthquake in California we ran a lot of the Hobart 21-B. It also runs really good on galvanized steel. I've taken numerous 1-inch thick V-butt tests, 3-G, and 4-G with 21-B. Never failed one.

Oh I forgot to mention. Both those welds were made with a CC only 50-year old engine drive welder, and LN-25 wire feeder. Innershield will run better on a CV welder.

I ran some at the job site 13 years ago the wire must of been damp we try everything that day it would not run good at all!.

After the Northridge earthquake all structural welding on the west coast went to T-8 wires. Like Lincoln's NR-232, NR-233, and ESAB's Coreshield 8. Those wires are a lot harder to run than T-11 wires, like NR-212, and Hobart 21-B. With the T-8 wires you cannot vary the stick out at all!

And the wire has some pretty good specifications to it also! :thumbsup:
I think this wire would work great in the average home owners Mig welder.

Should this deal with impurities better than soild MIG wire?

Don't really know, but I would sure think so.

I am blaming you for making me spend more money.
