here is my second day welding mild and stainless, my brother is a welder and was giving me lots of tips.. wanted to see if you guys have any as well.
miller 185sd, ~60amps 20cfm

 

looks great dude

between that top weld and the lower weld in your second picture what did you do to improve the color of the weld?

 

the color was the same.. i used a scotchbright pad on the bottom and it made it silver so you could bearly see there was a weld there.

 

Looks heavily undercut in some areas. Also, don't see much of a bead profile. In all honesty though, the pic is just too far away to really say much about it. The metal has a strange surface to it, so it adds to the difficulty. What does your penetration look like from the inside?

It looks like it's just a fuse weld. But looks like a good start

 

I was going to say the same thing. Very undercut in some areas. Either you are using no filler material or you are using a very thin gauge and not enough. Looks good for just getting started.

 

this was done with very little filler.. i'll post some new welds up later.. I think the pictures make it look more undercut than it is on the right side though.. the center is even or a little above.
