Been praticing a lot lately with my Lincoln 3400 weld pak MIG here are some of my half a$$ welds. Let me down how I can improve please. All comments are welcome I can take the bad news.





I was on the C setting on the machine and wire was feeding speed was at 4 and I was using 75% Argon and 25% CO2. .30 mild steel wire.

 

I'm jsut learning also. It would probably be a good idea to say what technique your using, so the pros can give you more pointers. I hope i can get some gas soon, im starting to get flux core welds to come out decent.

 

you are using two hands to hold the gun when you weld right?

 

On the second pic bottom bead I wasn't I started to use both handes afterwards. I had spot welded the pieces together first then connected the spots. I did a one full non-stop pass at the end of the day it looks better than rest (at least I think it looks better)I dont have a pic up I'll post it later.

 

The bottom bead on the pic is one I did in one single pass and of course you know that cause the bead is so uneven.
