Your heat looks good. Looks like you are advancing too much. 7018 is a fast fill rod. Strike off, let the puddle fill, and then just slowly move rod in direction you wish. Make sure to keep rod in the puddle. You will be moving very slow, a 3/32" stick will move me about 3"-4" of weld. The longer you stay in the puddle before moving, the wider and higher the weld bead. The faster creates a skinnier lower weld bead. Remember that welding is a slow process.

I know what I just wrote does not sound like it makes alot of sense, it confuses me also to try and type it. It is easier for me to jump in the booth with someone than type it. Hope you are able to make sense of it.

Slow and steady makes a great weld. And lots of practice.

Here is what I had to build the other day. It has some mig welds and stick welds:





Some close ups of the mig stuff:

This is the side of the fish mouth:



This is the tight side of the fish mouth and a rolled mig joint:



This is a thread o' let welded with 6010 (5P+):



And this is my baby at work:



This baby is one stop shopping. I run .035 on the left and .045 on the right. I can run MIG, RMD, Pulse or Flux. Plus it has stick and Tig. It is all about putting out the inches of weld at work. The boss is only happy when your hood is down.

Your heat looks good. But your speed varies alot in the first weld to the left. If you look at the first weld you moved too slow at the bottom and top. You can see the two spots that are discolored compared to the other portion of your weld. The middle weld looks nice. Your speed and heat looks good.

Do you have any photos of the front sides of the weld? You can tell there also if you have any undercut.

What weld process were you using?

Your heat does not look bad. Make sure to clean up the weld and inspect the edges. Make sure you do not have any undercut. If you do, you have two options. Turn your heat down about 5 amps, then five more if you still see it. Second would be to wash your edges a bit, make a small "Z" motion with your stick while progressing forward.

My first weld ever with my hobart 140. Im running it flux cored until I get my tank filled. Take it easy on me now, it was my first attempt haha. I simply laid a bead on a bedpost that I ground the paint off of. Bead on the left was a test to see if i was grounded due to the paint. Bead on the right is my first real attempt. Any suggestions?

take a brush to it after you weld it so we can see it better next time. I am no teacher so i wont comment on the weld, but it is hard to see.
