It's not pretty, but I've seen (and done) way worse. The shiny middle weld is the best bead of the three I layed today. I had to fix an arc welder at school today and I needed to test it. 75 amps on 1/4" steel plate.

I tried to weld once. It was just a blob. goddamn welding rod kept getting stuck and i couldn't see anything in that mask.
I should've tried harder. DAMN YOU SKILL THAT I DONT HAVE!

Dude, get an automatic mask. They're great. My rod got stuck to the steel the first couple tries today (I also did the top two welds), but I got back into the swing of things again.

Turn it over and post pic of bottom side.
I weld some, but BrownDogWelding would be the ultimate decision maker on these matters.

The bottom has welds done by other people on it. I just grabbed a used piece of "practice steel" (2"x3" cuts of metal that we use to practice welding). What should the underside look like if I did a good weld?

All I see is penises and a line. Is there something wrong with me?

Generally it should show, but not distort the, metal on the bottom.

Very wrong.

Either that, or try mig welding. I found it to be much easier than stick.

Bottom wouldn't show much in this pic. You can tell more from the bead profile.

Not bad! I'd pry slow down a little bit, just give the rod a little wiggle, and make sure you're laying it in at about a 45* angle. What size was the electrode? 7018? I'd pry have the amps up a little too. Rule of thumb is 1 for .1....so if it was 1/8"(.125) rod start at about 125 amps, then adjust from there based on your machine, the position of the weld, and your style.

Thanks for the tips! Going too fast has always been a problem of mine. I've never known how to choose the correct amperage, I always have figured 90 was a good starting point but it looks like I'm too low. I've determined I shall start practicing again since I have access to a welder. I was using a 6013 electrode.

You would know much more than I. I always look at the bottom side of my welds to see if I got too hot. But I generally weld on thin stuff, so...Is that in indicator?

No worries man. 6013 is also mainly a sheet metal rod, 1/4 is a little thick for it. Shouldn't matter just running beads though. Just FYI.

It can be, but it's one of those things that's gonna be different for every material and thickness.

Thanks for your input. I do appreciate it. You are a valuable contributor on this site, sir.

Like BD says, slow down your travel speed and turn up the amps. The 1 amp per 0.001" diameter is a good rule and will give you a good starting point.
Also play around with how far you hold the electrode tip from the base metal. The hold off will have an effect on the bead shape and penetration. Not sure if you have access to any of the AWS handbooks, but those have very good information. Or dig around on aws.org, you might be able to get a lot of stuff there.
