    First welds.

    I didn't want to intrude on the other post, but I've always wanted to learn welding so I picked up a Hobart 140 last week. Made a little D.I.Y. parking stand for my rear blade as my second welding project. First project was welding an old hitch on the rear of my box blade so I could move my trailer around.

    Welds were ugly but it held until I accidentally dropped the blade off the forks directly onto the hitch and it broke off. So this morning I ground everything off and tried it again.

    First pic is the parking stand and second is round two with the hitch. I think I need to extend it up and down from the gap more, but at least it looks better, to me anyway. To my untrained eye, it appears to have gotten a little penetration. I know we have some accomplished welders here, so any tips on things to try from here to improve?

    I'm not a professional welder but to my untrained eye the second weld looks good from a process/movement/puddle standpoint but seems to have very minimal penetration. Were you running the Hobart 140 at it's highest setting (i.e. thickest metal on the chart)?

    I assume you are using flux core, if so what diameter?

    I learned to weld at adult ed classes in the 70's. My stick welder is so old that it was from Montgomery Wards. take your time and practice, practice, practice. I often thought about a new mig welder but always found something else for the money. My rule "has long has it holds spray paint will hide it".

    Good for you leaning something new! Thanks for sharing your first experience.

    I seem to be in a mode of life right now where I crave learning stuff like this that I never did before. Welding has been on my list forever but having a wood plank floor in my barn and shop it has made me hesitate. Yeah, I could do it outside but....

    I guess that practice makes perfect with most things like this. And what a great resource we all have here with so many folks willing and happy to help and spread their knowledge to us all.

    Yes it is flux core, .030 wire. I had it set for the thickness of the box blade metal, which isn't as thick as the hitch metal. I think it was on 50 and 4. Better to set it for the thicker piece? I want sure on that one.

    Thank you. I'm stuck outside as I have a wooden floor too. Not the most convenient, but it'll work.

    I've been hobby hunting for years. Hopefully I've found something that is fun and useful, and not too expensive.

    I agree with all of this, try turning it up to achieve better penetration.

    I'm self taught too, on a Hobart 140ez MIG as well. I bought a couple welding books, read them, watched hundreds of Youtube videos and 'went to town'. I won't pretend to tell you whether you did good or not, as I'm not a qualified judge of that.
    I'm guessing your receiver is on top, by seeing the hole there? One thing you can do is add a triangle gusset (1/8" or 3/16") underneath it, at the front and back, to give the receiver more support. Round out the corner at the 90* angle, so it fits over any previous weld bead. Then you aren't completely relying on just the welds where it rests on top of the BB.

    A tip for welding thicker steel to thinner steel, is to preheat the thicker steel with a torch. Doesn't need to be glowing red hot, but get it hot. Then focus your torch more on the thicker steel, and "walk/lead" your puddle into the thinner steel, so you don't burn through it.

    Under cutting the edge of the weld bead is my biggest hang up. Plus I don't weld enough to get really good at it. I do it just enough to be dangerous.
