On behalf of Expert Village, I'm Terry, and I'm here to tell you today about building a wrought iron fence. Here I'm going to show you two types of welding, downhill, and uphill. Uphill is usually done for strength. Downhill is not as strong, but it's faster, and if you're working on thinner material, then you don't burn in quite as long, and you can lay a bead much quicker. Going uphill you have to move it a lot faster. Right now I'm going to show you downhill though. Making in a circular motion while you're going down. No need to preheat because the bead wants to go ahead of you anyway. Okay, I kept my nozzle pointed up because I'm trying to push that up to keep it from going down. If I was to go down, it would obviously lay in a lot less material. You wouldn't have near as much material laying in there. So your nozzle wants to go up at a forty-five degree. I'm ambidextrous so I can weld with either hand, upside down. Some people, this just feels really weird. They think they have to get in here and go like this. Well obviously things are in my way so you have to be adaptable to where you can weld in any position. That's a downhill weld. Now I'm going to go with uphill weld. On an uphill weld you also want to do the horseshoe effect, or you can do the zero effect. Now, the weld's not going to look like this. It's going to be high in the center because you're going to be passing over the same place twice and it just, it lays in more material. But you have to move faster. If you point your nozzle upward, like I did the first time, see how fast I'm moving the nozzle, I'm having to really stay going. It's not too bad of a weld. Let me touch on cleaning real quick. Keeping your nozzle clean, and free of what we call dill berries or dingle berries, won't ground out your nozzle, won't ground out your cone to your wire tip. See, much better looking weld. Now what would happen if I was pointing down and trying to follow it up? It would ground out way too much, it would look like a bit old bugger on there. See how it's mounted up in the middle? It's virtually flat. That's what the mig weld would do. Stick welding is a little more, is a little more complicated, of course because you have to work your rod back and forth. With a mig welder that's all you need for building a basic project.
