I can't weld wearing glasses anymore at all.
I was only formally trained with gas welding. That's the best to learn with because it comes at you the slowest. You form the pool as gently as you want and then feed in the filler at your own pace, as needed. It's not as bright, either. I went to stick then and it sticks. That's the hardest part to learn--to strike the arc. But then, again, you control the pool and feed in the filler as needed. With the wire-feed, it's all about setting up the machine. It's the easiest IF you get the machine set up properly. It's easy to make a nice bead that sits up on top the the work and doesn't penetrate, which is what your weld looks like. Especially a 120v machine. If that's what you have, bevel a V in there and then fill the bevel. Bring your own penetration. BYOP. Starting with a gas or stick welder gives you a quicker leaning of what penetration is.
I have a nice Lincoln MIG but I still mostly use the Hobart 220V stick welder. I like clamping in sticks. Plus, you don't need to clean anything. As long as you can complete the circuit, you can weld it--just don't wear nylon clothing. Get stuff that says cotton. 3/8" plate in one pass or an exhaust pipe using 1/16" rod. I even did cast iron before, using cast iron rod and heating the piece in the oven before and after and letting it cool in there. My bandsaw had fallen over and broken a cast bracket. It worked perfectly. I've also cut metal with the stick welder using the rod for that purpose. Not as clean as a plasma cutter, mind.
