    I don't know if anybody mentioned a good welding cap especially if welding at or above your head. Keeps the blisters off your head.

    Truer words have been spoken not. I don’t know how to weld but I design nuclear power reactors! Nuclear grade welders are the shiznit...and get paid well for their skills.

    I'm an electrician down in the springs. If you decide you want 220 in the garage let me know. All it'll cost is material, maybe some beers and to let me drool near your truck.

    Just fucken jump in and start doing. Trial and error.

    I became a plant manager over a company that largely did welding a few years ago. They gave me shit because I didn’t know how to weld, so I jumped in and started welding. I really added to the p&l’s scrap factor that first month, but I can weld the shit out of stuff now... and it’s damn pretty.

    Go burn some stuff man.

    Pics of the welding cart I made...copied off of Pinterest. Bottom pic shows my flux welder on the bottom, with the plasma cutter in the middle. Lotos D50 ($350 at HD).

    Some recently cut up 1/4" plate steel I did for a friend with the plasma cutter. I'm using some of it now to fab mounting brackets for the sliders I've made.

    Thanks. In the last pic of the cart you can see the 1/4” round bar I added as rails on each shelf. Keeps everything from sliding off the side. The grinder holder is just some 3/16” x 1” flat stock, entire length of the cart. Just slip the grinder over. Saw it also on Pinterest. For a hone garage welding cart, waaaaay better than the HF one for $35. That one was just too light weight for me

    All hail the harbor freight grinder! I have 3x of them too, one for grinding/cutting, one for flappy disc, and one for wire brush. For $10/ea you can't go wrong, and I have yet for one to outright break that wasn't a result of me hucking it across the shop to release anger hahaha

    Yeah, the HF welders come with an extra piece in the box. It's the part that wears on the brushes. Forgot what it's called. Save it, because when the grinder stops working, just replace it with the extra one. And you're back in business. Unfortunately, I do not know where to buy extras of these, but not worth it. Once you've replaced that brush/wear thing once, you should have a year on that grinder. For $10, go buy another. In fact, when all this virus crap ends, going to buy another...then put it in my car, download another 20 percent coupon, walk back in and buy another. I usually keep four on the cart, and one new one in the box in a cabinet...just in case.

    Get a decent grinder and it will last for a long time, with way less vibration, and not self destruct half way through a project.
    A 4 1/2” makita with a paddle trigger is economical and durable. They often sell them 2 in a box.
    A $10 grinder is about as good as a $10 hammer, the only bonus is you can use the $10 grinder as a hammer.

    Oh my...:eek2: all this talk of gorilla welds, undercut, porosity, slag inclusion ,which by the way is a welding term. Hat's off to whoever said that.

    If you are constantly grinding your welds, then you are a grinder not a weldor.
    Most important thing to do prior to any welding, whether it's for practice or production is clean your metal good of mil scale, rust, paint, etc. Dirty metal is the main cause of porosity, especially in the smaw process, lack of gas in gmaw/gtaw.

    Someone mentioned stick welding is the easiest process, well to some it may be, but truthfully mig is essentially point&shoot, set up is the main thing, once dialed in you can develop your own technique rather quickly. Stick takes time and effort.

    GTAW is where it's at. While it's not the most practical process for the wknd warriors, it is the cleanest, best weld producing process. It's also the most expensive, especially if your looking at aluminum and water cooling features.

    I wish I had the money to open up a small school to teach guy's like yall that want to learn to weld. It's music to my ears. I taught welding @ my local college for 5 years, and miss it terribly. It was the most gratifying job I ever had.

    I will leave you with a few tips for stick- 3 main techniques 1- Arc Gap, keep that rod as close to the puddle as possible 2- Rod angle, depending on position 5/10%, slightly. the more straight up and down, flatter the weld. 3- Travel Speed, slower you go the more weld deposit, faster you go , less weld, and they will look like hammered dog shit.

    I will suggest for anyone looking to purchase a welder, go ahead and spend some extra money. Get a set-up with at least a 60% duty cycle. If your not doing a lot then you could go with a cheaper unit. Typically any welder your plugging in to 110v is a waste of time, just my .02. Good luck out there!!!!!

    Quite true. At my last company we had a bunch of eye injuries. Investigation found that most of them were from grinding particles in the eye, mostly welders. My response was "get better welders". But that's easier said than done in this area.

    Yes it is. Welding is a Art of your technique. You either have it or you don't. No in-between

    Agree.

    One thing with GTAW, probably not applicable to the home welder, is it's not for large welds. It took me quite a while to get our shop welders to stop TIG welding everything and go to flux core. It mostly happened because we replaced them with other welders from a more production oriented environment. We built a lot of medium to large foundations and 3/8 or 1/2 fillets and 1/2 plus butt welds aren't uncommon. The guys that only wanted to TIG weld took forever and distortion control was next to impossible.

    For me, I never got into GTAW. I'm extremely right handed and my left hand is mostly retarded.

    lol, yeah in the field it's all about production, tig is more on the pipe side of things. It's a great process to learn, and will make you the most money out in the field. I wish I learned it a lot earlier in my career. I would definitely be in the aerospace side of things :D

    I got hot with one guy and said you just want to wear a white shirt to work like some kind of f'ing executive. Apparently he was offended, he went to HR. That's how I got treated when I first started in 1980, didn't bother me:notsure:

    Didn't you tell me you welded Omega seals?
