I was thinking of making a welder that uses a capacitor bank, and does stick welding (STAW). How would I go about doing this? Any other ideas for homemade welders? A small desktop welder?

Hello, I am currently in the process of making a pneumatic air-gun, I have previously made one out of PVC but had major leakage problems.. Ive moved on to metal.. Will high pressures break the welds and fly off and hit me in the face?? What pressures? Can I weld brass to steel?

So I see tons of instructables for no weld bikes, trailers, and all kinds of stuff. Well, I just got a new flux wirefeed welder. I need something to weld! It has just been sitting there after I stopped practicing to save some wire. I welded the seats down in my car and want a new project that's not too hard. Give me your ideas!

This is s a general forum for people to post questions and tips they have found over the time they've spent welding My question/tip is this - I recently had to weld two pieces of oddly shaped steel together. Placement and alignment was important for me but the shapes of the steel pieces made clamping them together a bit of a mission. My solution was to position and hold the pieces of steel using prestik (probably the south african equivalent of U.S. bluetack - maybe chewing gum could work) and then the steel pieces didn't move while I tacked them in place. My question is obviously whether this is a questionable practice because of fumes (I didn't notice any) or weakening of the weld from the prestik inclusion (it seems to be holding quite nicely though and the piece is now the switch activator for a press strip feeder. If you can't think of any problems then its a tip

Howdy folks, I've got a question that I hope someone might be able to help me with. I'm interesting in creating a way to "weld" fabric together. Basically taking two pieces of fabric, using heat, pressure and "glue" attach them together. Think of Nike footwear and there sewless uppers. Anyone out there done anything like this DIY style? I've got a number of projects that I could create from it. Thanks in advance, TOM

My father-in-law just gave me this 295 amp arc welding rig (he's forbidden to use it anymore--pacemaker.) It's complete with mask, rods, etc. I've never welded before, and have a couple questions:-- Any good books or tutorials to recommend?-- I live in an older home (1930s), which has bus fuses and certainly can't supply 295 amps without burning out (or down.)Should I get a separate service installed for the garage? Is it expensive? I've looked on the power company website, and it's typical superficial information for the average customer...

Hello I am an exhibits designer and builder for a museum. I weld and do some machining every week. I would like to take formal classes here in Philadelphia or the surrounding area but I can not find a single program! One would think that in a major city there would be something but no luck so far.

I'm building a cnc machine and I just bought a whole bunch of steel vat a surplus store. I need to braze or weld them together, but I can't braze since the objects too big for my propane tank, it disipates tthe heat to fast. I can't afford an arc welder. What should I do? I don't want to use nuts and bolts because that adds wiggle to the machine and I lose all of my accuracy.

JB weld, the gooey-at-first,tough-as-rock-later-on stuff we use to fix all kinds of stuff, from broken chairs to unsightly holes- the number of possibilities are endless. So, is it possible for large amounts of Jb weld to be casted into a bulletproof suit that can actually save lives?
Asked by Boppo3 8 years ago | last reply 8 years ago
I tend to do a good bit of research when I purchase anything. I will spend hours finding the deal that will save me five cents. While this doesn't make much financial sense for me, maybe it will end up being worth it if you can save a few cents in the process!The only step to this instructable is a list of the best places I've found to purchase JB Weld. For those who are not familiar with JB Weld, it is, simply put, God, in a tube. It is an epoxy that when mixed (and mix quickly, you only have about 20 minutes of pliability) will set within 4-6 hours, and cure within 24. Once cured, it has the strength of steel, can bind with glass, and neatest of all, is actually conductive enough to use as solder!Note that I'm only referring to the original JB Weld, model 8265 (and 8265-S). I find the stick version doesn't adhere as well, and the "Kwick" version isn't as strong. I also tend to be stubborn and just stick with what I'm comfortable with.Since the invention of Duct Tape (genuflect) nothing has been so valuable to mankind. Thus, it's not surprising to find it anywhere from $9.99 a tube, up to $14.99 per tube. So how much should you be paying for your J.B. Weld?If ordered online, you can get it for as little as $2.95 per tube!Note: These prices are only accurate as of the posting of this instructable (29 June 2009)Okay, so if you've come this far, $2.95 per tube sounds pretty exciting. Keep in mind though that you're also going to end up dealing with shipping, so we'll see what the end result will be. When in doubt, if you have a local Ace Hardware, Lowes, Home Depot, etc. look there first. You avoid shipping, and the Ace online outlet sells it for as little as $3.25 per tube (No idea why nobody else, including Sears, KMart, Target, etc. carries it online). If you can find it in the store for that price, that would be your best bet. But assuming you don't have a local Ace Hardware, or since they're locally owned the Franchise Owner is a prick that overprices things, let's see how the following websites work out.First, it's important to note that while you will find many other places online that claim to sell the JB Weld for as little as $2.95 per tube, just try to purchase them. I'll wait... Back? So as you saw, 99.9% of these sites use the Amazon.com checkout system, and only allow ONE TUBE AT A TIME to be purchased. They then hit you with a $4.99 shipping fee for each pop, and now you're back to paying $8 per tube.On to the real suppliers:#1) Tool Explosion - The best price I've found with free shipping, but their free shipping minimum purchase is $100, and their JB Weld was only $3.76 per tube when last checked! One of the better deals out there. Between $100-$130 worth, this was the best deal I could find.#2) Alexandria General Supply - To get the $2.95 price here, you have to buy in 6 packs, otherwise it's more expensive. But hey, more JB Weld can only be a good thing. They seem to have a starting-rate of $17.05 for shipping, which is nearly as much as the 6-pack of JB Weld, making them almost $6 per. However, the more you order, the price of shipping will actually start to go DOWN. At 7 cases (42 tubes), it dropped to $7.41 for shipping making it $3.12 per tube, and at 20 cases, it was only up to $8.16 for shipping, making bulk purchases very much worth it. At $131.31 for 42 tubes, this was the best deal out there, and only gets better the higher you go. They do not accept PayPal, but do accept all major credit cards.#3) Ace Hardware Outlet - Don't ask me why AceHardware.com doesn't carry it, but AceHardwareOutlet does, but I'm not going to argue. At its respectable price of $3.39 per tube, it's not a bad deal if you're buying in bulk. Unfortunately, for just a single tube to ship, you're looking at $6.39 for shipping. The shipping rates only slowly go up the more you pile on, so if you're doing some shopping for some other hardware, Ace is The Place... For Me... (Plus, they take PayPal!) For individual tubes assuming you can't find anything locally, this is the best price going. At least buy 2 or 3 tubes at a time to make the shipping worth it, though.#4) Hands-On Tools - Another site with fair shipping, and a decent price of $3.66 per tube. Not much to say about this one, except that they seem to be one of the more reputable sites selling the weld for a good price. They work with the BBB and have a good rating, accept PayPal, and give you percentage discounts the more you buy. All around a solid company.#5) Castle Wholesalers - One of my personal favorites (since they are located near me, mostly) selling the JB Weld at $3.47 per tube. However, do keep in mind that you have a $25 minimum order here. Their prices are pretty standard for shipping, so you can add about $1 per tube once you've bought the requisite $25 worth. The more you buy, the cheaper the shipping gets per tube, as well. Only Visa and Mastercard accepted.#6) College Toolbox - While their price isn't the best, it's still a fun site with some decent stuff at fair prices. At $4.11 per tube, it's not necessarily worth the purchase here unless you find enough of their gear to get the "$150 purchase gets free shipping" thing. (And they take PayPal)In closing, if needing just a tube or two, your best bet is always going to be to shop locally, and buy from a hardware store. But once you start getting into the $5 and $6 price range, there are some decent places online to pick it up (if you don't mind the wait). Always take shipping into account, and always avoid Amazon.com and their Affiliate's rip-off schemes. If you see the Amazon logo, run far and fast (or at least close the window). E-Bay is equally a rip-off, only moreso as you're starting at the $9.99 level, and then tacking shipping onto that.For the hobbyist that understands the glory that is JB Weld, drop the $130 and get enough JB Weld to last you for a long, long time. For all others, I would recommend avoiding purchasing it online unless you absolutely can't find it for a fair price in your local stores (I can't stress that enough. Shipping is the debbil.)Hope this helps someone, and if anyone finds a better price, feel free to include it in the comments and I'll add it to the list!

I mean it has bad cords and I don't even know if it is worth it. Is it possible to get shocked even though it is not plugged in if I open it up to look inside? I could get new cords and stuff if the internals are working. I was going to hook it up to a power strip ( the one with a switch) so I could see if it works. But Im nervous, is it worth it? If not i was just going to use the case for something, a refrigerator on the inside with all the inside stuff taken out of the welder itself.

Having seen the microwave transformer welding kit and similar projects I started wondering about this one... Induction cookers are basically one side of a transformer and usually just dissipate current in to the pot to heat up the pot. But they've a high number of coils and I've seen them rated at 3000 watts, so if you made a coil that was a few turns of thick wire to be the other side of the transformer you'd possibly be able to have a huge current low voltage supply similar to the microwave oven welder. I imagine there'd be safety devices that may need disabled but the idea of your oven being a welder seems cool to me, especially if someone had a need to weld often and their kitchen was through to their garage.
