Want to build your own 70Amp Welder? This is not for the novice but great for ther hardcore survivalist and radically self reliant welder to know.

Much to my wife's chagrin, I spent the entire day reading all these welding links and watching the NCAA tournament. Nevada sucks. haha -

Thanks for the assist. I am ready to go forward and Weld.

Ask him about sheet metal. I'm still going through the links he PMed me.

Great sites as well. I'm sure he can fill you with knowledge of other manufacturing techniques as well if you dare to ask. The only problem is finding the time to finish reading them.

The Brazing Book link has been very helpful. The only problem is my g/f was looking over my shoulder as I read through it and she has some projects of her own that she wants to try....which means i'll have to share equipment. This could be quite fun. Thanks Toolmaker.

There's many worse things than having to share your equipment with your girlfriend!

I'm glad everyone found the learning resources helpful. I have about 500 or so more that I will refrain from posting since alot of them are heavy into commerce ads. I tried to post the best sources I have that are commerce free. As Mike mentioned I also have alot of resources for fabrication and other manufacturing methods.. I am after all a Toolmaker and have to keep up with this stuff. A few of those links have other wonderful things covered, just take out the end of the link and go right to the .com and see what else you have. The MIT website is a really nice one I found recently that covers a nice wide range of subjects. I hope other universities follow their example and provide some free courses. I have worked with Friction welding and can assure you that it is not as easy as some of those links make it out to be. Using a belt driven mill is not the way to go. A gear driven head will give you what you need but again it is not for the faint of heart. I'm a bit of a lunatic when it comes to milling so it was nice for me to try it out. I still prefer MIG and Stick when I need to weld and will probably try to get into welding more myself at some point.

....dammit! Now I want to go out and weld something! Damn you ToolMaker! Damn You!

Ditto. I can't even START reading those links right now, until I've finished what I'm working on...But I DID pull the oxyace rig out for the Spring!

Darn, now that you started this thread, it does occur to me that learning to weld could be quite useful!

Now, when am I going to find the time, money, and other resources....?

Removing rust from salvaged materials can be done with Electrolytic rust removal. The following links will have instructions and illustrations. This process is really quite easy and safe as long as directions are followed precisely.

As always some of these websites have more information on related subjects.

so here's a quick question - i got tired of the splatter and having pore problems in my flux-core mig so i started using normal wire without gas. anyone else ever tried this? solved splatter but only helped a little bit with micro holes, and its still a bitch to weld thin stainless without burnthroughs.

Use gas 90 percent helium, 8 percent argon and 2 percent CO2. NEVER try to weld thin stainless with flux core. Flus core uses more heat because of globular transfer. Unlike short arc, where the weld puddle cools every time the wire touches the base metal, the arc remains "on" constantly with globular transfer. You also want to try to use the "thinnest" wire possible and feed by hand. Also keep try to keep the heat down to avoid the HAZ/burnthroughs. For long welds like around a thin cylinder try welding an inch than skipping 4 or 5, sometimes called skip welding. Not sure if you tried this but heres another tip.. keep to the middle of the puddle instead of the edge like you normally do, this will allow the puddle to protect your base metal. One final tip would be to increase cooling of your work with a piece of metal to act as a heatsink. Basically any piece of copper or aluminum near your HAZ should do the trick. If this is not possible than you can try to weld in a colder room. And on a final note try feeding the wire by hand.

thanks for the followup. problem is i tried most of that except using gas because its a flux-core welder, no gas support. but knowing flux core is a slightly hotter weld is helpful.

but i have to wonder about holding it longer in place, when i do that the wire makes a serious pit with a large nipple on the inside. in other words, it pushes the wire to the bottom and cools like that with a weak side of the pit or hole.

There is only so much one can get away with. Two of the most important factors with thin stainless is 1) No Flux core and 2) tri-mix gas. ESAB has some information somewhere on one of the "course" webpages. I might have missed something since I'm more of a metal cutter rather than joiner. Also is your worst spot where you start your bead? Sometimes the smallest shit can fuck with ya.. like trying to snip the end of your wire instead of grinding a point.

No, i don't mean that figuratively, either.
Welding = sexy.

Thermite in action is a totally awesume use of flames.

Stand Back !

Not very controllable, though, best for railroad rails and
very heavy metal projects only.
