welding

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?

 I am new to welding and have many questions. Is the gas held in a separate container or held in the welder itself?

Spot welding 1.5V battery tabs Answered

Fabric welding, no sew, hf/rf welding

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

Arc Welding Advice?

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...

cheapest welder for aluminum?

I need to weld 3/16" sheet aluminum for a boat i'm making and want to do it at the cheapest cost. this welder (http://www.harborfreight.com/90-amp-flux-wire-welder-68887.html) says it won't do aluminum (and i'm not sure 90 amps would be enough anyway). Is that true? What if i bought the 180 amp model? Any suggestions for other welders?

Joining two small pieces of metal with a metal cylinder tube

Hi, this is my first post, I hope that someone will be able to help me :) I am trying to join two motors normally found in alarm clocks, I wish to join them with a metal cylinder with about a cm bigger diameter than antenna's found on radios. How would I go about joining each motor to each end, I cannot get welding and don't know if it would apply even to such small electronics, soldering seems impossible as it won't join, any advice is much appreciated, thanks P.S The end product would look like the base of a RC car, but without the wheels thanks.

My Grandpa has a Lincoln 225 Stick Welder but it is really beat up. Is it worth trying to fix? Answered

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.

how to bypass the safety on a battery charger?

Ive been working on a cd welder for battery tab.. very simple car audio capacitor with a battery charger. today i rebuilt the whole thing with new leads wiring and new battery charger that will shut off when it hits a full charge. now it wont charge at all because it apparently wont charge anything thats not a car battery with proper voltage already existing. since the capacitor dumps the charge and leaves nothing, the charger just thinks there is nothing there. can anyone give me a crash course in float chargers and how they work so i can single out what i need and bypass everything else

How can I connect a thin sheet of metal inside a circular metal container?

Without welding because the container and metal sheet are kind of too small to weld. I'm thinking of soldering them (I'm desperate) but I'm not sure if it will be effective. There will also a process where I will put the container in a boiling water bath so it is not possible to use adhesives that will melt. I know this sounds weird, but it's a school project. Thanks!
