Resistance soldering looks so cool

[MrPlacid]

Saw this on youtube and it's so cool. I've never heard of resistance soldering before, it does seem similar what I did once with carbon rod from a D-cell battery and a DC power source. *sparks* Found out about this company while search ebay for foot switch. Man, I love commercial equipments, I am practically drooling at the mouth watching these videos. Too bad everything is hella expensive even on ebay.

You do a lot of plumbing do you?

Not certain how this is any benefit over oxy-acetylene brazing.  I guess you don't need to take the gas tanks with you.

No, I don't do plumbing. Anyways, that's probably a bad video to link since everyone would think it's meant only for brazing. I should have linked to something like the tweezer or soldering stick video like this.



I think one advantage to using this over the blow torch is that you're only using electricity. And everyone has electricity I can see how this is useful in some assembly factories where those gas tanks are eliminated. Plus the unit operate on 120V AC which meant that factories owner could use any household outlets instead of the commercial 240V.
 
This seemed to be popular with people building train models since when I googled those sites pop up alot.

Also, it seemed to work similar to those cold heat soldering irons. Those irons are a piece of crap.

I am into this kind of things because I've always been fascinated with commercial equipments. They are usually very well made. However, this stuffs seemed easy to make. One day, I gotta make a homemade version of their tweezer.

I used to use resistance tweezers when I was in the RAAF for soldering high density mil-spec connectors.
I never saw them in use at any of the civilian electronics labs I subsequently worked in.

I think one of these would be much more fun!

Sorry what is RAAf ?

What is RAAF?

Holy cow, look at that huge capacitor! I'll stay far away from that till the need ever arises.

Now that's what I call a soldering iron 

It seems to me this is almost real close to a TIG machine.
If you the output stage was a H bridge you could get alternating polarity at the probes.
Bit of argon shielding gas and alloy here we come.....

I like the metal cutting ability myself.
There's another guy that made a similar spot welder but has now modified it to a pulse arc welder.
I just KNOW I can find a use for this - somewhere.

 I have done a lot of torch braising of flanges, etc. on larger RF feedline, and often wished that I had one of these machines so I could do it faster... 3" and 4" copper tubing sinks heat really fast! Maybe i should just get around to building one for myself, just never had time.
