How much overlap between the wires, and do you put R or NR on positive post?
minimal overlap, about 2mm. R wire on positive post. Wires need to line up and be parallel as much as possible to increase joining surface area. I have even more consistent joins now that I got a magnifyer lamp and can see what I'm doing
Funny, I can only get successful welds with the zapper if I leave a large overlap, like 5mm+.

Just started reading about these methods, and I'm wondering if there are such devices that don't require a workshop - those I see are somewhat bulky and not apartment-friendly.
Maybe we can persuade imeo to produce a small polished Flux welder, the GG-Flux?
yeah I use Tsaf in position 4 for 32 gauge kanthal and 30 gauge nickel.. probably about 4mm of wire sticking out from the clips.. ~1mm overlap
tsaf in position 3 is working so well
Good call I use position 3 with 32awg to 30awg end to end. I did overlap when I first got it and had too many breaks. Now it is just the charge time being correct and end to end. A good snapping pull and it hardly ever breaks. It did take a lot of trial and many errors.
It's a very simple circuit to design and build. Add an LM2577 board and you can add voltage regulation by way if a potentiometer as opposed to pressing a momentary switch for a determined amount of seconds. I designed and built one today as a proof of concept with 15.00 worth of parts. You would, however have to have some electronics knowledge, a soldering iron and a few other essential tools. Now that it is built and working on a breadboard I'll figure out what case I want to use and how "fancy" I want to make it. It will be a while because I can only work for small periods of time sitting up. (Bad back). Once I get my design finalized, I'll PM you a parts list if you think you can built one. If not, I may be able to build one for you depending on how my health issues are.
Keep in touch with me.

I am looking for a wire welder to make perfect non resistance/resistance wire connections any ideas? On another note how does onedelete there own threads (Some are made in haste and need to be deleted)
Very true, you can get step up boards from ebay with LM2596 etc etc and simply use a switch. There are also variable voltage versions you can use.
And better keep it below 35V on the capacitor.
A 1000μF 50V electrolytic is suitable for this but you can try others too.
There is a how-to here as well.
I have no idea if it's good or not, I don't really know much about building these things, but figured I would post it!

It could be better but it will work. You can try it yourself.
Keep in mind if you have a charged capacitor you might get zapped.
These circuits do not have a discharge resistor on the cap (no design experience or whatever) and no switch to isolate the LM circuit.
But it will work.
A parts list with picture slides of your construction steps would be nice!
Ok, so I got a hold of a Tsfa+. I have only been able to play with it for just a bit. But I am not having the best success with it. Was I overestimating the capabilities of this thing? Anyone with experience, please let me know. Thanks.
