Another awesome build Break

 

This is cool.

 

Dave's da man!

 

Am I the only one that has NO idea what I just watched?

Not sure if its from the same maker but this is the first vid I saw of it, might explain more
The Tsaf - Res & No Res wire joiner - YouTube

 

This is from our new resident modder - Diver.

 

For attys like the Odysseus and Penelope you have to join your resistance wire to no resistance wire (usually silver or Nickel) as you have a fairly long run of wire before you get to the coil. This is usually done by wrapping the two wires together and can be a bit hit or miss. The device generates a short burst of high voltage/current discharge for a tiny amount of time so when the res and no res wires are touched together they become arc welded and joined. At least that's what I think I saw

 

This is not for RBAs and Genisis atties that use Kanthol or Nichrome wire which are both resistance wires.

It is only for use with items like the Odysseus, Penelope and the recently release Odysseus clone aka Terminator or Nautilus.

 

Do not forget the Killer 705 atty as well

 

Well, I just finished my version of the wire welder, works awesome and cost me less than $5

 

Ok now I'm jealous. Honestly glad you were able to get er done!!!

 

Perhaps I'm missing something, but why can't ya just use a soldering iron?

 

I need a few more parts and I will be going for this as well, done shocked the peediddle out of myself a few times playing around with the flash board.


Because the temperature that each metal metals at a different temperature. Once you get one hot enough to that the solder will stick you have long past the operating temperature of the other and ti is melting.

 

All I gotta say is how much and,ware can I get one?

 

Yeah....

Kanthal melts at approx. 2500F and silver at 1571F, but if the wires are twisted and the silver melts into the connection, it'd still work electrically wouldn't it? You are just keeping them stuck together since already physically twisted together.

It's a classic technique: http://www.d-series.org/forums/diy-forum/101973-diy-how-cleanly-solder-wires-together.html

Perhaps a somewhat cold solder joint, but we ain't doing IC's here. I have 33awg Kanthal wire and 30awg .999 soft silver NR wire...I'll have to test... ;-)

 

every time I tried the silver just got soft and let loose but maybe (and there is a good chance of this) you have better soldering skills and equipment than I do.

 

Also I would recommend trying the angel hair thin solder as the thin wires heat up rather quickly an using solder that is 5X as thick will be a fail before you get it hot enough to melt. 999 silver seems to melt way quicker than 1571 and can even be melted with a bic lighter.

 

I went to the thrift store and picked up a 30 volt power supply for a HP printer. It puts out 38 volts unloaded and works perfect with a 1000uf cap.
