coils with welded ends

[aliceisinwonderland]

good evening! I was wondering why some pre-made coils have a larger(thicker) wire welded to each end? do I have to do this if I make my own single coils? thanks folks!

im not sure ive seen what your referring to, but if i had to guess id say leads to make assembly easier? no you dont have to do that when you build your own coils, the wire is the same size all the way throughout unless of course your making claptons or any other fancy coil.

thanks, I see!

Two reasons off the top of my head: one is that it allows them to make a parallel/multi-strand coil without having to run multiple wires to the contact points. The other is that they will use a non-resisting wire for the lead to the actual coil wire, which gives better control over the resistance with certain types of wire like nickel and titanium.

Those are non resistance wire ends welded onto resistance wire.
Some older rebuildae attys used this type of system.

No, you don't want that for rebuilding coils.

I will be using kanthal a-1

i assume your not trying to rebuild a BVC or coil head? is this for an RBA ?

The welded ends are non resistant. These types of premade coils are used for rebuilding coil "heads" like protanks and such. The legs do not heat up like the resistance part of wire in the middle, and help with reducing the chance of melting rubber grommets (what holds those types of coils typicaly)

no. it is for a kanger protank 3

Protank 3, no need as long as you pay attention to build. Tanks like Ithaka - absolutely, to control heat at the coil, not down the legs.

I use these wires to rebuild my Evod atties because I've read, and believe, that they conserve battery power in my little 650 mah ego/Evod batteries.
Most of the battery power used goes directly into creating vapor in the coiled area rather than uselessly heating the long legs in this type atty. Also makes the rubber grommet at the bottom of the atty last longer by not being exposed to so much heat.
