This may be a dumb question but are these being used for dual
coils for instance a Innokin i16?
There are no dumb questions, just some dumb people who don't ask questions.
The iclear 16 does need to use non resistance wire attached to each end of the coil, so yes, a wire welder could be used to join the non res. wires to the res. wire.
That being said, the iclear is rather difficult to rebuild, it seems not many people are doing it. It's a cramped space to get the four wires into and the non resistance legs have little plastic sheathes over them so the wires don't touch anything they're not supposed to. It could be put together probably without the sheathes, but you'd have to be confident in your ability to keep the wires from shorting.
If you want to give it a shot and the iclears are the only thing you would use the welder for, I would suggest getting premade wires to start off with, then you would'nt waste the money on a welder if rebuilding them did'nt work out. What's the total ohms you want to end up with, or do you want to experiment ?
