What is the purpose in this ?

I usually rebuild/clean store bought coils, yesterday I ripped apart a SMOK Q-4 I think it is & noticed it has 2 different gauge wire. Just wondering why ? I hope you can see it goes from the thick 21 gauge ? 2 wire wrap to a 4 ? gauge wire then back to 2...
I took some pics Lemme know whatcha think..

Dang posted in wrong forum could a mod please move
Peace

My only guess is maybe the larger diameter wire is meant to go to the inside of the coil because it’s not in direct contact with juice like the outside is. The larger wire will ramp up slower than the thin wire. An attempt to make the coil last longer or not get dry hits as often.

Edit. After looking closer at the pics, I might be off a little lol

I think that is the Q2 not the X4

Its the V8-Q4 for the Cloud Beast tank

It looks to be non resistance wire to resistance wire back to non resistance wire.

This is how they're making coils now,and why its called "Q4" because its got 4 coils but only 2 neg and 2 pos leads..
I did some googlein
Another member here actually found this out with the "8" coil with only 4 leads

That's how MOST coilheads are made..... The legs are made of non conductive wire..... This helps reduce the occurance of hot legs in build that cannot be burned in and also promotes a better electrical connection.

if the coil wire itself is different it's to create a staged heater.
