Can I ask out of curiosity If you got or built a coil at say 1.5 ohms then after a week of use what would you expect that coils ohm reading to be , same - lower - higher ?
It might go a little higher as the oxidation layer on the Kanthal forms thoroughly, but it should remain about the same. If you're seeing big swings downward, you likely have a short, and if you see big swings upward, you probably have a loose connection to your post screw.
Hi PapaSloth and returning Doctors and everyone.
Still Wondering on the kayfun clone I got on the bottom the middle screw , is that some battery pin adjustment ?
Is it best to leave it alone ? As I read that someone turned it with s screwdriver and it shorted when they fired it up because the positive block touched the negative block.
The bottom middle screw (510 connector screw) attaches to the center block in your kayfun and is the only thing holding it on. When you turn that screw, the center block will either loosen, or turn. If it turns, it can easily touch another part of the evaporation chamber or the negative post, causing a short, so that's BAD. You want to tighten that screw with the center block held in place, so it's very snug. If you overtighten it too hard, you can actually snap the screw, because it's hollow and your air flows through it (so don't overtighten it too much).
There's also a hole drilled across the screw where the air comes in and runs through the hollow part. If possible, this hole should line up with your two air holes so that you can see straight through the Kayfun (this only applies to the EHPro dual airhole version, which is what you have). If you can do that without undertightening or overtightening the screw, that's ideal, but it's more important that the center block is very snug and that you don't snap the center screw.
