What is going to heat up faster?

[JasonBourne]

So I read this on a thread a few weeks ago, but I cant seem to find it now. If I want my coil around 1.5-1.8 ohms is it really going to make a difference if I use 28gaug at those desired amounts or 30 gauge at those desired OHMs. Meaning is there going to be a difference which one heats up faster since they are going to be at the same ohms? Is it better for the coil to heat up faster? Also, I think I saw that the 30 gauge will heat up faster, so why do most people use 28 gauge on a rba. Thanks

The 30 will heat up faster but I'm not sure the difference will be that noticeable. Now if you were making 2 ohm coils with 32g and 26g the difference would be much greater. The 26g coil would need a lot longer piece of wire to get the same resistance and it would heat/cool much slower.

The gauge wire you use depends on how many turns you can fit into a given space. The more coils the better the juice atomizes. Smaller wire heats up a little faster than larger wire, but you are talking fractions of a second difference. I use 32 gauge Kanthal on my Protank coils and get about 6 coils in a small area with it for 2 ohms on a 2mm silica wick.

Thanks for your answers. Do you think it would be better for the coil to heat up faster or would that lead to more dry hits? Im using a vv so wattage output I could make the same with each coil, just wondering if it would be better if the coil heated up slower or faster and would it be better to have more coil wraps so more surface area, if that is the case then the Lower gauge would be better. Thanks

Build a 30g 1.5 ohm coil & a 28g 1.5 ohm coil and see which one heats up faster, and hits harder. (my vote is 30g)

For 1.2-2+ ohm coils I would suggest using 30g kanthal.

For 0.4-1.1 ohm coils I would suggest using 28g kanthal.

Right on the money I'd say that 32 gauge becomes useful above 2.2 ohms and 26 gauge below 0.6 ohms.
