Doing temp control on a dna 200 with 316L when building low

[Chris1112]

So yesterday I decided to get some 22 gauge 316l from lightning Vapes so my first build ohmed out at .13, I downloaded the CSV file from their website for the wire and uploaded it to my device, I got to say freaking temp control won't even work I even went on steam engine and did my own CSV file for the size of wire and the wraps I used I can't get this damn thing to work right I even tried building another coil at Ohms out at .15 my current build is a 22 gauge 9 wraps on a 3.5 millimeter bit.. I'm just wondering if it may be too low I thought the minimum for dna was .08?

dna will handle TC down to 0.1 ohm. Having said that, working with such low resistance is best accomplished with a wire with a high TCR like Ni. SS 316L has a very low TCR. It will not work all that well with such low builds. Remember, a low TCR means only small changes with heating, making it harder for the board to follow the very small changes of a low TCR/low resistance build. Generally I stay above 0.2 ohm on my builds. I believe the spec on wattage/power for Kanthal is 0.2 ohm.
