Kanthal Coils touch and TC coils are spaced yes?

[Harryinny]

So, before i run off making my coils, Kanthal coils are tight and touching while Ni,Ti,SS are all spaced so the warps are not touching right? That should get me on the right track. Got steam all set and got my numbers and ready to roll(play on words there see that?) lol

Thanks to all that have helped me so far on my journey on getting set up.

Now its building time(saturday) lol.

Kanthal can be spaced or contact, so can SS, but spaced works better in tc for SS. I use contact SS coils for wattage mode but it does not work in tc. Ni and Ti has to be spaced as you can't dry fire them to get rid of hot spots.

there are people who do contact coils for Ti and fire them at very low wattage to check for hot spots. you just can't get them glowing red hot or bad things will happen.

personally, i'm using spaced Ti coils.

Excellent advice. I have all those wires. Now, SS i wattage mode? What Ohm coils are you using and what wattage? Just incase i decide to try my SS wire to do wattage mode. Did not know you could. Yes, i do have my Ti wire and can not wait to get back to using Ti if SS TC doesnt work out. The Ni i am using right now might be the cause of me hacking and feeling like theres something in my right lung all the time since i started using a Ni head in my Kanger TopTank.

Thanks for the tips.

0.32 ohms max reading at 100w.

Harry,

I dunno if it is the case, but some people apparently have sensitivity issues with Ni.. would not be sure if that is the reason for your hacking... but you might wanna stop using it if you're experiencing that.

Contact coils are fine with SS, kanthal, and ti, provided they have an oxide layer.
You are partially correct about ti, but the color range you want to avoid while pulse firing to create an insulating oxide layer is at the top of the straw-colored range of heat, dull cherry is fine with ti. The oxides people worry about are only present as gasses at welding temperatures, which happen at the brightest range of straw. In ferrous metals, they will become nonmagnetic and sparks will start to jump off of the heated metal. Our coils will melt and become a nonviable path for electric current before this can happen.
Nickel doesn't form an oxide layer so you can't run contact coils without shorting. Nickel is best avoided, it is easily the most frustrating wire to work with.
