heat - Formula to calculate heating time of nichrome?
https://electronics.stackexchange.com/questions/494682/formula-to-calculate-heating-time-of-nichrome
Thermal resistance for the nichrome rod (thick wire) will have two components: - from the wire to ambient, θ (ja) - from the wire to its holder, θ (jb) Both θ (ja) and θ (jb) are in units of deg. C/W. You will also need to know the thermal rise per unit length of your wire given a current input, which you can get from the manufacturer.

With your 38Ω piece of wire (Straightened out, not coiled) to 400°F, that is ~26V ( not including resistance changes ). (0.68 = 26V / 38Ω). 35°c is 95°F. That's slightly more than a fourth of 400°F. So try cutting the current to a 5th of that. 0.68 / 5 = 0.136. V = I ⋅ R V = 0.136 ⋅ 38 = 5.168 V Try 5v.
Properties of Nichrome Wire - Science Struck
https://sciencestruck.com/properties-of-nichrome-wire
Due to its relatively high resistivity and resistance to oxidation at high temperatures, nichrome is used in heating elements built inside hair dryers, electric ovens, and toasters. For such purposes, the wire is generally wound in coils, which when subjected to electric current, produces heat as a result of its high electrical resistance.
