If you touch the tip at 2372F you won't feel it but for a second before the nerve endings in your skin are killed by the heat.

Same thing happened when I got drops of molten lead on my skin while casting bullets for reloading. It doesn't hurt as much as you think because the nerve endings have been cooked. Also leaves a nice scar.
