Sure, you don't just flip a switch to full current, the inrush can burn it out.
A requote from Abd, of course. But never mind.
Since the resistance of Kanthal Wire is not temperature dependent, there is no 'inrush current' - also the inductance/capacitance is very low so not much back EMF. The current when cold and the current when hot are pretty much the same. Inrush current is a problem in other situations, but not this one.
