General power settings dna 200

[Richard Hasal]

Sorry for the newb questions of late but I just bought this dna 200 device and I am completely fascinated with it. 
I’m using regular pre made drop in Kanthal coils at the moment ( can’t wait to get into TC ) but I was wondering if there is any benefit or in what situations would I change these settings from the default values. 

General/Power:
Kanthal power limit
Preheat power
Preheat punch

Hoping to learn

General/Power:
Kanthal power limit <- 'Your' manual limiting of max watts. 
Preheat power <- TC only
Preheat punch <- TC only

There are some good youtube escribe tutorials by pbusardo and djlsb vapes.
