Errrr not exactly. Short circuit actually balls and shorts breaking the arc at a ridiculous pace. It is different then globular and spray. Flux core burns in an open arc much like 7018 rod. As for the current it maintains constant voltage per the setting. Amps however is a function of the available wire....in turn this current density. That's why after so many volts per say it does no good to keep turning it up per diameter of wire. The wire can only handle so much. Saturation occurs and no better work is being done. So how do you get more amps?....More wire speed. More available arc carrying electrode equals more current density. So in reality if you want more heat you got to feed more wire.
The short answer was less stick out equals less voltage drop from resistance. But yes CTWD should be about 1/4 of an inch average in Short Circuit GMAW.
