I am still running flux core because I dont have a bottle yet but I think best would be plan on setting up for gas than you can experiment with both. I would like to hear why gas is a stronger weld. I have heard you get more penatration with flux . If gas is stronger it seems it would be because it is a cleaner weld but I dont know that to be true.
I use a 25/75 blended gas, flux core for out side in the breeze.
I might add to this subject a little more information that I previously left out that if your having problems using flux core wire on thin metal to change your polarity from reverse to straight polarity, you will get less penetration, but also less blow through. You will likely have to do this,as the flux core wire is usually .030 or 035 ,and most smaller welders using gas,use .024-025 wire for thin material. Changing polarity is only a matter of changing your ground to the terminal where your torch connects,(-) and the torch connects to your ground terminal,(+).

have never tried that but never had the need as I've got two other welders....both gas 110 Snap on and 220 Century and honestly I use 30 in both....tried using 23/24 in the snap on but just seem to have better results with 30....
.030 wire takes a bit more power then .024-25,but i guess it's whatever works best for you. I think a lot is in how fast you move along with your torch speed also,(I tend to move slower then I once did,haha)Brian
i have welded for aliving for over 25 years. i use a miller 220 .045 flux core and 75/25 gas and will not use bare wire. splatter is low on the flux wire and the bare splatters alot. i use v-71 wire and yes it is used with gas.
