It has the option for gas as well. It came with 2 spools of wire, 1 flux core and 1 solid, I figure i will try practicing with the flux core. I havent priced gas out yet but its probably pricey.
PoisonDart74 that is a good idea with the dimmer.
Dovercrossing, I have left over 14/2 wire in the garage and was going to use it, but you are saying that 12/2(larger than 14/2) wont cut it???
