I have a 225 amp wire feed welder. It is a flux core welder. It could be made into a gas welder I just went ahead and bought one that had been set up for gas. It runs .35 flux core wire. It is a good welder and does a fine job. The wire stinger is less than a year old. It is in great shape for it's age. If you want to try it out, before you buy it, that is certainly an option.
