welder flux to mig???

you can get the kit at most welding supply shops for about $150. it comes with all the lines, regulator, and liner. just no bottle but you can rent one from the welder supply store. also there is only one flux welder I know of that you can't convert to MIG and that one is commonly called the handy core welder. it is shaped like a rectangle and only has two heat settings. what is the model you have?
