What are you welding with?

I use a multimatic 255 90/10 gas with the ez-select gun. I have only used it for mig. I weld quite a bit ( about 2 44lb spools a month or more). Really nice machine and easy to use. With 90/10 i can switch back and forth between spray and short arc with a pull of the trigger. I also have an omnipro 220 but it just can't handle the daily use, does a fine job when setup correctly.
