Mig welder questions

I purchased a Millermatic 211 for auto work and I love it. I'm not a professional.....just an enthusiast. I wanted to learn how to weld for many years and finally signed up for an evening welding class at out local Career Technical Center. I would recommend looking into something like that if it's available in your area. You have the ability to try different welders and have in instructor to critique your work.
It's wonderful having welding skills when working on these cars.
