I bought the Miller 252 ,not my first choice though ,i originally had a Snap on that is actually a lincoln . It was actually the best welder i had for light gauge sheet metal with stitch weld and spot timer . It was quite a bit more than the miller to replace so i went with the miller . The miller isnt as easy to weld light gauge but if you ad a tweeco gun it does do better. I hated mine untill i changed to the tweeco gun . Once you get used to the miller it does a good job. They do like very clean metal ,no paint or primer or rust ,the cleaner the metal the nicer the weld. The 252 is also a stick welder with a spool gun available ,that will be my next purchase
