well i've had this i mig 200 for about a year now and i must say it's the best mig machine i've ever used. it welds better then the miller 180,miller 212, or lincoln 180's i've used in the past and more forgiving on the settings. i've never been able to weld 18 to 24 gauge with any of the other migs i've used but this 1 i was easily able to weld in all the new floorboards on my jeep without burning holes in it
