I had a Miller 135 that I borrowed from My son, Than I just bought a Miller 180 Auto Set for myself it's a great machine.The only thing I don't like on some is that the settings for feed and voltage are set at 1 thru 10 and nothing in between where the Miller You can set it at 4.5 4.6 so you have the ability to fine tune you're welding to the task at hand the first welder I had was a Snap on with the click settings and I would burn thru on say 6 and it would be to cold on 5 with the Millers I've used I can set it for 5.5 to get the prefect weld.
