you know, i havent pushed it to the point to where it shuts down on me(supposedly its thermally protected). i can run a couple 3"-4" beads, let it cool a little bit while i wire wheel the slag off and prep for my next weld etc and it's ready to go when i need it. of course i wouldn't mind having something a little more powerful with a better duty cycle, but you wont find a better wirefeed for $120
