Thats what i was wondering , cost difference that is quite a lot of bucks floating around, As far as performance in his video if he did not tell you which machine he was using there is no way to tell. I guess you could throw the 160STH in there to get a little closer comparison but it is still a lot of difference on cost . My vote would be Everlast Vs Miller on this one, There is no apparent advantage on weld quality or function Just the fact the Miller is almost 5 times higher in cost .
