Which Mig welder to buy?

found a lincoln at the depot on clearance they said it was used , not a mark on it or in the tip . never had a lick of trouble . used to have a silver beauty brand in the early nineties, had to get a liner for it , come to find out same liner assy that a miller . some of the smaller outfits ive seen use some of the larger outfits internals , besides the liner never had a lick of problems with it either . had 120 and 220 if you have the power go with the 220 , i even made an extension cord for mine works great . ed aka dartman 440
