love my little lincoln 140c the real version NOT the chain store offered unit . she is a tank and i have done some 3/8" welding with just a little pre-heat to be sure and a good bevel to help get a fat bead .
the chain store version are around 500 buck range and weight around 55lbs .
the REAL version from lincoln dealers or order specific are almost 900 bucks and weigh 77lbs .
this 110volt unit is amazing from a lot of others i have used over the years . i have had a hobart 140 / used miller but in the end i have just gotten deals on lincoln's . the lincoln 140 is infinite adjustment on both power level and wire speed so you can dial it right in .
yes i have bigger but i sure do use this little guy a lot . here is my welder family 140c / 216 power mig / precision tig 275 and my hypertherm xp45 plasma
