My old Lincoln 225 amp, AC buzz box is getting tired. The amp selection switch is getting funky and hard to adjust in the low ranges. Its been good to me tho and I've used it hard more than once. One of the things I never liked much about it tho is the 15 amp increments between amp settings. I'm thinking I'd like to replace it with another machine. The criteria for the new machine follows It must be a stick welder (I've got a Lincoln 110VAC wire feed) AC/DC Copper windings---not aluminum amp range up to at least 200 I know Lincoln makes a machine with all the above criteria but I'd also be stuck with the 15 amp increment in the selector switch. Miller makes a similar machine with a selector switch that can be more closely zeroed in. Are they any good? Any other suggestions?
