The Lincoln 180 Transformer units are a solid 130 amp output 1/4" machine. Very capable. They will be discontinued. Not sure why but I think the tranny machines are starting to cost more to build than the inverters that easily go 115/230v and multi process that it seems like the "people" want. I've sold and owned a few of them that started out as an SP130 230v. Then the goofy numbers thing happened with all brands where they up the model number but the output stays the same. 180 is really a true 130. $599 is a pretty good price. I think that's what the 130's were back in the early 90's
