price reduced, make an offer, I have a used Lincoln DC -400 for sale, I also have 1- Lincoln LN-7 for sale, I bought these at an auction where I was told the DC-400 was single phase power, it is not. It requires three phase power. Therefore I'm not able to use it since I don't have three phase power. im asking $1,500 OBO for the DC -400 and $200 for the LN-7 I would consider trades for a good mig welder that uses single phase power.
