We are selling a Liburdi Dimeterics P300 Orbital Welder that is guaranteed to power on (That's the only testing I could do). It just came from the Lauren Engineering auction and it was kept inside and in its original crate. It was out on a job when they shut down, so my guess is that it works fine (They seemed very good about marking and separating the equipment that had issues). I am in Oklahoma City and if you are in the area and wish to test it please contact me. I will pack it in it's original box and pallatize it for your shipper to pick up.
