Posted 9/10/19 at 4:26 pm ET: I have a vintage or antique (i.e. older) Lincoln Fleet-Arc Junior limited input welder. The unit is red, and is about 4 feet tall and 2 1/2 feet wide - it's big and heavy, but it's on wheels so it's movable. I don't know how old it is - I haven't been able to find anything online except pictures. According to the tags on the front, it has ARC striking control, is for normal sheet metal welding, has a maximum welding current of 180 Amperes, a maximum open circuit voltage of 52, a NEMA industrial rating of 125 Amperes, and it must be connected to a 230 volt 60 cycle line. The input is 37 Amps at 180 Amps welding. The patent number is S-7731. I would like to sell it, but I have no idea how old it is or how much I should ask. It would have to be picked up locally (central NJ) as it's too huge and heavy to ship. Can anyone give me more information on this? Thank you!
