The input power ( 25 Amps at 240V ) is 6KVA. I would guess that it is at least a 200Amp welder, maybe 220. It has 24 power settings ( 4 x 6 ), and timers for stitch welding. It is a very early Eland, possibly made in England; later ones were ( are ? ) made in Hungary. Due to the outer condition it looks a little rough, and you might only get 200 Pounds for it. But it is worth at least double that, and you will never buy anything comparable to it today for that money. So, don't sell it !!
