Identify this welder???

[aaxiss]

I know this is the Everlast forum but I figured since The welder pictured is being replaced by a Powertig 250ex I could post this. LOL

I inherited this welder a few months back told that it works but I am too nervous to even plug it in and try messing with it without having it checked out by a certified tech first being it's in rough condition. I believe it's a 250 amp ac/dc hf unit but the model name and number has worn or eroded away lol. I am just going to try and sell it as is on craigslist but it would be nice to know the Model or the welder I am trying to sell if possible.

Here it is in all it's glory
