Someone's selling this welder $200, was wondering if any of you could identify it/ give me any info on it. I believe the bottom unit, the welder, is a Powerkraft by Montgomery Ward. I don't know what the other two boxes on top are though. She said one of them says something about high frequency, TIG maybe? Said there were no tanks hooked up to it though. It's an hour away and with diesel prices I didn't want to make the drive unless it was worth it.
