Question Help to identify welder please

Hi
Years ago, I found this old Wisconsin VF4 hand crank engine and welder unit sitting in a scrap yard. I bought them, thinking it would be kinda cool to get running (not my best decision). I finally got the engine running recently (that process would be a whole other thread) and last night attached the two back together to try the welder out. I got spark and a very short bead but ugly, almost like not enough volts. I tried various rods and moved the dial through its range but there was not much difference. All of the images I have been able to find show direct coupled units so I suspect this belt driven unit might have been built up by someone. I do have all of the shrouds for the engine, they are just off while I was working on it.

The engine running before I connected the welder is here if interested https://youtu.be/WSA8Uue4Cag



Sooooo, couple of questions, not process related but hoping that some of you that have been around for a while might know.

Any idea what make of welder it might be? I can find no tags, labels, numbers or any identifying marks on it anywhere, and I have had it flipped over while checking it out. It has a large coil in the base but no diodes anywhere so it must be only AC.

I have heard of "flashing" units that have sat for a while to restore some of the magnetism. How do I do that? How long do I keep the battery connected for? There is an H and L on two of the 3 connections, the third being "Gnd" so do I need to flash both the H and the L?

Thanks in advance
Shawn
