A reader named John sent in some pictures of an old Birdsell Welder that he had acquired. He’s looking for any information about it, so if any of you know something about this machine, please leave a comment or contact me and i’ll pass the information along. There doesn’t seem to be much on the internet about this company. I did find a Birdsell Mfg Co, Inc based in South Bend Indiana that manufactured farm machinery, but i’m not sure if it’s related to this. So, if anyone knows anything, we’d love to hear about it!
From the data plate:
