I am trying to locate a source of information for spot welding. I acquired a Unitek 80F weld head, and a Unitek WS210X power supply but can find no info on the WS210 series. Unitek had no manual or info when I contacted them. I also acquired a Unitek 1000B but can find no info on it. I got them with the idea of making my own nimh battery packs. I have not found what footswitch I need. The 80F head appears to be strictly manual positioning and the contact is single contact so I am not sure how to move the second contact electrode close enough to do the small nickel strips that join each battery cell.

I looked for forums specific to spot welding but Google was not my friend on that.

Any pointers or info would be greatly appreciated.

Thank you.

You may want to change your search terminology to include "tabbing" instead of spot welding. That is (or was, anyway) the term more specific to joining on the lead strips to battery cells. I just did a quick Google search using "tabbing battery cells" and had three or more video hits turn up as well as a bunch of regular web pages. Give it a try, I think it might work better for you.
Good hunting!

I tried your suggestion but all I find for hits are places selling the nickel tab material or complete battery packs. What I wanted to find was a forum specific to spot welding and hopefully with an electronic slant as opposed to auto repair.

I have the spot welder or at least most of it but can't find any info on the Unitek Miyachi equipment. I have seen many web pages on making spot welders such as those using a modified microwave oven transformer. I also looked at some of the cheap spot welders on ebay in the $175 range but from what I saw the quality just was not there and they did not last very long.

Thank you.

Ah, I see. I didn't delve deeply into them, and I'm sorry to have sent you on a wild goose chase. Good luck!

Resistance Welding is the technical term you are looking for. This should open up a slew of technical information on the internet for you. If I can find it, I'll locate the Resistance Welding Handbook in pdf format.

EDIT: try this - Resistance Welding Handbook on Scribd
