Do we have any resistance soldering gear?

Thanks.

Are you referring to a spot welder which might be used to attach tabs to battery terminals? If so, I think so. I saw something that looked like this beast, complete with foot pedal, in the electronics lab yesterday.

There is a new spot welder for battery pack connections. Resistance soldering is a different process. I’m not sure if any of the gear is dual purpose.

I was specifically looking for resistance soldering. Thanks for the answers.

I’ll take a look at my soldering station sunday and see if it has the resistance attachment. It is boxed up in storage.

We do not have a resistance soldering setup that I’m aware of. Maybe stuffed away in the many boxes we have not sorted.

I would think there ought to be some good build guides for resistance soldering set ups. I would think a MOT would be a good start, and with the skills and tooling we have, it should be possible. Copper stock for the tips/jaws is probably the most challenging part to aquire.

Tom, don’t spend the time doing that. I don’t have an urgent need. I’m just planning ahead for as yet unidentified project.

Thanks!

A lot of builds start with an old school 12volt battery charger. It’s the iron part that is tricky to get right. Or repurpose a Weller soldering gun with a finer tip.

What about a small welder? Looks like the key bit of this is a fairly stiff constant current source.

Who would be the right person to talk with to understand what I could or could not do with the spot welder for battery pack connections?

Thanks.

The battery spot welder can only do up to 0.1 millimeter strapping. Maybe a shade more. Either same side or through welds.
