Recommend Spot Welder
I have a portable spot welder I bought to connect nickel battery tabs. It was garbage and would only weld a couple tabs before being too low energy to make an OK connection. I don't even consider them that ok. Then it died.
All the highest rated spot welders on Amazon are portable. Then there's bench welders that all have lower ratings and are about 4x the price.
No reviews say they can weld 2mm nickel reliably.
Anyone know of any product capable of making good welds on battery tabs? Seems like the market is flooded with junk that doesn't work and there's nothing at any price for consumers.

I only see this, which is suitable for joining sheet metal or something, but wouldn't be capable of joining battery tabs

What -- exactly -- are you trying to accomplish?

So the pincer-style spot welder is right out. Try renting the style in #2.
Have you considered a laser?

I did see something on Alibaba marketed as an untrasonic welder for $8,000.
When I say I'm willing to pay any price, I mean any reasonable price for achieving the correct temperature for the correct duration to sufficiently fuse nickel with steel.
*Oops, just realized I've been incorrectly saying zinc instead of nickel. Corrected. |
