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.
