Spot welding Copper / Copper Nickel / Copper Stainless Steel Sandwich

Did some searching online and couldn’t find anyone else complaining about this type of behavior but it is a newer product so not necessarily a good indicator

I’d be interested to see inside too, but they have a 1 year warranty don’t they?

I didn’t see an easy way to look inside my p20b without a prying tool.

Seems something was lost in translation with that preheating response.

Does the double hit happen every 20 to thirty welds, only after getting hot from doing 20-30 welds at gear 400. Does it do it when cold?

They do have 1 year warranty. If that is a show stopper can be sent to factory for fix/exchange. I can help with the proces.
