Review on 🔋 GLITTER 801D Battery Spot Welder - 12 KW Energy Storage Spot Welding Machine for 18650, 14500 Lithium Battery Pack Building - Mini Portable Precision Pulse Battery Welding Equipment by Mike Sutton

They claim this welder delivers 11.6 kW and 60 joules but it doesn't. I believe 11.6kW is based on 5.3V x 2000A and 60J is 11.6kW x 0.005s. In fact the welder is only putting out about 1200A and 5.1V so 6.12kW or 30, 6 J. It will weld pure nickel with a thickness of 0.15mm, but 0.2mm is optimistic. I bought this from Aliexpress and the seller told me it shouldn't handle more than 1300 amps even though it was advertised as 2000 amps.
