Electroweld Pneumatically Operated Battery Tab Spot Welder 5KVA @ 50% Duty Cycle (BSP-5P) (Weldability: 0.03mm-0.45mm, 26-49 SWG, 27-48 AWG)

Users Include: Users include manufacturers of custom battery packs, for battery pack rebuilding, battery cell tabbing, welding alkaline battery tabs, welding for lithium type cell.

Welding Functionality: The welding process consists of welding of thin nickel plates which connect one battery cell to another in a battery pack using the Battery Tab Spot Welder. This machine uses a dual pulse feature which produces a clean, strong and repetitive weld. The first weld heats the surface and eliminates the contaminant to seat the welding electrode tips. The second pulse produces a second strong weld.
