Battery Spot Welder with Pulse & Current Display 2.88KW

737G is equipped with dual pulse mode selection and 0 ~ 99 current level setting, which allow the machine to weld nickel strip within 0.03 ~ 0.2mm thickness (0.15mm for  pure nickel), making the spots more reliable. The combination of fixed welding head and foot pedal will meet users’ different welding requirements.

This spot welding device is suitable for building small lithium battery packs, and can also be used for building medium or large battery packs with S71A mobile welding pen.
