737B is equipped with dual pulse mode selection and 0 ~ 99 current level setting, which allow the machine to weld nickel strip within 0.03 ~ 0.2 mm 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 habits.
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.
