  • Page 2 Summary 737G+ is a big improvement on the basis of 737G. It is specifically designed for battery welding (18650, 14500 and any other lithium batteries, etc) and can be used to weld nickel strips with thickness between 0.05 and 0.35 mm for nickel plated steel or between 0.05 and 0.25 mm for pure nickel strip.
  • Page 3 Mobile welding pen with foot pedal(MT): The mobile welding pen effectively  extends your welding area, and this design is popular among electric hobbyist, because they can build large lithium battery packs for their e-bikes or other projects. Welding range: 0.05~0.2mm for nickel plated steel, 0.05~0.15mm for pure nickel strip;...

    (Attention: This spot welder can be used to weld pure nickel, nickel plated steel, nickel plated iron, iron and other alloys. It CANNOT weld metal like copper and aluminum.) Specification for welding part: Input voltage: AC 110 V/220 V±10% Welding current: 120 ~ 1200 A Single pulse time: 5ms Max.
  • Page 5 5. Do not short circuits during spot welding or charging. 6. Do not use Sunkko welders with a voltage transformer as Sunkko welders are not compatible with the common voltage transformers in the market. 7. Continuously spot weld too fast will speed up the loss of internal components of the spot welder.
