Summary

 

Sunkko 797DH is designed for people working in battery spot welding 

business. It has a great improvement in LCD display and design compared 

with sunkko 709 series. 

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 0.3 mm for nickel plated steel or between 0.05 and 0.25 

mm for pure nickel strip. 

 

 

LCD DISPLAY

: The current level and pulse can be easily set. On the basis of 

sunkko 709 series LCD, we added an extra part to show the dynamic welding 

current and pulse quantity during the welding process. The value at the lower 

left corner stands for the dynamic welding current, 0.1 equals to 100 amps. 

The value at the lower right corner is the dynamic pulse quantity. The right 

pulse quantity will be displayed after the first welding when you adjust the 

pulse buttons. 

 

MOBILE WELDING PEN

: Sunkko 797DH gives users more possibilities at 

work, 797DH can be compatible with 3 types(71A, 71B, 70B) of mobile 

welding pen, and with our professional spot welding table, making your 

battery spot welding and diy process more smooth and efficient.
