797DH is the professional-level model of battery spot welding.
Applicable to weld 18650, 14500 and other lithium batteries.
Two ways of welding: fixed welding head and mobile welding pen, must be used with foot pedal.
Press the button and adjust the knob, machine's power is changed conveniently.
Three types of welding pens(70B, 71A, 71B) are available.
The built-in LED light helps you work at night.
Please read the manual carefully before using.
fixed welding head: 0.05-0.25mm pure nickel strip or 0.05-0.3mm nickel plated steel.
mobile welding head: 0.05-0.15mm pure nickel strip or 0.05-0.2mm nickel plated steel.
The welding current 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 number during the welding process in real time. 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.

1. Sunkko welding machine can be used to weld the pure nickel strip, nickel plated steel, nickel plated iron, iron and other alloys, but it cannot be used to weld metals like copper and aluminum.
2. The machine must be powered by wall outlet but not the platoon insert.
3. The surface of nickel strips and batteries should be clean enough, dirty surface will influence the welding effect.
4. If home circuit breaker trips after switching on the machine or welding with high current, a new 40-63A circuit breaker is needed for replacement.
