788 series features battery pack charging function.
788H has the additional battery pack testing function but no USB charging ports.
788H can charge nominally 4.2-30V battery pack and test the actual voltage of battery pack below 50V.
Applicable to weld 18650, 14500 and other lithium batteries.
One way of welding: fixed welding head, welding with foot pedal is optional.
Press the button and adjust the knob, machine's power is changed conveniently.
The built-in LED light helps you work at night.
Welding thickness: 0.05-0.15mm pure nickel strip or 0.05-0.2mm nickel plated steel.
Please read the manual carefully before using.

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.
