Sunkko 796SD is designed for people who intend to welding copper wires to nickel strip or other small metal projects. It has a significant improvement in LCD and design of fixed welding head compared with SUNKKO 709 series.

There are two options of welding pins for users' requirements.



Welding Thickness: The huge power output enables 796SD to weld copper wires which diameter ranges from 0.3mm to 0.5mm easily to metal projects such as Li-Po battery packs and mini motor. This welder can also weld nickel sheet or stainless steel sheet to your metal projects, and the welding thickness ranges from 0.05mm to 0.6mm.

Two Ways to increase the power output: welding current and welding pulses.

LCD Display: The welding current and pulse can be easily set. Based on 709 series LCD, we added an extra part to show the dynamic welding current and pulse quantity 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.

Auto Cooling Fan: For the users of continuous spot welding, a temperature sensor is built-in, the cooling system will work automatically according to the internal temperature of the welder.

The 796SD battery spot welder can work with our professional spot welding table, making your battery spot welding and DIY process more smooth and efficient.
