Now SUNKKO has developed the 709AD+ model to bring you more business on Lithium battery packs with its intelligent mobile welding function (only for mobile welding pen).
The welding switch and the soldering switch are separated to make the machine more energy efficient.
For the users of continuous spot welding, a temperature sensor is built-in, the cooling system will work automatically according the internal temperature of the welder.
The new no-button interface makes the operation adjustment more smooth and convenient. The real-time pulse display also provides you the machine's actual welding status.
