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.
Technical Detail Model: 709AD+ Power supply: AC 110V, 60Hz; Max. instantaneous power(fixed welding head): 3.2 KW Max. instantaneous power(mobile welding pen): 1.92 KW Max. welding current: 800A Welding pressure: 300 - 500 g Fixed head welding thickness: 0.03 - 0.3 mm Mobile pen welding thickness: 0.03 - 0.2 mm Welding thickness of pure nickel: 0.03 - 0.15 mm Welding pen cable cross sectional area: 16 mm2 Soldering iron temperature: 150°C ~ 450°C (up to 300°C within 7 seconds) Soldering station power: 50 W Output voltage: DC 20 V Requirement of Earth Leakage Circuit Breaker ≥ 40 A Net weight: 7.3 kg
Attention: This spot welder can be used to weld the nickel, nickel plated steel, nickel plated iron, iron and other alloys, but it can't be used to weld metal including copper and aluminum.
