Product Features
- The newly designed U.S. Solid USS-BSW00007 high-frequency inversion battery spot welder equips with the two super capacitors for energy storage and power supply for pulse welding. Unlike traditional bulky AC transformer spot welders, it is more portable and it does not cause any interference to the electric circuit, eliminating tripping problems.
- The low-consumption super energy-gathered millisecond pulse technology maximizes the pulse energy output in millisecond-level time, the welding spot is excellent and no damage to the battery.
- 21KW/3500A Super Welding Output - Supporting the large-capacity power battery of aluminum terminals welding.
- LED Display Screen & Controlling Buttons - Real-time capacitor voltage, power grade and actual welding current parameters are monitored. Convenient parameter adjustments can be made by pressing the buttons.
- ‘AT/MT’ Two Welding Modes - 'AT' automatic mode for quick welding and 'MT' foot pedal controlling mode for beginners or precise welding.
- Multiple welding pen accessories are available for different welding requirements. (Please notice that the package only contains the default 73B/75A welding pen for 18650/LFP lithium battery welding, additional purchase required for other-types welding pen).
- The newly added ‘AL-NI’ super power mode function provides a max welding current of 3.5 KA, 0.2mm pure nickel can be directly welded to the aluminum terminals of LiFePO4 battery, saving you the expensive cost of using aluminum-nickel composite strips.
