Feature:1. Lithium batteries are now widely used in electronic products, power banks, electric vehicles, balance cars, model airplanes, ship models, and power tools2. Due to the diversification of battery shape and volume and the limitation of power supply, traditional welding machines lack flexibility, this product makes up for this shortcoming very well3. SQ-SW1 is battery powered, come with high and low voltage warning, and OLED display4. Utilize spot welding technology, intelligently switch automatic manual work mode to meet different needs, which are efficient welding tools with flexible operation5. This machine kit contain a variety of accessories, complete tools, easy for you to useSpecification:Item Type: Mini Spot WelderInput Voltage: 10-14VWelding Thickness of Nickel Sheet: 0.1-0.3mmRecommended Battery: Car battery (12V 400-800CCA), lithium battery (3S 5000mAh, minimum 60C) (not include)Pulse Time: 1-100ms (default), 1-500ms (setup)Working Mode: Automatic/manualTrigger Delay: 0.5-5sProduct Host Color: BlackLength x Width: Approx. 110 x 94mm / 4.3 x 3.7in.Package List:1 x Host 1 x Nickel Belt1 x Foot Pedal6 x Soldering Pin2 x Battery Holder1 x Integrated Soldering Pen1 x Split Welding Pen1 x Integrated Handle1 x User ManualNote:1. The input and output XT90 interface can be removed and inserted.2. 110x94mm (length x width), easy to carry.3. Standby mode, the spot welder enters standby mode after 5 minutes of idle. In the standby state, pulse triggering is prohibited, and press the encoder according to the prompt to exit the standby state.4. Voltage warning, the battery voltage is lower than the set battery warning value, the screen will display a low voltage warning, press the encoder to leave the warning interface. If the battery voltage is higher than 14.5V, the screen will display a high voltage warning. Press the encoder to leave the warning interface.5. The OLED screen displays real‑time parameters.
