Features: Five-level power adjustable, four-level power display. Simple and convenient, powerful. 5V charging, it can be soldered more than 800 times once fully charged. Nickel tape is delivered to the spot welding machine, which can be held with one hand and is easy to use. Anti-short-circuit design, if the welding head is short-circuited, only one welding output is output, and the next output can be output after disconnecting again. Support 0.1~0.15mm thick nickel sheet, support 0.2mm nickel sheet welding in fully charged state, intelligent identification, automatic welding, simple and convenient operation. Notice: Copper and aluminum surfaces cannot be welded, rusted surfaces cannot be welded, and smooth stainless steel surfaces can be welded normally. One electrode of some batteries is stainless steel and the other electrode is aluminum. Our spot welding machine can weld stainless steel electrodes, and aluminum electrodes need ultrasonic welding. Please pay attention. Again, aluminum electrodes and copper electrodes cannot be welded. Common round batteries such as 18650 and 32650 can be welded. The two needles are pressed steadily on the nickel sheet to output welding, lift up, and then weld the next time. Welding method: Check the welding head visually, hold it at 60 to the horizontal plane, press the two needles on the surface of the nickel sheet at the same time, and the contact is good, the current flows from one needle to the other needle, and the high current melts the nickel sheet, Thereby, the battery and the nickel sheet are welded successfully. Spot Welder Operation Guide: 1. Short press to power on, long press to power off, and no operation for 6 minutes will automatically power off. 2. Support nickel sheet thickness 0.1-0.15mm. 3. After power on, the product is in automatic welding mode, welding once every 2 seconds. 4. When the welding head detects that it touches the metal, it can output it once, and then lift it up to weld the next time. 5. Ensure that the battery welding surface is free of rust, clean and flat. 6. Make sure the nickel sheet is clean and flat. 7. Set up the spot welding machine and press it properly so that the welding pin and the nickel sheet, the nickel sheet and the battery are in good contact, and there is no dangling and no bad contact, so that the welding can be done well. Different nickel thickness, different gears are not the better the effect of higher power, users can try which gear is more suitable. 8. Use Android mobile phone charger to charge, 5V input (higher voltage is strictly prohibited), charging current 1A, it is recommended to use 5V/2A charger. This product supports use while charging. 9. After turning on the machine, the output power of the spot welding machine can be changed by short pressing the button, and the blue light indicates the gear. Switch Machine: Short press to power on Long press to power off 6 minutes without any operation will automatically shut down Welding parameters Maximum output current up to 1200A Fully charged for more than 1000 continuous welds Five gears of power can be adjusted, short press the button to control, blue light indicator Charge: Use Android mobile phone charger to charge, 5V input (higher voltage is strictly prohibited), charging current 1A, it is recommended to use 5V/2A charger This product supports use while charging Remaining power indicator: green (high), green flashing (medium high), red flashing (medium low), red (low), red light must be charged before it can work. Low battery will affect the welding effect Please understand because of the light irradiation or computer display difference, so I can't guarantee photos and real color is 100% Package Included: 1pc of Spot Welderx 1pc of Nickel Strip 1pc of Manual
