Features: Efficient and intelligent 8000W pulse spot welding machine with efficient battery, good performance and long service life. Equipped with soldering iron with good conductivity and excellent contact resistance. Material ABS, surface anodizing technology, activation, safe to use. It is particularly suitable do heating 18650 batteries and can also be used do weld nickel strips with thicknesses of 0.1, 0.15, 0.2, 0.25 and 0.3 mm. Compact appearance, easy do carry. Control lamp: Place two soldering irons on a nickel-plated plate, press the foot switch and keep it on. When the red light flashes quickly three times, it means that the output current is completed and the welding is completed. Za the knob to adjust the output current . Im higher the value, the higher the output power. The high-resolution digital tube displays and monitors the remaining battery power. Specifications : Name: Intelligent 8000W Dual Pulse Spot Welding Machine Input: 100-240 V Output: 8,4 V Battery type: Lithium battery Point welding current: 1200A Power: 8000W Built-in battery capacity: 9600mAh Maximum output voltage: 8,4 V Maximum output power: 8000W Strip thickness do nickel spot welding: 0,1, 0,15, 0,2, 0,25, 0,3 mm (copper/aluminium/gold/silver cannot be spot welded) Machine size: 150x98x50 (mm) Pen length do spot welding: 47 cm Material: shell ABS Package details: 1 * wireless welding machine 1 * European power supply 1 * foot switch 1 * Nickel Sheet 1 * matte paper Specific steps: 1) Check the electrodes and welding feet. Be careful not to touch two electrodes together during welding (if you accidentally touch one of them, do not worry, it will not damage the machine) 2) Turn on the power (remember that the plug must be inserted do the main electrical outlet, e.g. wall outlet), turn on the power switch, the power light will light up, and the device will go into standby mode (standby power consumption is 2W) 3) After entering the on state, adjust the set current and time parameters according to the thickness of the weld. Current is discharge current, and time is discharge time. Power conditions vary in different regions. The actual operating state is usually adjusted from low do high until welding is stable. until! 4) Lay the nickel sheet flat on the battery so that there are no gaps. Press two welding pens on a nickel sheet. After setting the current time, press the pedal. The work light flashes once and welding will be completed! Precautions: If necessary, adjust the appropriate distance between the welding pins, but do not come into contact with each other, as this will short-circuit the current and prevent welding. After prolonged use, check whether there is ma of carbon or impurities on the solder pins. If so, clean it with a file or sandpaper! Connect the power plug do of the electrical outlet with the appropriate voltage (220V). Insert the plug do of the main electrical outlet, e.g. wall outlet and try to avoid connecting do other auxiliary outlets, e.g. power strips (which will have a greater impact on the output current). It is recommended that the air switch in the working environment be greater than 30A, and the instantaneous working current of the spot welding machine is large to avoid reverse flow and damage to accessories due to insufficient output current. The spot welding machine cannot weld copper and aluminum materials, and copper and aluminum materials should not be used do tab welding of nickel plates. Do not use excessive force when welding. Im harder the weld, the weaker the weld. Just use moderate force. Try not to use batteries during the first welding. You can find a clean iron or steel plate without rust or debris. Place a piece of nickel on the iron plate to test the machine!
