1. Product Information: - Material: It is mainly made of plastic, which is strong and durable. The copper soldering pen is equipped with a 10AWG silicone wire and a protective cap for safe use. - It has an indicator light, a battery, and can be continuously charged with thousands of charging points. The 0.1 - 0.15mm nickel sheet can be fully charged with low power consumption. - Function: Self - detection function. When the soldering pen touches the nickel sheet, it automatically turns on with a response time of 0.8 seconds. It is well - made, has stable performance, and a long service life. - 6 - level adjustable: The output power can be adjusted in a 6 - level, 1 - 6 - 1 cycle for more precise welding. - Dimensions (Length x Width x Height): Approximately 5.51 x 3.15 x 1.57 inches; Package includes: 1 x spot welder with 2 soldering pens; 2 x soldering pen sleeves; 1 x nickel sheet; 1 x USB charging cable. 2. Specifications: - Welder - Material: Plastic, board, copper - Color: Black - Dimensions (Width x Depth x Height): Approximately 140x80x40mm / 5.51x3.15x1.57 inches - Power supply: 3.7V, 500:0p> battery - 1 - 6 gears - Welding thickness: 0.1 - 0.15mm - Charging input port: micro USB - Charging time: Approximately 4 hours - Package includes: - 1 x spot welder with 2 soldering needles - 2 x soldering needle sleeves - 1 x nickel foil 3. Test Step Instructions: - First, press and hold the power button for 3 seconds. After hearing the beeping sound, the device will turn on. There are a total of 6 gears. - When the device is turned on, short - press the button. After hearing the beeping sound, switch the lamp flashing level and increase the number of operations. The number of flashes indicates the gear level. To count accurately, press and hold the button and wait for the next flash interval to start counting. - If the above test is valid, press the soldering iron towards the welding object. After hearing the beeping sound, it means the soldering iron has made contact. Wait for about 1 second to start welding; if there is no beeping sound, press the soldering iron again. - It is recommended to place stainless steel/iron products on the workbench for spot welding during the test. 4. Notes: - 1. Consumer products are usually charged before the battery is received to ensure it is fully charged. For the best results, it is recommended that the first charging time be more than 12 hours. - 2. This machine can weld 0.1 - 0.15mm nickel - steel sheets and 0.1 pure nickel sheets. Materials with good conductivity such as pure copper cannot be welded. - 3. Do not use the battery for a long time or use an oversized battery. - 4. If the power is too low, the microcontroller will not work. Since the device cannot be turned on and the charging light does not light up, in this case, charge the device, and it will resume charging after a few minutes. - 5. We recommend placing the workbench on stainless steel/iron during the test so that you can see clearly. 5. Maintenance Suggestions: - 1. Please fully charge the device before the first use. - 2. If the battery is low, the functions may be impaired. - 3. If it is not used for a long time, charge it at least once a month. 6. Main Battery Life: - Made of plastic, strong and durable. - The copper soldering pen is equipped with a 10AWG silicone wire and a protective cap for safe use. - With a battery and a charging indicator light, after being fully charged, it can continuously weld thousands of points on a 0.1 - 0.15mm nickel sheet with low power consumption. - The automatic welding function: for nickel sheets, with a response time of 0.8s. It is well - made, has stable performance, and a long service life. - 6 - level adjustable: The output power is adjustable in 6 levels, in a 1 - 6 - 1 cycle for more precise welding.
