Technical data: Name: Spot welding machine kit Material: Printed board Voltage of the week: 8-24V Operating current: 20 mAh Electric current peaks: 2400A max Power consumption in the initial power phase: 0,5 mAh Weld thickness: 0,1-0,2 mm Limit temperature: 175 Product Size: 89*54mm/3.50*2,13 inch Item Weight: 100g/3,53 oz Package Weight: 155 g / 5,47 oz Perfect gift for newborn parents, newborn mother, newborn father, baby shower, birthday, Christmas, festival and so on. The processing process involves the use of current power and high temperature, fast melting part of nickel plate and drawing. Fast single-chip design, intelligent program, displaying the battery voltage in real time and good resolution of spot welding force. It adopts 8pcs MOS pipes, the peak current is do 2400A, supporting 0.1-0.2mm nickel welding sheets, and the points are still solid and beautiful. The high-precision design of the output power with 99 gears output power is dependent on the purpose of the more accurate equation and allows you to achieve twelve points on nickel sheets and nickel sheets. With 3-bit real-time gear difference with digital pipe, which not only can display the current gear, but can detect the supply voltage and increase the pleasure of spot welding. Enabling a tube-shaped digital network alternately displays gear and power once per second. When an appearance appears: d two digits, it means that there is a pod gear display; when an appearance appears: three digits, e.g. 12,6, this means that the power supply of the power supplies is: 12,6 V power supply. Three operating modes, you can turn between general power mode, power amplification mode and superpower mode. Two point welding delay times are constant, 0s or 1s delay time can be set according to working requirements. It is both a spot welding machine and a voltmeter, a 12-bit ADC converter, a measurement of voltage measurement do 0,01, with test ranges of 8-24 V, automatic display of power supply when connected do power supplies. Flexible do spot welding, 12AWG wire consists of multiple strands of high-temperature wire with high quality for rotating and more sensitive operation. Thick pure copper welding pen design with do alumina spot treatment needles for high current throughput and durability. The process on large contact surfaces can be combined with pure copper to make internal resistance. You can choose one of the sources as the week of the power source: 1. Lead-acid battery: 2*20Ah electromobile battery, 36-405H new car starter battery. 2. Battery model: 3S 4000mah 35C, 3S 5000mah 25C, 3S 8000mah 20C. 3. Car starting materials: 11,5-14,8 V 36-60 Ah, internal resistance should be 2,5 millioms and 7 millioms. 4. Self-assembly battery: 11,5-14,8 V, total interior resistance 7 millioms.
