Features:   1.16 flat high-power copper wire is soft and does not heat up for a long time  2. Weldable 0.3mm: easy to weld 0.2 pure nickel, 0.3 nickel plated, 0.4 stainless steel (unit millimeter), the solder joints are white and bright but not black  3. There is no problem with the actual test spot welding of 0.1-0.3mm nickel plating of the product, and 0.2mm pure nickel can be welded, and the heat of continuous spot welding is not obvious. The welding power can be adjusted from 1 to 120 gears.  4. Farah Capacitor Spot Welding Machine: Simple to use, easy to use, with my assistance, Xiaobais second spot welding Dashen board comes with constant current and constant voltage charging and capacitor equalization functions  5. The digital display control parameters are intuitively visible     Description:   This spot welding machine is powered by two imported Farad capacitors,controlled by high-performance MCU,and supports functions such as automatic working mode,output power adjustment, delay setting, circuit board temperature monitoring and high temperature reminder.     Specifications:   Name: Farad capacitor spot welding machine  Soldering Pen: Detachable Replaceable Soldering Pen  Input power supply voltage: DC12V 4A  Operating temperature range: 0& 8451;~+75& 8451;  Farad capacitor capacity: single 2.7V 3000F  Shell material: ABS  Optional Specifications: EU/US  Welding thickness: 0.2mm pure nickel, 0.3mm nickel plated, 0.4mm stainless steel     Precautions:   1. For the first use,itneeds to be charged for 20 minutes, and the spot  welding can be done after the voltage is charged to more than 5V.  2.Please start the test from the 1stgear before using it, and gradually  increase it ifit is notenough. Start the test from the small gear to the  large gear gradually.  3.The correct operation is to press thetip of the pen against the nickel  sheet with some force during spot welding.  4. Donot perform spot welding after unplugging the power plug, it will  damage the machine  5.Turn offthe main switch when not in use, no need to discharge the  capacitor, just store it in a dryenvironment  6. Itneeds to be plugged into the power supply and cannot be used after  the power is cut off.  7.Non-professionals should not disassemble the casing     Safety Instructions:   Please use the power supply and accessories that meet the safety  standards. It is recommended to use the original accessories.  Please ensure that the two soldering pens are not in contact before  turning on the power of the machine.  After use, the machine should be turned off and stored in a place that  is not easily accessible by children.  For the first use, "Power" is set to the default 5ms for spot welding.  According to the actual welding results,  Gradually set the appropriate pulse time toobtainagood spotweldingeffect.
