PCB circuit board Spot Welder Pen Accessories Buzzer Mini DIY Replacement Useful
Product description:
Through the output of the MOS tube, the energy will be concentrated at the end of the soldering pen and will be heated by a short circuit.
Firmly fuse the nickel sheet with the battery.
It is precisely controlled by the MCU program without triggering the switch.
It is fixed with screws, which is more stable and reliable.
The welding current is about 90-130A, which is enough to weld ordinary 0.1mm-0.12mm nickel plates.
Upgraded to automatic trigger design, no longer need to press the button for a long time, completely liberating your hands.
Power requirements:
It is forbidden to use the power supply of farad capacitors, and it is forbidden to use lead-acid batteries or lithium battery packs above 60A.
System voltage: 12V-14.6V (capacity X rate = must be greater than 150A)
Current requirements: instantaneous output of 150A or higher (for example, car starter power, 3S RC high-power battery pack, 20A lead-acid battery with performance over 20A)
Misunderstanding: Don't think that the 3  series can supply power. The traditional  only has a discharge rate of 3-5C, so each part can only provide
2.5A * 3 = 7.5A load capacity, which is far away from 150A, unless 20 parallel, 3 series and 60650  divisions are possible, but this is obviously unrealistic.
The battery pack that can start the car can basically meet the power requirements of the circuit.
Battery recommendation:
20-45ah lead-acid battery with good performance and small internal resistance
3.5-5.5ah 3S model airplane lithium battery pack around 45C
30-35ah capacity  battery pack
Switch function: long press the switch for 1.5 seconds (green light flashes, output low power spot welding pulse every 3 seconds), long press the switch for 1.5 seconds (blue light flashes, output medium power spot welding pulse every 3 seconds), press the switch for 1.5 seconds ( The red light flashes, and high-power spot welding pulses are output every 3 seconds) Press the switch for 1.5 seconds to turn off.
