DIY PCB Circuit Board 4MOS Welding Equipment Portable 12V Battery Storage Spot Welding Machine with Spot Welders Pen for 18650/26650
Shipping:Standard Shipping about 10-25 business days
Lithium battery, advantages:portable, stable and reliable, and durable.
Users need to supply 12V battery power, welding current is about 90A ~ 130A, for the common 18650/26650/32650 0.1mm ~ 0.15mm nickel plated welding. After several generations of product updates, it is now upgraded to automatically trigger the welding, liberating the buttons of the fingers.
Switch function:press the switch for 1.5 seconds to switch (blue light:low power, green light:medium power, red light:high power)
Power supply requirements
System voltage:12V-14.6V (capacity X rate = must be greater than 150A)
Current requirements:150A or more instantaneous output (such as car starter power supply, 3S RC high-power battery pack, 20A lead-acid battery with good performance above 20A)
Misunderstanding:Don’t think that you can use 3 series 18650 series to supply power. After all, the conventional 18650 only has 3-5C discharge rate, so each section can only provide 2.5A*3=7.5A load capacity, which is far from 150A unless 20 Parallel connection, 3 series and 60 sections of 18650 are possible, but it is obviously unrealistic.
1. it is equipped with a 3.7-4.2V 4.5ah power lithium battery with a discharge rate of 100C and a load capacity of about 400A.
2. Through the MOS tube output, this energy will be concentrated at the end of the welding pen, and it will be heated by short circuit.
3. Fuse the nickel sheet firmly with the battery. All this will happen in milliseconds,And it is precisely controlled by the single-chip microcomputer program without trigger switch.
4. Free your fingers or foot pedals completely.
5. Comes with a charging control module, which charges the battery through the USB port, and is charged with hundreds of welding points on commonly used nickel-plated sheets within 0.1mm-0.15mm.
