12V Battery Energy Storage Spot Welder machine Welding Pen PCB Circuit Board M8
Product Features
  • Lightweight and portable, stable and reliable, wear-resistant, and can provides long service time.
  • Through the MOS tube output, this energy will be concentrated at the end of the welding pen, and it will be heated by a short circuit.
  • Fuse the nickel sheet firmly with the battery.
  • And it is precisely controlled by the single-chip microcomputer program without a trigger switch.
  • Adopt screw fix, more stable, and more reliable.
  • The welding current approx. 90-130A, which is more than enough to welding a common 0.1mm-0.12mm nickel plate.
  • Upgraded to automatically triggered design, do not need to press the button for a long time anymore, completely frees your hands.

    • Note
  • Power supply requirements:
  • It is forbidden to use the power supply of the farad capacitor, and it is forbidden to use the lead-acid battery or lithium battery pack of 60A or above.
  • 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 a 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.
  • The battery pack that can start the car can basically meet the power supply requirements of this circuit.
  • The following battery packs can be used as working power:
  • 1. 12V car starter power supply
  • 2. Model 3S high rate battery pack
  • 3. 3 string high rate lithium battery pack
  • 4. Hitachi 40900 3-string battery pack
  • 5. 12V 20A and above lead-acid battery with good performance
  • Switch function: press switch for 1.5 seconds to turn on (green light flash, output low power spot welding pulse every 3 seconds), press switch for 1.5 seconds (blue light flash, output medium power spot welding pulse every 3 seconds), press switch 1.5 Seconds (red light flash, high power spot welding pulse output every 3 seconds) Press the switch for 1.5 seconds to shut down.
