12V Spot Welder DIY Portable Spot Welding Storage Machine Circuit Board

Description:

This spot welding machine circuit board can be used to weld 26650/32650 and other lithium batteries.
Advantages: portable, stable and reliable, and durable. Low cost, you have your own car startup battery,
or high-power battery pack, you can use it after connecting it! Saving the production cost!

Added the smart spot welding program, withdrew the trigger switch, and used the program to automatically control the spot welding action. When the welding pen touches the nickel sheet, the spot welding pulse is automatically output! Do whatever you want! No need to press the switch! At the same time, the delay is abandoned. Spot welding mode! Everything is handed over to the program, free your hands, and really achieve the effect of just clicking when you think!

Upgrade from the original three gears to the current five gears. This can better adapt to different batteries, batteries with lower performance can also be spot welded, and also adapt to more convenient use scenarios, different nickel sheet thickness There can be more gear options!

The structure of the board has been optimized, and the circuit design is more reasonable!
Users need to bring their own 12V battery power supply, the welding current is about 90A~130A, more
than the common 0.1mm~0.12mm nickel plated welding welding edge. Please ensure that your battery
can have a current greater than 90A, otherwise it will not be soldered!

Specification:

• Can be welding 18650/26650/32650/ lipo battery, it is portable, stable and reliable
• System voltage: 12V-14.6V
• Working current: 90-150A

Suggested Battery:

• 30-45ah Lead-acid battery with good performance and small internal resistance
• 3.5-5.5ah 45C 3S aero model lithium battery pack
• 30-35ah capacity 18650 battery pack

This circuit with a 12V battery will become an energy storage spot welding machine for welding
nickel pieces such as lithium batteries and nickel-chromium batteries. According to different
configurations, the thickness can be about 0.1MM-0.15mm
If you are not sure about your battery, it’s better to extend the wire by around 1 meter with 2.52
or 42 wire, then it will reduce the risk of power tube burnt.
