Spot Welder 12V 150A DIY Kit:
Specifications:
System Voltage: 11.5-14.6V
Working Current: About 150A
Suggested Battery:
12V (35AH-45AH) Start-up lead-acid battery with good performance and small internal resistance with discharge current greater than 100A
12V 30-35AH 18650 battery pack with good performance
The battery pack that can start the car can basically meet the power supply needs of this circuit
The transformer cannot replace the battery pack for power supply, and the wire cannot be extended or replaced with other wire diameters or materials.
Switch Functions:
When the power is turned on, the default is the first gear. Press the button for 2 seconds to release.
The gear is increased by one gear, and the buzzer sounds corresponding to the number of gears.
For example: the 3rd gear, the buzzer sounds three times and there is a total of 5 gears. The spot welding intensity is gradually strengthened from the 1st gear to the 5th gear
with the 5th being the strongest.
After the 5th gear, press and hold the button again. It will power off. In the off state, press and hold the button to power on, and the gear will return to the first gear.
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.
