Description

DIY Mini Spot Welder Motherboard Three Gears w/ Indicator Automatic Trigger Kit
Product brief  introduction:
System voltage: 7.2V-14.6V
Operating current: about 150A
Trigger mode: automatic trigger
Users need to bring their own 7.2V-14.6V batteries for power supply, and the welding current is about 150A, which is easy for common welding of 0.1mm~0.15mm nickel-plated sheets.
Battery recommendation:
12V(35AH-80AH) start-up lead-acid battery with good performance and small internal resistance
Aeromodel lithium battery pack with good performance above 12V 4000MAH 45C
5-6 strings of 3000F farad capacitor banks, etc.
The battery pack that can start the car can basically meet the power supply requirements of this circuit
Transformers cannot replace battery packs for power supply, and wires cannot be extended or replaced with other wire diameters or materials.
Switch function: press the switch for 1.5 seconds to switch (blinking once, twice, and three times are the third power respectively, and then press to shut down again) and automatically shut down after idle for 10 minutes
Package includes:
1x Main circuit board
