DIY Portable 12V Spot Welding PCB Circuit Board Kit

Description

This spot welder circuit board can be used to weld 18650/26650/32650/32700 and other lithium batteries. It is Portable, stable, reliable and durable. Power with your own car starter battery, or a high-power battery pack, just connect it and you can use it. Battery is not included. The welding current is about 90A~130A, and it is easy to weld the common 0.1mm~0.12mm nickel plated sheet. Please ensure that your battery can have a current greater than 90A, otherwise it will not be able to weld properly.

Specifications:

• Supply Voltage: 12-15 V
• Welding Current: 90-130 A
• Working Current: 90-150A
• Portable stable, reliable, and durable

It cab be powered using 2200mAh 3s LiPo Battery or Good 12V Lead Acid Battery (Car Battery). For LiPo battery with Max. Burst Discharge Rate of 60C, it can produce up to 132Amps. Below it the formula to calculate Amps with C Rating,

Calculation Formula: Capacity X discharge rate = load capacity

Eg: In 2200mA drone battery, the discharge rate is 60C (2.2AX60C = 132A)

Note: It is a DIY Kit, few components need to be soldered by yourself.

Batteries may rated both Continuous and burst discharge rates like 25C/60C, It is recommended to consider higher Amps/Discharge rate battery it the spot welding is used continuous.

Button Function and Modes:

• There 5 Different modes available with ON OFF, each mode has different power for spot welding different size of nickel strips or batteries.
• Press and Hold the button for 3 seconds to change the modes.
• The power will gradually increase from Mode 1 to Mode 5.
• Adjust the welding power based on your application and welding quality.
