12V Battery PCB Circuit Board Replacement Soldering Working Parts Supplies

Description:

High quality material made, durable.
Great for spot welder machine replacement parts.
Lightweight and small size, portable.
Users need to bring their own 12V battery for power supply, the welding current is about 90A~150A, and it is easy to weld the common 0.1mm~0.15mm nickel plated sheet.
System voltage: 12V-14.6V (below 12V will stop)

Specification:

Working current: 90-150A (lower than 90A, welding will not work, higher than 200A, it will damage the board, note that this refers to the short-circuit current, not the battery capacity.)
Battery recommendation:
36-45ah Start-up lead-acid battery with good performance and small internal resistance (you must be able to start a car, but not more than 45AH. If the battery is too large, the board will burn, if it is too small, it will not work. If it is a motorcycle If the performance of the battery is not good, you can connect 2 batteries in parallel to increase the current) 3.5-5.5ah 3S model airplane lithium battery pack above 45C, high-rate lithium battery pack, etc.
Switch function: press the switch for 1.5 seconds to switch (blue light: low power, green light: medium power, red light: high power)

Size Chart:

Circuit Board: 64x39mm / 2.52x1.54inch.
