12V Battery Spot Welding Machine PCB DHJ6633 DIY Set Circuit DATE-1 Board F1B3

Description

Description
Description:
l It is portable, stable and reliable
l Users need to supply 12V battery power, welding current is about 90A ~ 150A
l Spot welding is welded by the principle of rapid local heating and cooling with high current. It requires sufficient current supply. Generally, the current of 0.1-0.15 nickel-plated sheet welding is about 90-150A, so the working power of the circuit board must be greater than or equal to 150A
Battery recommendation:
20-45ah start-up lead-acid battery with good performance and small internal resistance
3.5-5.5ah 3S model airplane lithium battery pack around 45C
30-35ah capacity 18650 battery pack
Specifications:
l Switch Function: press the switch for 1.5 seconds to switch (green light: low power, yellow light: medium power, red light: high power) System Voltage: 12V-14.6V
l Working Current: 90-150A
l Battery Recommendations: 20-45ah performance good start-up lead-acid battery with low internal resistance; 3.5-5.5ah 3S model airplane lithium battery pack above 45C; high-rate lithium battery pack, etc. (The battery pack that can start the car can basically meet this circuit Power demand)
Package Include:
l 1 Set Circuit Board
