DIY Portable 12V Battery Energy Storage Spot Welding Machine PCB Circuit Board Welding Equipment Spot Welding Machine Accessory
Foreword: Thank you for your attention. This product is a semi-finished circuit board. You need to have a certain electrical knowledge and hands-on ability. You also need to prepare some necessary tools such as pliers, screwdrivers, soldering irons, etc.
Note:Battery Not Include
Description:
The circuit board of this spot welder can be used for welding 18650/26650/32650 lithium batteries. Advantages: portable, stable, reliable and durable. Low cost, you have a car starter battery, or a high-power battery pack, you can connect it and use it! Save production costs!
Users need to bring their own 12V battery for power supply, the welding current is about 90A~130A, and it is easy to weld the common 0.1mm~0.12mm nickel plated sheet. Please make sure that your battery can have a current greater than 90A, otherwise you will not be able to weld!
Power supply voltage: 12V-15V
Working current: 90-150A (discharge below 90A, it will not work.)
A battery with a large discharge current will directly affect the welding effect. The following batteries are recommended:
20-45ah Lead-acid batteries with good performance and small internal resistance (internal resistance less than 10 milliohms, discharge current greater than 90A), such as a new car starter battery!
3.5-5.5ah 3S model airplane lithium battery pack around 45C
30-35ah capacity 18650 battery pack
