DC 12V 5MOS Spot Welding DIY Portable Battery Energy Storage Spot Motherboard 5 Gear Welding Machine 100-150A Machine Accessories

 

Description：

This spot welder circuit board can be used to weld 18650 / 26650 / 32650 lithium batteries. Advantages: portable, stable, reliable and durable. Low cost, own car start battery, or high-power battery pack, can be connected to use! Save production costs!

The battery with large discharge current will directly affect the welding effect. The following batteries are recommended:

36-45ah lead-acid battery with good performance and low internal resistance (internal resistance less than 10 milliohm, discharge current greater than 100 a), such as new car starting battery!

About 4000mAh 35c-8000mah 30C 3S aviation model lithium battery pack

18650 battery pack with 30-35ah capacity.

 

Function Keys:

1, for switching machine,

2 for shifting gear!

Turn on the power, the default is the first gear. Press the button for 2 seconds to release,

When the gear is increased by one gear, the buzzer rings and the LED flashes

For example: in the third gear, the buzzer rings three times and the LED flashes three times

There are 5 gears in total. The spot welding strength is gradually strengthened from the 1st to 5th gear, and the 5th gear is the strongest!

After the 5th gear, press and hold the key again. It will turn off. If you press the key for a long time, it will turn on. At the same time, the gear will return to the first gear

 

Note：

Users need to provide 12V battery power supply, welding current is about 100A ~ 200A, for the common 0.1mm ~ 0.15mm nickel plate welding is easy. Please make sure that your battery can have a current greater than 100A, otherwise it will not be able to weld!

Power supply voltage: 11.5v-14.8v

Working current: 100-200a (optimal current: 150A, discharge below 100A, will not work)

 

Power Requirements:

Spot welding is based on the principle of high current local rapid heating and cooling, which requires sufficient current supply. Generally, the welding current of 0.1-0.15 nickel plate is about 90-150a, so the working power supply of circuit board must be greater than or equal to 150A

The following battery pack can be used as working power supply

12V automobile starting power supply, aircraft model 3S high rate battery pack, three series high rate lithium battery pack, Hitachi 40900 3 series battery pack, 12V 20A lead-acid battery with good performance.
