12V Spot Welder Set DIY Portable Battery Spot Welding Storage Machine Circuit Board Welding Equipment For 18650 26650 32650

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 le than 10 millis, 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 Power requirements: Spot welding is welded by the principle of rapid local heating and cooling by high current, Need sufficient current supply, generally 0.1-0.15 nickel plated sheet welding current About 90-150A, so the working power of the circuit board must be greater than or equal to 150A. The following battery packs can be used as working power: 12V car starting power supply, 3S high-rate battery pack for model airplane, three-string high-rate lithium battery pack, 40900 3-string battery pack, lead-acid battery with good performance above 12V 20A. Calculation formula: capacity X discharge rate = load capacity Take 4000ma aeromodelling battery as an example, the discharge rate is 45C (4AX45C = 180A)

Instructions for use:

Function ons: 1, used to switch the machine, 2 used to switch gears! When the power is turned on, the default is the first gear. Pre the on for 2 seconds to release The gear is increased by one gear, and the sounds and the LED flashes corresponding to the number of gears. For example: the 3rd gear, the sounds three times, the LED flashes 3 times, a total of 5 gears. The spot welding intensity is gradually strengthened from the 1st gear to the 5th gear 5 is the strongest! After the 5th gear, pre and hold the on again. It will power off. In the off state, pre and hold the on to power on, and the gear will return to the first gear
