12V DIY PCB Circuit Board Spot Welding Machine for 18650 26650 32650 Battery Spot Welder with Nickel

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. After several of product updates, it is now upgraded to automatically trigger welding and release the finger of the button.System voltage: 12V-14.6V ( 12V will stop)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. The battery capacity unit is: AH)Battery recommendation: 36-45ah Start-up lead-acid battery with good performance and small internal resistance (you must be 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. The battery pack that can start the car can basically meet the power supply needs of this circuitSwitch function: press the switch for 1.5 seconds to switch (blue light: low power, green light: medium power, red light: high power)Colour: blackMaterial: PC+metalPackage Contents:1 x Circuit board1 x 0.1 x 6mm nickel sheet 1 meter2 x wires2 x Output line with soldering pens3 sets x screws4 x copper earsOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
