Spot Welding Machine Accessories, Welding Pen Accessories, 12V Battery Spot Welding Machine, Circuit

Used for welding 18650\/26650\/32650 lithium batteries, advantages: portable, stable, reliable and durable.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-0.12mm nickel plated sheet. After several of product updates, it is now upgraded to automatically trigger welding and release the finger of the button.The battery pack that can start the car can basically meet the power supply needs of this circuitUse steps: Long press the switch for 1.5 seconds to adjust the power, the indicator light shows green, blue, and red respectively. Low, medium and high powerUsage: Welder control panel1: Negative welding pen output (The wire ears must be installed close to the top of the circuit board)2: Connect the positive electrode soldering pen and the positive electrode of the battery to the common terminal (Two wire ears must be connected to the back of the circuit board at the same time)3: Negative battery input (The wire ears must be installed close to the top of the circuit board)All the red wires are connected to the bottom of the circuit board.All the black wires are connected to the top of the circuit board.System voltage: 12V-14.6VBattery recommendation(Does not include battery): 20-45ah lead-acid battery with good performance and small internal resistance3.5-5.5ah 3S model airplane lithium battery pack around 45C30-35ah capacity 18650 battery packcolour:BlackMaterial:PCBPackage Contents:1 x Circuit board1 pack x accessoriesOnly 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.
