5300mAh Mini Spot Welder 6 Gears Adjustable Portable Handheld Spot Welding Machine Fast Charge Lithium Battery with Pen This spots-welding machine is a high-power output design with 6 gears of output power adjustable, easy to adjust according to your welding requirements for a more accurate welding process. This product can be widely used in spots welding cylindrical lithium batteries, nickel metal hydride batteries, and nickel-cadmium batteries, such as 18650/26650/32650, etc. It supports welding 0.1-0.15mm nickel-plated sheets with solid and beautiful welding spots. Features: Working Principle: The welding process is based on the principle of high current and high temperature, rapidly melting part of the nickel sheet, and cooling.6 Gears of Power Adjustable: easy to adjust according to your welding demands, and the welding process is more accurate. A short click of the gear button adds a gear, power on the memory of the last gear, the six-speed cycle.Nickel-Plated Sheets: It supports soldered 0.1-0.15mm nickel-plated sheets with solid and beautiful welding spots. And built-in a 50C discharge high-rate lithium battery, which is fully charged for welding hundreds of welding joints.Recommended Working Power Source: This product can be widely used on spots welding cylindrical lithium batteries, nickel metal hydride batteries, and nickel-cadmium batteries, such as 18650/26650/32650, etc.Cellphone Battery Welding: Support welding cellphone battery, support welding mainstream cellphone battery.Faster Charging Speed: It supports welding hundreds of solder joints. It comes with a charging management control module, through the cellphone charging head, charging can be (5V, output current of at least 1A), free USB charging cable. To prevents charging accidents, charging when the welding function is not available.Breathing Light Reminder: When charged, the power lamp is kept on in the form of a breathing light reminder, and the full light is kept on after fully charged.Premium Welding Pen: 400mm in length, the 10AWG wire consists of multiple strands of high-temperature wire with high torsional resistance and more sensitive operation. Thick pure copper welding pen design, with alumina copper spots welding needles to ensure high current passing capacity and durability. The cold pressing process can make large contact areas with pure copper joints to reduce internal resistance.
