This spots-welding machine is a high-power output design with 80 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(0.2mm under full battery condition) nickel-plated sheets, stainless iron sheets or stainless steel 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. High Current: The design current is about 800A max, it supports welding 0.1-0.15mm(0.2mm under full battery condition) nickel sheets, stainless iron sheets or stainless steel sheets, with solid and beautiful welding spots. 80 Gears Adjustable: Dual pulse output, high power output design, 80 gears of output power adjustable, more accurate welding, suitable for continuously welding thousands of points on nickel/nickel-plate sheet. Digital Display: With the OLED color display real-time gear display function. Support system mode display, remaining power display, preheat display, time delay display, welding progress bar gear display. Two Modes Design: Dual modes selectable, supports automatic and manual mode switching by your needs. Mobilephone Battery Welding: support for welding all kinds of common to nickel cellphone batteries, coupled with the characteristics of portable, more convenient to go out to repairs cell phones. 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. Premium Welding Pen: The wire is consists of multiple strands of high-temperature wire with high torsional resistance and more sensitive operation. Quality Solder-Pin: Thick pure copper welding pen design, with alumina copper spots welding pins to ensure high current passing capacity and durability. Cold-pressing Technology: The cold pressing process can make large areas with pure copper joints to reduce internal resistance.
