Small spot welding machine for 0.1-0.2 millimeter nickel welding machine digital screen spot welding for 18650 battery spot welding board

This spot welding machine is a high-power output design with a more precise welding process. Equipped with a digital display, it can clearly show the welding current, pulse time, pulse interval, continuous spot weld times, and other parameters, allowing you to read at a glance. The three parameters for preheating time, pulse interval, and pulse rate can be adjusted. You can set the screen brightness, automatic shutdown times, and other options, including using the log to display the number of factory departures. It can weld nickel-plated steel sheets with a diameter of 0.25 mm and pure nickel sheets with a diameter of 0.15 mm after full charge. The battery can remain in standby mode for a long time without use. Features: Working principle: controls high-rate lithium batteries through a program in the integrated microcontroller, outputs pulse energy accurately to generate high temperatures in a very short time. After rapid cooling, the nickel-coated layer and the battery are combined to complete the welding process. Digital display: equipped with a digital screen, it can clearly display welding current, pulse time, pulse interval, continuous spot weld times, and other parameters, easily readable at a glance. The backlight brightness can be adjusted from 5-100% according to the environment. Adjustable parameters: the three parameters for preheating time, pulse interval, and pulse rate can be adjusted to cover a wide range of welding conditions, from thin aluminum sheets for mobile phone battery joints to 0. Capable of meeting the thickness of 25 mm sheets and many functional requirements of users on the main interface. You can adjust screen brightness, automatic shutdown time, and other options, including using the log to display the number of factory departures. The battery can stay in standby mode for a long time without use. Multi-functional design: rechargeable, fast charging, built-in ammeter, low power standby, with silent mode. Strong welding capacity: the spot welder has two high-capacity built-in lithium batteries, and the single-chip CNC outputs a powerful pulse current for spot welding. It can weld nickel-plated steel sheets with a diameter of 0.25 mm and pure nickel sheets with a diameter of 0.15 mm when fully charged. The welding process is more precise, and the weld spots are stronger and more beautiful. Multiple protections: overcurrent protection, short circuit protection, low battery protection, over-temperature protection, over-temperature alarm, with automatic shutdown function. Excellent welding pen: diameter 8 mm, length 400 mm, 8 AWG wire made of multiple high-temperature resistant strands with high torsion resistance and more sensitive operation. Thick gold-plated interfaces with copper spot welding needles made of alumina to ensure high current passing capacity and durability.
