Multi-protections Spots Welding Machine Lithium Battery Welding Device Built-in Welding Ammeter with Charging Pal Function DIY Complete Kit for 0.25mm Nickel Plated Sheet and 0.15mm Pure Nickel Sheets

Features:
Working Principle: It controls the two high-rate lithium batteries through a program in the built-in microcontroller, and precisely outputs the pulsed energy to generate the high temperatures in a very short time. After quick cooling, the nickel-plated sheet and the battery are fused together to complete the welding process.
Digital Display: Equipped with a digital display, the welding current, pulse time, pulse interval, number of continuous spots welding times and other parameters can be clearly displayed, and you can read it at a glance. The backlight brightness of 5-100.0% can be adjusted depending on the environment.
Parameters adjustable: The three parameters of preheating time, pulse interval and pulse rate can be adjusted to cover a wide ranges of welding situations, from thin aluminum sheets of mobilephone battery lugs to 0.25mm thick sheets, and lots of users' functional requirements can be met at the main interface. You can adjust the screen brightness, automatic shutdown time and other options, including using the record to view the number of leave factory times. The battery can be kept at a standby voltage for a long time without being used.
Multifunctional Design: With rechargeable capability, fast charging, built-in welding ammeter, low power consumption standby, with silent mode.
Strong Welding Capacity: The spots welding machine has two built-in high-rate power lithium batteries, and the single-chip outputs a powerful pulse current for spots welding. It can firmly welds 0.25mm nickel-plated steel sheets and 0.15mm pure nickel sheets at full-charged. The welding process is more accurate and the welding spots are more solid and beautiful.
Multiple Protections: over-current protections, short-circuit protections, low battery protections, over-temperature protections, over-temperature alarms, and with automatic shutdown function.
Premium Welding Pen: 8 mm diameter, 400 mm length, 8AWG wire consists of multiple strands of high-temperature wire with high torsional resistance and more sensitive operation. Thick gold-plated interfaces with alumina copper spots welding needles to ensure high current passing capacity and durability
