DIY Portable Crystal Valve Mini Welding Machine 18650 Lithium Cell Welding Machine Controller

Features:
Wide selection of welding power supply: lithium cell energy supply or 12V auto cell.
The controller is controlled by a single chip microcomputer, and the output pulse is accurate to ensure the welding quality.
With LCD display screen, can display welding parameters.
The welding pen and the input line are connected by U-shaped cold-pressed terminals, which is convenient for disassembly and replacement.
Using automatic welding mode, while retaining the manual trigger interface.
The energy board uses 2 Gusi copper to increase the overcurrent capacity.
Using 5 300A MOS tubes, non-disassembled MOS tubes.
The MOS tube driver adopts the imported special chip driver.
The most quick MOS tube can be hit with 20nS.
The switch is quick to prevent the explosion of the tube and the non-triode push-pull drive.
The MOS drive design adds a transient diode to protect the MOS and prevent the explosion of the tube.
10AWG multi-filament flexible wire is used for the welding pen line and the input line to increase the overcurrent capacity.
The controller is mainly for welding nickel-plated steel strips from 0.1mm to 0.15mm.
A 25V10000uF high-frequency low-resistance capacitor is added to the energy input for energy compensation, which increases welding stability.
