Mini Spot Welder DIY Welding Machine 18650 Battery Various Welding Power Supply

Description

Product Description
Wide selection of welding power supply, lithium battery power supply or 12V car battery.The controller is controlled by single chip microcomputer, and the output pulse is accurate to ensure the welding quality.
The controller adopts automatic welding mode, while retaining the manual trigger interface, which can be selected according to their own use.The power board adopts 2-ounce copper laying to increase the overcurrent capacity.
The controller has LCD display screen, which can display welding parameters. U-shaped cold pressing terminal is used to connect the welding pen and the input line for easy removal and replacement.
Adopt 5 300A MOS tubes, non-detuning MOS tubes, with good consistency. MOS tube driven by imported special chip, the fastest can be 20nS can be hit MOS tube, switch quickly, prevent tube explosion.Non-triode push-pull drive.
MOS drive design adds a transient diode to protect MOS from tube explosion.The welding pen line and the input line are made of 10AWG multi-wire flexible wire to increase the overcurrent capacity. The controller is mainly for 0.1mm to 0.15mm nickel plated steel strip welding.A 25V10000uF high frequency low resistance capacitor is added to power input for energy compensation to improve welding stability.
