DIY Portable Mini Spot Welder Machine Various Welding Power Supply

DIY Portable Mini Spot Welder Machine Various Welding Power Supply Description

Feature:
A Wide Selection of Welding Power Supply: Lithium battery power supply or 12V car battery.
The controller is controlled by a single-chip microcomputer, and the output pulse is accurate to ensure the welding quality.
With an LCD display screen, can display welding parameters.
The welding pen and the input line are connected by U-shaped cold-pressed terminals, which are convenient for disassembly and replacement.
Using automatic touch welding mode, while retaining the manual trigger interface, you can choose according to your own use.
The power 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 fastest MOS tube can be hit with 20nS. The switch is fast 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 0.12mm.
A 25V10000uF high-frequency low-resistance capacitor is added to the power input for energy compensation, which increases welding stability.

Note:
Spot Welding Machine Set only, other accessories demo in the picture is not included.
Battery Selection:
1: 12V car battery from 25 to 40ah, requires good performance and small internal resistance.
