Portable Transistor Mini Spot Welding Machine 18650 Battery Spot

1. Wide of welding sources: lithium battery supply or 12V car battery. 2. The controller is controlled by a single-chip microcomputer and the output is to the welding quality. 3. With LCD screen it can display welding parameters. 4. The welding pen and the input line are connected by U- cold-pressed terminal which is convenient for disassembly and replacement. 5. The automatic touch welding is adopted and the manual trigger interface is retained which can be according to your own usage. 6. The board adopts 2 copper wires to increase the overcurrent capability. 7. Using 5*300A MOS tube no need to dismantle the MOS tube. 8. The MOS tube driver adopts imported special chip driver. The fastest MOS tube can hit 20nS. Fast switching preventing tube burst non-triode push-pull drive. 9. The MOS drive design adds a transient diode to the MOS and prevent the tube from bursting. 10. 10AWG multi-filament flexible wire is used for soldering pen wire and input wire to increase the overcurrent capability. 11. The controller is mainly used for welding -plated steel strips from 0.1mm to 0.15mm. 12. 25V10000uF high-frequency low-resistance capacitor to the input for energy compensation and increase welding stability. size:10x6x3cm Material:Metal colour:red Package Contents: 1 * DC head 2 * Soldering pen line 1 * Spot Welder Only the above package content other products are not included.
