Mini Spot Welder Machine 18650 Battery Welding Power Supply Nickel Sheet DIY USA

Description

Feature:
-Wide choice 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, which ensures the welding quality.
-With LCD display, which can display welding parameters.
-The soldering pen and the input wire are connected by U-shaped cold-pressed terminals, which is easy to disassemble and replace.
-Use the automatic touch welding mode, while retaining the manual trigger interface, you can choose according to your own use.
-The power board uses 2 strands of bronze to increase the overcurrent capacity. Use 5 300A MOS tube, undisassembled MOS tube.
-MOS tube driver adopts imported special chip driver. The fastest MOS tube can reach 20nS. The switch is fast and can prevent the explosion of electronic tube and non-triode push-pull drivers.
-MOS driver design adds a transient diode to protect MOS and prevent lamp explosion.
-10AWG multifilament flexible wire is used for welding pen wire and input wire to increase the overcurrent capability.
-This controller is mainly used for welding 0.1mm to 0.12mm nickel-plated steel strip.
-A 25V 10000uF high-frequency low-resistance capacitor is added to the power input terminal for energy compensation, thereby improving welding stability.
Note:
Only the spot welder kit, does not include the demonstration of other accessories in the picture.
Battery selection:
1: 12V car battery (25-40ahah), requires good performance and low internal resistance
2: 4000 to 6000mAh 45C to 60C 3S model aircraft lithium battery
