100% brand new and high quality
feature:
1. Wide selection of welding power supply: lithium battery power supply or 12V car battery.
2. The controller is controlled by a single-chip microcomputer, and the output pulse is accurate to ensure the welding quality.
3. With LCD display, welding parameters can be displayed.
4. The soldering pen and the input wire are connected through U-shaped cold-pressed terminals, which is easy to disassemble and replace.
5. Use automatic butt welding mode, while retaining the manual trigger interface, you can choose according to your own use.
6. The power board uses 2 strands of bronze to increase the overcurrent capacity.
7. Use 5 300A MOS tubes, non-disassembly MOS tubes.
8. 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.
9. The MOS driver design adds a transient diode to protect the MOS and prevent the tube from exploding.
10. Use 10AWG multifilament soft wire for soldering pen wire and input wire to increase the overcurrent capability.
11. The controller is mainly used for welding 0.1mm to 0.12mm nickel strips.
12. A 25V10000uF high-frequency low-resistance capacitor is added to the power input terminal for energy compensation, thereby improving welding stability.
Battery description:
According to actual tests, welding nickel strips with a thickness of 0.1 to 0.12 mm require 120 to 180 A of operating current. If the battery cannot output current within this range, welding will fail.
Recommended battery capacity:
1: 12V car battery from 25 to 40ahah, needs good performance and small internal resistance
2: 4000 to 6000mAh 45C to 60C 3S aircraft model lithium battery
3:30 to 35ahah 12V capacity lithium battery pack
