Agoal 18650 battery portable spot welding machine Mini DIY spot welding machine Various welding power sources with 2 power cords and LCD display

Package Included:
1 controller
2 x soldering pen
2Pcs x power input line (red and blue)
1 pair x U-shaped cold-pressed terminals (used to connect to the input power supply)
1 x black plug (when you select manual mode, an external trigger switch is required to connect the black plug.)

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 tube, undisassembled MOS tube.
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 0.15mm nickel-plated steel strip.
12. A 25V10000uF high-frequency low-resistance capacitor is added to the power input terminal to compensate for energy, thereby improving the welding stability.

Instructions for use:
1: Power connection
The controller comes with a 20cm long 10AWG input cable. A U-shaped terminal is crimped on one end, and the other end is unprocessed. Connect the crimped U-shaped terminal to the control power input terminal, and the other end will be processed according to its own power supply. Do not connect the negative pole incorrectly.

2: Open and close
There is a power switch under the control panel. After pressing, wait 3 seconds. After the buzzer falls, the LCD lights up and the startup is complete. Press the power switch again to turn it off.

3: Screen description and parameter adjustment.
Welding energy: 01-99 (adjustable by up and down keys)
Input: display the input power supply voltage
Welding method: manual/automatic (adjust through the "square label" button.)

4: Welding
Keep the solder pins clean. If the welding needle is polished into a round head, the welding effect can be improved. There are manual and automatic methods.
