--Single Chip Microcomputer: The controller adopts single chip microcomputer control, accurate output pulse.

--LCD display screen, can display welding parameters.

--This controller is mainly used for welding small battery repair power banks, power tools, model airplanes, etc.

--U-shaped Cold-pressed Terminals: The soldering pen and the input wire are connected by U-shaped cold-pressed terminals, which is convenient for disassembly and replacement.

--Size: about 10x5x2.8cm/3.94x1.97x1.10 inch.

Feature:

1. Welding Power: The welding power can be powered by lithium battery or 12V car battery. The controller is mainly for welding 0.1mm to 0.15mm nickel-plated steel strip, and the power input adds a 25V10000uF high-frequency low-resistance capacitor for energy compensation to increase stability.

2. Good Overcurrent Capacity: The power board uses 2 ounces of copper, and the soldering pen wire and the input wire use 10AWG multi-wire soft wire to increase the overcurrent capacity.

3. Automatic Welding Mode: The controller adopts automatic welding mode, while retaining the manual trigger interface, you can choose according to your own usage. Five 300A MOS tubes are driven by imported special chipss, and the MOS tubes can be used as fast as 20nS, which can switch quickly to prevent tube explosion.

Description:

Product name: Spot Welder Set

Material: metal

Input line length: about 20cm/7.87in

Length of welding pen: about 30cm/11.81in

Color: red, blue and black

Size: about 10x5x2.8cm/3.94x1.97x1.10 inch

Instructions for use:

1. Power connection: The controller comes with a 20cm long 10AWG input wire. One end has been crimped with a U-shaped terminal, and the other end has not been processed. Connect the crimped U-shaped terminal to the control power input terminal , and the other end is processed according to its own power supply. Do not connect the negative electrode wrong.

2. Switch on and off: There is a power switch under the control board. After pressing, wait for 3 seconds. After the buzzer drops, the LCD lights up and the boot is complete. Press the power switch again to shut down.

3. Screen description and parameter adjustment.

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