1. Material: plastic, metal aluminum alloy
2. There is a spring in the plastic handle of the manual solder suction device, which adopts a pull-back design to instantly enhance the suction power.
3. Adopt aluminum alloy anti-slip handle, stable operation and comfortable grip
4. The suction head is made of heat-resistant material and is suitable for high-temperature working environments.
5. Detachable design, easy to assemble, and the desoldering gun is easy to clean
6. Mainly used to remove tin solder when disassembling electronic components on circuit boards.
7. Dimensions: Total length approximately 19 cm, diameter 2 cm

Instructions:
1. Make sure the piston of the suction cup is well sealed. Before turning on the power, block the hole of the soldering head with your fingers and press the button of the soldering head. If the piston does not easily pop into place, it means the sealing is good.
2. The aperture soldering tips come in different sizes, choose the appropriate specification.
3. The tin suction cup head is worn and should be replaced with a new one.
4. The solder paste is dipped in a little rosin before contacting the solder to improve the fluidity of the solder.
5. The head contact pad is slightly longer. When the solder melts, take the solder pin as the center, then extend your hand clockwise to draw a circle, and then press the solder suction button
