Spot Welder, Portable DIY Integrated Welding Soldering Machine 18650 Battery Spot Welder Kit Six Gears Adjustable with A Charging Cable
  • After receiving the product, please charge it fully before using it to get the best results. This machine can weld 0.1-0.15mm nickel steel sheet and 0.1 pure nickel sheet. It is not to weld pure copper materials with strong conductivity.
  • This machine is equipped with 3.7V, 5.5AH lithium battery. After the single-chip microcomputer detects that the soldering pen touches the nickel sheet, it controls the "MOS" to turn on. Since the resistance of the soldering pen contacting the nickel sheet is much greater than that of other parts of the loop, most of the energy is concentrated here. The way of heating, the nickel sheet is melted, and the nickel sheet is welded to the battery.
  • When the product is not used for a long time, the battery power should not be kept too low or too high. If the power consumption is too low, the machine will not work and the charging light will not turn on. When this happens, please charge it, and it will recover after tens of minutes.
  • Current, voltage, and materials can affect the spot welding effect. Not all materials can get a good spot welding effect. What can now be adjusted is the spot welding time and contact strength. It is recommended to practice hands with iron cans first, and then solder the battery after getting familiar with the welding machine.
  • The product is equipped with a charging cable and no charger head. Please use a charging head with a fixed 5V output for charging. Do not use a fast charging head, otherwise the battery may be damaged.
