After using for a period of time, when your two solder pins become loose, they will slide out during operation and affect your use. We need to use a screwdriver to loosen the two screws so that the solder feet can slide in the chip and place them in the correct position. , And then tighten the screws to make sure it is firm and the connection here is clean. You can continue to use it normally.

Once the positioning is good, it can be grounded. This does solve many problems and improve your office efficiency. Click the button to release the current and perform spot welding.

The advantage of this is that you can use a larger battery to work. Therefore, when you use both hands to accurately connect the welding press, foot pedal and finish, it is more convenient for you to use.

  1. For the sake of safety. Before using the portable spot welder, you must carefully read the safety instructions and user guide that comes with the spot welder. Always follow the instructions provided by the manufacturer.
  2. When the electrode is transferring heat, please do not place it on flammable materials. If you place them, make sure they are in a cool state. Otherwise, it may cause an open flame and may cause large-scale damage.
  3. During the welding process, if the electrode arrangement is not correct, the electrode may be stuck. If the force is too low, it may stick. If the welding current is too high or the welding time is longer than the recommended time, it may cause welding spatter. Therefore, please check correctly before working and always follow the correct parameters.

4.If the heat is extreme, electrodes can get stuck too. So, remember to keep an eye on this as well!
