The reason why the soldering iron head of an automatic soldering machine becomes fragile:

1、 Reason for oxidation gap: During the use of the soldering iron head, the temperature can reach over 400 degrees. At high temperatures, the corrosion of the coating is extremely severe. If the coating thickness is insufficient or bubbles and carbonization occur inside, wear and tear during use may lead to perforation. Improvement method: Properly reducing the temperature of the soldering iron head can extend its service life, but considering the welding speed and quality, this method cannot be used. The improvement plan is as follows: selecting pure imported red copper, optimizing the electroplating process, enhancing the density of the coating, and improving the antioxidant ability.

2、 Reason for wear and deformation: Due to long-term use of soldering iron in high-temperature environments, the friction between the soldering iron head and the welding material causes the blade to become thin and curled. Improvement method: As the soldering iron is damaged during natural use, improvement from soldering iron maintenance has little effect. The manufacturer can only be required to change the material to enhance its wear resistance strength.

3、 Minor deformation cause: Natural wear and tear during use.
