1. When soldering the solder wire, the working temperature should be effectively controlled, so as to ensure that the solder wire has a good welding effect. When soldering the solder wire, it should be avoided to put the appropriate solder wire into the tin pot, connect it to the tin pot, turn the power switch over and adjust the working temperature to about 250 degrees Celsius, and use the solder wire to coat the red heating tube. The disposal of the tin ensures that the entire tin surface can completely cover the heating tube. When the solder wire is melted, the solder wire should be added appropriately to ensure that the temperature of the tin surface is maintained at a relatively appropriate value.

2. When the solder wire is in use, if there is solder wire left in the tin furnace, do not cut off the heating power supply of the tin furnace. At this time, the working temperature should be adjusted appropriately to avoid accelerating the oxidation reaction of the tin surface. Usually we can control the working temperature of 63/67 solder wire at about 250 degrees Celsius, 50/50 solder wire should be controlled at about 280 degrees Celsius, and 30/70 solder wire should be controlled at about 300 degrees Celsius. .

1. When investigating the working temperature of the tin furnace of the solder wire, you should not simply check the appearance of the tin furnace itself, which will cause a relatively large error. You should use a special thermometer to pierce the tin furnace for testing. Usually high temperature solder The working temperature of the wire should be controlled within 400-500 degrees Celsius. If the working temperature is not reached, there will be problems with continuous welding and solder joints not shining. Therefore, when using solder wire for welding, the working temperature should be strictly controlled, so as to ensure the welding quality of the solder wire.
