When we use
solder wire for welding, we should effectively control the temperature, so as to ensure that the solder wire has a better welding effect.
1. When using solder wire, if there is still solder wire left in the tin furnace, do not cut off the heating power supply of the tin melting furnace. At this time, the temperature should be properly controlled, and the set temperature should not be too high , to avoid accelerating the oxidation reaction of the tin surface. Generally, we can control the temperature of 63/67 solder wire at about 250 degrees Celsius, the temperature of 50/50 solder wire should be controlled at about 280 degrees Celsius, and the temperature of 30/70 solder wire should be controlled at about 300 degrees Celsius.
2. When soldering with solder wire, you should keep the appropriate solder wire in the tin pot, connect the power supply to the tin pot, turn on the power switch and adjust the temperature to about 250 degrees Celsius, and use the solder wire on the red heating tube Apply tin to ensure that the entire tin surface can completely cover the heating tube. When the solder wire is melting, the amount of solder wire should be added appropriately to ensure that the tin surface is at a relatively suitable temperature.
3. When we observe the temperature of the tin furnace of the solder wire, we should not simply observe the appearance of the tin furnace itself, which will only cause relatively large errors. We should use a special thermometer to insert into the tin furnace for testing. Generally, the working temperature of high-temperature solder wire should be controlled within 400-500 degrees Celsius. If the temperature is not reached, it will cause problems such as continuous welding and dull solder joints.
When using solder wire for welding, the temperature should be strictly controlled, so as to ensure the welding quality of the solder wire.
