Use and maintenance of welding nozzle

When using the new welding nozzle, set the temperature to 250-280 ℃ to apply tin protection to the nozzle.

Choose the appropriate nozzle size based on the size of the solder joint.

To prevent oxidation of the soldering nozzle, a fresh layer of solder should be applied before placing it back on the iron frame.

The cleaning sponge should not contain too much water, which can achieve good cleaning effect on the welding nozzle and avoid rapid cooling of the welding nozzle; Using a non moist cleaning sponge can damage the solder nozzle and prevent soldering.

Improper use of the welding nozzle. After oxidation, do not clean the surface coating by grinding. Use metal wire or resurrection paste to clean the welding nozzle at low temperature (250-280 ℃).

Do not apply gravity to the welding nozzle during welding and avoid soldering at the same location.

Try to use low-temperature welding, generally controlling the welding temperature between 320-380 ℃. If high temperature is required for welding, please analyze whether the selection of welding station and welding nozzle matches.
