1. enameled aluminum wire must be stripped. The paint stripping method can be mechanical (paint stripper, paint scraping) and chemical (paint stripping water, paint stripping powder). It is recommended to use chemical stripping and chemical stripping. After that, the solder joints must be fully rinsed; try not to remove the paint by mechanical methods to prevent the aluminum wire from scratching, causing burrs, and weakening the toughness; do not use high-temperature tin hot paint. 2. When connecting the enameled aluminum wire to the lead, the aluminum wire should be wound on the outside of the copper lead in a small arc, which can reduce the phenomenon of false welding and improve the welding strength. 3. Different tin should use different welding temperature: our special aluminum tin bar, the welding temperature is 330 degrees; the ordinary lead-free tin bar, the welding temperature is about 285 degrees; the lead tin, the welding temperature is 265 degrees. Because aluminum has a relatively low melting point, it is easy to melt into the tin pot. Therefore, our company recommends that when welding smaller diameter aluminum enameled wires (under 0.4mm), the temperature should be controlled within 300°C to reduce the melting speed of the aluminum wire and prevent the aluminum wire from becoming brittle. Do not use high temperature welding. 4. Due to the instability of aluminum, it is recommended to remove the paint and solder immediately. Do not expose the painted aluminum enameled wire ends to the air for a long time to prevent oxidation and facilitate welding. Generally speaking, welding must be carried out within 5 hours after the paint is removed. , If there is no welding, it needs to be cut and peeled. 5. The manufacturer can set the paint stripping length according to the welding length, that is, how long the welding takes to strip the paint. Do not expose the aluminum to the air to bury the hidden dangers of the solder joints. 6. When dip soldering, gently shake 2-3 times in the tin pot to avoid air bubbles. The precautions for Rectangular Enameled Aluminum Wire are the same, after all, they are the same kind of enameled wire https://www.xdmagnetwire.com/
