Enameled Rectangular Copper Wire Welding

    1. enameled aluminum square wire must be stripped of paint. Two types of paint stripping methods (mechanical (paint stripper, paint scraping) and chemical (paint stripping water, paint stripping powder) can be used to remove paint. Chemical paint removal is recommended. After the paint is removed, the solder joints must be rinsed adequately; try not to use mechanical methods to remove the paint, avoid aluminum wire scratches, burrs, and weakened resistance; never use high-temperature tin hot paint.

      2. When connecting aluminum enameled wire and lead, the aluminum wire should be wound on the outside of the copper lead with a small arc, which can reduce the occurrence of false welding and improve the welding strength.

     3. Different soldering temperature should be used for different tin: our company's special aluminum tin bar, the soldering temperature is 330 degrees; the ordinary lead-free tin bar, the soldering temperature is about 285 degrees; the leaded tin, the soldering temperature is 265 degrees. Because aluminum has a relatively low melting point and is easily melted into the tin pot, our company recommends that when welding smaller diameter aluminum enameled wires (below 0.4mm), the temperature should be controlled within 300°C to reduce the melting speed of the aluminum wire and avoid aluminum. The thread becomes brittle. Never use high temperature soldering.

    1. Due to the instability of aluminum, it is recommended to remove the paint and solder immediately. Do not let the enameled rectangular copper wire thread after the paint be exposed to the air for too long to avoid oxidation, which is good for welding. Generally speaking, within 5 hours after the paint is removed It is necessary to weld, if there is no welding, it needs to be cut off and peeled off again.

      5. The manufacturer can determine the paint stripping length according to the welding length, that is, how long the welding is and how long to remove the paint. Do not expose the aluminum to the air, which will bury hidden dangers for the solder joints.

      6. ​​When dipping, shake gently in the tin pot 2-3 times to avoid bubbles.
