Welcome to our shop! These copper soldering tips are perfect for lower temperature soldering. They are not electroplated, making them easy to tin and diamagnetic. The super sharp needle-shaped points are ideal for crafted workmanship and soldering in tight spaces. They are also great for revising the tin bridge emerging from chip soldering. To keep these tips in good condition, avoid leaving your iron running for extended periods when not in use, as this can cause the tips to develop a black oxide cover. Instead, try to tin the tip as it heats. If you leave it on too long or run it too hot, the solder will burn off and the tip will go black again. These soldering tips are suitable for use with 936, 937, 938, 969, 8586, 852D soldering stations. The package includes 10pcs of the 900M-T-I model.
