With the HeiTools premium silver solder (Sn95.5Ag3.8Cu0.7), you leave nothing to chance when assembling cable and board repair. This specially alloyed soft solder has been developed to meet the highest demands on conductivity, workmanship and durability. Why 3.8% silver content is crucial Conventional solder can cause signal loss in sensitive audio components. Our HeiTools silver solder contains 3.8% pure silver (Ag). This high percentage guarantees excellent conductivity and ensures that your speaker cables, RCA plugs and tube amplifiers transmit the audio signal absolutely pure and unadulterated. Gentle processing thanks to 217 °C melting point. Especially when soldering expensive audio components (eg on crossovers) an exact temperature control is important. The HeiTools silver solder melts at a precise 217°C. This allows for fast and material-friendly soldering without damaging plugs or boards due to excessive heat. The optimal soldering iron temperature is 370-380°C. No-Clean flux (ISO-Core RA) - soldering like the professionals The 1 mm thick solder wire is filled with 2.5% halogen-containing activated rosin flux (ISO 9454-1, ROM1). This means for you: the solder flows extremely clean and optimally wets the surfaces. The special feature: the bright, solid residues do not cause any corrosion. They can remain on the solder point - the elaborate washing or cleaning after soldering is completely eliminated. Advantages at a glance: High-end alloy: Sn95.5Ag3.8Cu0.7 for lossless signal transmission in the HiFi and audio range. 100% made in Germany: manufactured by a renowned traditional company for the highest industry standards. HEALTH \u0026amp; ENVIRONMENT: Completely lead free and strictly compliant with RoHS Directive (2011\/65\/EU). Continuous temperature resistant: safe connections up to 150°C. Choose your needs: Whether you are looking for the economical 100 g spool for permanent workshop use or the practical 1 meter cut for quick DIY repair (eg headphones or cable break) - with HeiTools you rely on uncompromising premium quality from Germany.\u003c\/p\u003e \u003ch3\u003eProduct Features\u003c\/h3\u003e \u003cul class=\"a\"\u003e \u003cli\u003e100G SPOOL FOR PROFESSIONAL USE: This generous 100-gram roll on the practical spool is the ideal solution for workshops, cable factories, and ambitious home theater builders.
