ISOLDER MIX PACK is an innovative and efficient solution for fast, reliable, and professional wire connections, combining soldering, insulation, and waterproof protection in a single step. The product ensures secure, weatherproof connections. Once heat is applied, the solder melts and flows evenly, while the outer sleeve shrinks to provide insulation and environmental protection. ISOLDER-4 features a shrinkage ratio of 2:1 and operates reliably within a wide temperature range of -55 degrees C to +125 degrees C, ensuring consistent performance under demanding conditions. The minimum shrink temperature is 80 degrees C, with the solder beginning to melt at 115 degrees C and fully melting at 150 degrees C, guaranteeing a strong and stable electrical connection. The set consists of 70 pieces, covering a wide range of conductor cross-sections: 5 pcs: 0.25 – 0.34 mm² 30 pcs: 0.50 – 1.00 mm² 30 pcs: 1.50 – 2.50 mm² 5 pcs: 4.00 – 6.00 mm²
