5Pcs Lighter Solder Wire | Lead-free, high-activity rosin core | For welding stainless steel, aluminium and copper | Low melting point—can be melted using a lighter | 20g/50g/100g

Say goodbye to soldering irons – metal soldering made easy with just a lighter NYOCAN has launched high-purity lead-free solder wire featuring a built-in composite rosin flux core (FLUX 2.2%). With an extremely low melting point, it can be melted using a standard lighter, eliminating the need for professional equipment such as soldering irons or torches. Suitable for rapid soldering of various metal materials such as stainless steel, aluminium, copper, nickel strips, lithium battery contacts, watches and instruments, and model DIY projects. The solder joints are bright, secure and resistant to tip formation. Key Selling Points 🔥 Can be melted with a lighter Extremely low melting point; the solder wire can be easily melted using the flame of a standard lighter No need for an electric soldering iron, soldering station or high-temperature soldering torch Convenient for outdoor, domestic and emergency soldering on the go ⚡ Highly reactive rosin flux core Contains 2.2% FLUX composite rosin flux Rapidly removes oxidation, excellent flowability, faster soldering speed Forms a protective film after soldering to prevent bridging and tip splitting 🧲 Universal multi-metal soldering Suitable materials: stainless steel, aluminium, copper, nickel strip, galvanised parts, nickel-plated items, iron, watches and instruments Particularly suitable for: lithium battery contacts, kitchenware, tinware, model-making and DIY 🛡️ Lead-free and eco-friendly + Strong and durable High-purity lead-free formula for stronger solder joints Bright, smooth solder joints that resist detachment Low corrosion, causing no damage to the base material Product Specifications (Table Format) Specification: Parameter Brand: NYOCAN Product Name: Lighter Solder Wire Wire Diameter: 0.8mm / 1.0mm Weight: 20g, 50g – 0.8mm / 100g – 1.0mm (Optional) Flux Content: 2.2% Suitable Heat Sources: Lighters, windproof lighters, low-temperature soldering irons Suitable Materials: Stainless steel, aluminium, copper, nickel strips, galvanised steel, nickel-plated steel, iron Environmental Standards: Lead-free, high purity Applications ✅ Repairing stainless steel kitchenware ✅ Soldering nickel strips/copper strips for lithium batteries ✅ Repairing galvanised parts and galvanised cast iron components ✅ Soldering aluminium to aluminium and copper to aluminium ✅ Watchmaking, instrument repair and model-making DIY ✅ Repairing electrical contacts and tinware Instructions for Use Clean the surface of the metal to be soldered (remove grease/oxidation) Heat the soldering area using a standard lighter or a windproof lighter Touch the solder wire to the heated area; it will melt and flow automatically Allow the solder to cool naturally to form a shiny joint No additional flux required; a rosin core is built-in 📌 Tip: We recommend using a windproof lighter for a more stable heat source
