Product features

High purity & low oxidation
Made of high-quality pure tin alloy with added flux. High-purity material reduces oxidation during soldering, improves tin flow speed, and leaves minimal residue.
Stable and reliable performance
Each roll is supplied with a sufficient amount, without wire tangles, and with evenly distributed internal rosin core filling for consistent welding. Provides excellent ductility, melting performance, electrical conductivity, and thermal conductivity.
Environmentally friendly & low smoke
Made of eco-friendly materials, no unpleasant odors, low spatter, and low smoke generation during use, safe and comfortable to operate.
Wide application
Easy to use and suitable for welding various metal materials, including galvanized parts, nickel-plated parts, iron, stainless steel, copper, aluminum, etc. Works well even at relatively low temperatures for daily repairs and small welding tasks.
Low-temperature solder wire – instructions for lighters
This flux-filled low-temperature solder wire is mainly used for repairing small metal components.

1. Preparation
Sand the welding area thoroughly to remove paint, oxide layers, and oil stains.
For thin wires, twist and fix the ends to prevent movement during welding.

2. Heating & welding
Use a windproof lighter and heat the joint evenly with the outer flame.
Gently touch the heated area with the solder wire; it will melt automatically above 360°C.
Allow the molten solder to flow evenly into the gap to ensure complete penetration.

3. Cooling & finishing
Remove the lighter once welding is complete and keep the workpiece steady for natural cooling.
For faster cooling, lightly wipe the surrounding area with a damp towel.
After cooling, no additional cleaning of residues is required.

Notes

Only for thin parts and small repairs; not intended as a replacement for electric welding equipment.
Avoid prolonged heating at the same spot to prevent burns or damage.
