Rosin Core Soldering Tin Wire – 0.8/1.0mm Electrical Welding, 20–100g

Rosin Core Soldering Tin Wire – 0.8/1.0mm Electrical Welding

Clean joints every time. This rosin core solder wire flows smoothly and wets joints evenly — the built-in flux core cleans oxidation as you solder for strong, shiny connections without a separate flux pen or paste.

Why You'll Love It

• Rosin flux core — built-in flux cleans and protects the joint simultaneously
• 0.8mm or 1.0mm diameter — finer 0.8mm for PCB work, 1.0mm for general soldering
• Excellent flow — melts at low iron temperature and wets joints cleanly
• Low-spatter formula — minimal residue for clean, professional-looking joints
• 20g to 100g options — choose the amount that matches your project

Perfect For

PCB repair, electronics assembly, wire joining, jewelry, and any precision or general electrical soldering task.
