0.4mm Heat Resistant Welding Wire (Green, 50m)

This 0.4mm heat-resistant welding wire comes in a 50m green spool designed for precision electronics work. Featuring silver-plated copper strands with PFA insulation, it is ideal for makers, technicians, and students working on fine soldering tasks.

Silver-plated copper core

The wire uses silver-plated copper strands to provide dependable electrical conductivity for delicate soldering jobs.

Heat-resistant PFA insulation

Durable PFA insulation protects the conductor and withstands high temperatures during component soldering and circuit rework.

Ultra-thin 0.4mm profile

The slim 0.4mm outer diameter allows for neat routing in dense electronics and compact project enclosures.

PCB repair and prototyping

The generous 50m length delivers ample material for point-to-point wiring, track bridging, and detailed PCB repair work.
