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

This 0.4mm heat resistant welding wire is an ultra-thin connecting wire designed for precise electronics assembly and rework. Supplied in a 50-metre red spool, it is ideal for makers, students, and technicians working on tight PCB wiring and prototyping tasks.

Ultra-thin 0.4mm outer diameter

The ultra-thin 0.4mm profile makes this wire easy to route through dense circuit board layouts. It allows for neat, unobtrusive point-to-point connections and fine jumper links.

Silver-plated copper core

Stranded silver-plated copper conductors provide reliable electrical conductivity and smooth solderability. The construction ensures dependable signal transfer during delicate prototyping work.

Durable PFA insulation

The wire features tough PFA insulation that withstands high working temperatures without melting back during soldering. It offers an operating temperature rating spanning from -60°C to 250°C.

Generous 50-metre spool

Supplied as a continuous 50m reel of red wire, this spool delivers ample length for electronics projects, circuit modifications, and benchtop prototyping.
