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

This 0.4mm heat resistant welding wire is an ultra-thin connecting wire supplied on a 50-metre spool. Featuring durable PFA insulation and silver-plated copper strands, it is ideal for makers, technicians, and electronics hobbyists tackling delicate PCB rework and miniature circuit assemblies.

Ultra-thin 0.4mm outer diameter

With an ultra-thin 0.4mm profile, this wire easily routes through tight spaces on crowded circuit boards. It is well suited for precision jumper links, trace repairs, and compact electronic builds.

Silver-plated copper conductors

The internal core is constructed from stranded silver-plated copper for dependable electrical conductivity. The multi-strand composition provides flexibility during intricate soldering and rework tasks.

High-grade PFA insulation

The wire is wrapped in black PFA insulation to protect conductors from accidental shorts and physical wear. It delivers durable electrical isolation in demanding operating environments.

Broad operating temperature range

Rated for continuous operation between -60°C and 250°C, this wire withstands extreme heat and cold. It easily handles high-temperature soldering without melting or degrading the outer jacket.
