Solder Wire for Electronics Repair

This 63/37 tin-lead solder wire is designed for circuit board work and household appliance maintenance. The 0.8mm diameter suits both beginners and experienced users who need reliable joints on radios, televisions, refrigerators and air conditioning units.

Rosin Core with 1.8% Flux

The wire contains a no-wash rosin core at 1.8% flux content, removing the need for separate flux application and cleaning steps. Supplied on a spool inside a box, it stays protected from oxidation and feeds cleanly during hand soldering tasks.

50g Spool for Bench Use

At 50g the spool provides enough material for multiple repair sessions while remaining light enough for portable toolkits. The low melting point and good fluidity speed up joints, though the lead content means it is unsuitable for lead-free regulatory environments or potable water plumbing.

Questions about this item

Will the rosin flux core run out before the 50 g spool is finished?

The wire contains 1.8% flux uniformly distributed, so the core lasts exactly as long as the solder itself.

What property limits continuous soldering sessions with this alloy?

The 63/37 tin-lead composition melts at a single eutectic temperature, preventing the pasty range that slows work on other alloys.

Does the 0.8 mm diameter generate noticeable fumes during all-day use?

Lead content is 37%, so standard ventilation is required; the low melting point reduces overheating and excess smoke.
