The VALUE COLLECTION 21566 is a rosin core solder formulated with a 60/40 tin-to-lead alloy ratio, sold in a 3-unit pack. Rosin core solder is a standard consumable for electrical and electronics work, where the integrated rosin flux core cleans oxidation from joint surfaces during the soldering process and promotes strong, low-resistance connections. The 60/40 alloy melts at a relatively low temperature compared to higher-lead-content alternatives, making it practical for general-purpose electrical connections, circuit board work, and light-duty wiring tasks encountered in HVAC control wiring, electrical panel work, and similar trade applications.
This solder is suited for residential and light commercial electrical and electronics tasks where a traditional tin-lead rosin core formulation is appropriate. Common applications include soldering control board wiring connections, splicing low-voltage wiring, and general electrical repair work. The 3-pack quantity makes it a practical bench stock item for service technicians and shop settings handling frequent soldering tasks.
Designed as a general-purpose rosin core solder for standard electrical and electronics soldering applications across residential and light commercial trade work.
Soldering work on live electrical systems must be performed by a qualified electrician or licensed trade professional in accordance with applicable NEC requirements. Always de-energize and lock out circuits before making soldered connections in electrical panels or control systems. Use adequate ventilation when soldering, as rosin flux fumes require a well-ventilated work area. Allow solder joints to cool undisturbed before handling to ensure a solid, low-resistance connection.
