What is the Harris 40R61 40/60 Leaded Rosin-Core Solder - 1/8 in (3.2 mm) - 1 lb Spool used for?

Solder is used for joining metal components at temperatures below 840°F (450°C) in plumbing, electronics, and light metal fabrication. Select the solder based on your application: lead-free is required for potable water plumbing; tin-lead solders are still used in electronics repair and non-potable applications where permitted by code.

Does the Harris 40R61 40/60 Leaded Rosin-Core Solder - 1/8 in (3.2 mm) - 1 lb Spool require separate flux?

A separate flux must be applied to clean joint surfaces before soldering with wire or bar solder. Harris Bridgit Flux or a similar non-corrosive paste flux is recommended for plumbing copper joints. Apply flux to all contact surfaces, assemble the joint, then heat the base metal and touch solder to the joint — the solder flows by capillary action into the flux-wetted gap. Remove flux residue after the joint cools.

What is the correct soldering technique for the Harris 40R61 40/60 Leaded Rosin-Core Solder - 1/8 in (3.2 mm) - 1 lb Spool?

Soldering technique for copper plumbing: clean pipe and fitting surfaces with sandpaper or steel wool until bright, apply paste flux, assemble the joint, and heat the fitting (not the solder) with a torch until solder flows freely when touched to the joint. Remove heat as soon as the solder flows — overheating burns the flux and can cause a dry joint or oxidized solder. Allow to cool for 30 seconds before wiping and moving the assembly.

What diameter and quantity is the Harris 40R61 40/60 Leaded Rosin-Core Solder - 1/8 in (3.2 mm) - 1 lb Spool available in?

The Harris 40R61 40/60 Leaded Rosin-Core Solder - 1/8 in (3.2 mm) - 1 lb Spool is available in 1/8 diameter. Wire solder diameter selection depends on the joint size: fine wire (.050–.062 in) suits electronics and tight plumbing fittings; medium wire (.093–.125 in) is the most versatile for general plumbing work; larger diameter wire suits large-bore fittings and faster deposition.

How should I store the Harris 40R61 40/60 Leaded Rosin-Core Solder - 1/8 in (3.2 mm) - 1 lb Spool?

Store solder in a cool, dry location away from moisture and chemical fumes. Lead-free solders containing silver (Sn-Ag, Sn-Ag-Cu) are more brittle than traditional tin-lead solders and should be handled with care to avoid cracking the wire on the spool. Flux-core solder should be stored away from extreme heat to prevent flux degradation inside the core.

40/60 leaded rosin core solder 1/8 in. x 1 ea. 1 lb. spool

Overview

40/60 tin-lead rosin core solder contains a 2.2% rosin core center. It is a popular choice for soldering electrical and electronic connections. Generally, rosin core solders are used for small connections, as there is a limited amount of flux available for protection of large surface areas. Heat sources include soldering guns, irons, and air-fuel torches. Lead bearing solders are not to be used in potable water system applications.
