Kester 44 Rosin Core Solder 60/40

Kester 44 Rosin Core Solder is a 60 percent tin and 40 percent lead alloy on a 16 ounce spool. The 0.062 inch diameter wire suits through-hole components and general wiring tasks. Electronics hobbyists and repair technicians use it for reliable joints on circuit boards. The rosin flux core cleans oxidation during melting.

Thermals noise and power draw

Soldering iron tip temperature controls the melt rate and fume volume. A temperature-controlled station limits thermal stress on components. Rosin flux produces visible smoke so ventilation or a fume extractor is advised. Power draw depends only on the iron wattage selected by the user.

Questions about this item

How do I feed the .062-inch diameter solder from the 1 lb spool into my soldering iron without it tangling?

Mount the 16 oz spool on a holder that lets it unwind freely, then pull the 60/40 rosin-core wire straight to the iron tip — forcing a bend near the spool causes kinks that jam the feed.

When will the rosin flux core in this 60/40 alloy stop cleaning effectively and need fresh solder?

The 44 rosin formulation remains active until the core is consumed; replace the spool once the grey 60% tin / 40% lead wire runs out, because the flux cannot be replenished separately.
