60/40 Rosin Core Solder Wire, 0.6mm and 1.5mm Tin Lead Rosin Core Solder for Stained Glass, Electronics, Gauge wires, Jewelry, Electric Toys and Models,(0.6mm and 1.5mm/ 50g)

Not much to say about Rozen core solder. It works good requires low, heat to melt.

Having 0.6mm and 1mm allows for way more control and variable application. Solder works perfectly and all bonds have been solid with no issues. Highly recommend.

Solder is solder what else is there to know

It’s nice to have 2 sizes of solder to work with, but they didn’t put much on the spools. I already used some of the smaller size while I was replacing wire terminals in a battery charger, and it works well ... it’s easy to use, and it made a nice, tight connection.

The product is a nice soldering iron and looks like the picture. The instructions were kind of vague on everything, I took a picture to zoom in to be able to read them, especially to change from Celsius to Fahrenheit so I'm simply going with the Celsius setting.
