Review on Solder Wire Sn63 Pb37 with Rosin Core for Electrical Soldering 50g (0.8mm) by TAMINGTON: High-Quality Soldering Wire with Rosin Core by Marquez Hinshaw

Very good quality. Contains the main element lead. Do not chew, wash hands after preparation, avoid inhaling smoke. If you throw a tantrum and live in California, you may or may not get cancer at some point in your life. Not necessarily from this product, but driven to hysteria and living in California. By the way, this is a 0.8mm wire. For hand soldering, you can choose a wire with a diameter of 1.5 mm. (.031", .061 is easier)
