Soldering irons with solder included

Solder

— the main "consumable" for soldering, which is responsible for the direct connection of parts to each other. The molten solder adheres tightly to the parts, fills the gap between them and, solidifying, creates a strong connection. The composition and specialization of the solder can be different: there are solders from a low-melting alloy based on lead and/or tin for manual work with metals, from all kinds of oxides for soldering metals and non-metals, etc. Solder is available in various forms — thin wire, rods, pastes, powders, suspensions. Some formulations immediately include rosin, so working with them does not require the use of separate fluxes.
