We recommend triple filtered Butane, easily bought on amazon.

High quality clean butane will not clog your butane powered tools ensuring proper functionality and a long lasting product. Low quality butane is full of impurities which will eventually ruin and or at the very least clog your torches, lighters , or soldering irons.

When deciding between brands look for the least ppm (parts per million) of impurities.

Many metals oxidize with the oxygen in the air after a few seconds. This impairs the durability of the soldered joint. Flux exerts a cleaning effect and ensures a perfect soldered joint. The oxidation layer on metals dissolves in the flux and evaporates as soon as the flux has reached boiling point.

In industry, rosin is a flux used in soldering. The lead-tin solder commonly used in electronics has 1 to 2% rosin by weight as a flux core, helping the molten metal flow and making a better connection by reducing the refractory solid oxide layer formed at the surface back to metal. It is frequently seen as a burnt or clear residue around new soldering.

Our Iroda Soldering kits come with 60/40 Rosin Solder Core Ø 1.0mm.
