Soldering is a means of becoming a member of two items of steel by melting a lower-melting-point steel alloy (solder) into the joint. A soldering iron is a device used to warmth the solder and the steel items to be joined.
Over time, the tip of the soldering iron can turn into soiled or oxidized, which might make it troublesome to solder successfully. Cleansing the soldering iron tip usually is due to this fact necessary to keep up its efficiency.
