Tin Soldering Iron Tip Without Flux

Old soldering iron may have flux stick to it.

Tin soldering iron tip without flux. Always use clean fluxes. SMT Solder Wire is done as follows. Cardboard works in a pinch.

When using the iron keep a little solder on the tip when the iron is in the stand. If you dont have flux you can use solder which contains flux for light oxidation though this may feel like a waste of solder. Dont let it run dry.

Wait till the Solder melts. Never apply flux directly to a soldering iron tip. Ive successfully retinned several very bad irons.

Only apply flux to the surfaces of the connection to be soldered. Soldering irons do not need a diode to operate. These tips will make sure your soldering tip does not become oxidized and need to be re-tinned.

This prevents oxidation and corrosion. To do so you will need something other than flux to break down the oxides on the metal surface without which your surface may be damaged or not properly cleaned. If you must apply solder to the tip when making the connection vary the surfaces that the solder is applied to.

Same goes for the old soldering iron but in a different way. If the tip loses its tin you want a product called tinning salts or sal ammoniac to restore wettability then re-tin with your usual solder. If youve not had the tip long then a few pointers to keep in mind.
