Alloys and Fluxes
Soldering alloys (soft soldering) in use are produced in the form of wire only for the D.I.Y. market.
There do exist two types of soldering wire:
1. soldering wire without flux
2. soldering wire with flux core
Flux is used to remove the oxide coat from surfaces to solder as well as to prevent its formation
while soldering. Fluxes are available in paste and liquid form. After soldering, remove paste and
liquid fluxes from parts with a brush or a rug. Resin fluxes (rosin) should not be removed.

SOLDERING
•
The surfaces to be soldered must be clean, free from oil or dirt. Remove traces of oil or dirt by
using diluents or by cleaning.
•
Do not use household detergents since they often contain silicon. Oxide coal can be removed
either by using the corrosion method or mechanically with emery paper, file or scraping. If
corrosion is used, unskilled personnel should avoid using aggressive acids like hydrochloric acid,
sulphuric acid or nitric acid. For usual cleaning, the use of citric acid at 10% (hot or very hot) is
recommended. When cleaning is finished, do not touch surfaces to be soldered with fingers any
more.
•
Tips for soldering gun made of copper. When tips are heated a coat of oxide forms on their
surface. Remove oxide by rubbing on tips gently on a tip block. Wet clean tips with flux then tin
them.
•
The correct temperature is attained when tin deposited on tips forms a coat (film).The formation
of little clots means that the correct temperature has not been attained yet. If "tin pearls" are
formed, the tip is not perfectly clean.
•
After extensive use, tips may exhibit signs or corrosion caused by too frequent immersions in the
flux. Remove corrosion with a file or grind tips.
