Below, we give you some examples of poorly soldered joints:
▪
It the soldering tin is tear-shaped, the soldering coagulate was too cold.
▪
If the soldering tin is dull and slightly porous or crystalline, the parts were probably
moved during the cooling process.
▪
If too little soldering tin has been left in the joint, the soldering was too warm or the
soldering tin was not melted sufficiently.
▪
If the soldering tin is yellow or black, this means that too much soldering paste has
been used or that the inner core of the tin solder wire has become overheated during
soldering.
▪
You must avoid this above all in electronic circuits since most acid pastes are
corrosive and reduce the service life of electronic wiring.
3.2.1
Replacement of thesoldering tip
Pull out the mains plug!
▪
The tip and housing of the soldering gun are connected by means of a contact piece
so that the soldering gun can be comfortably repaired and changed. Wear and tear of
the tip after longer periods of use makes replacement necessary at regular intervals.
▪
To replace the soldering tip:
a. Unscrew the 2 fixing screws, which hold the tip and the housing together, and
remove the old tip.
b. Put in the new tip (1) and tighten up the two screws (2) again. The appliance is now
ready for work again.
