Maintaining The Soldering Iron - Wetekom 28 57 67 Bedienungsanleitung

Heating Element
1. Unscrew the knurled nut barrel assembly. Take the tip slowly
out of the heater.
2. Insert a new or cleaned tip as far as it will go into the heater.
Screw the knurled nut barrel assembly to the heater. Do not
use a tool to tighten the knurled nut, only screw by hand.

Maintaining the Soldering Iron

 Dismount and clean the tip every twenty hours of use. If an
oxide film is formed on the tip, it can be cleaned by lightly
rubbing with fine 600 – 800 grit emery cloth.
 An oxide film can also be formed inside the iron retainer.
Remove any loose stains by carefully blowing out.
 After thoroughly cleaning the tip, apply some solder and keep
the soldering tip tinned for a long service life. To remove
surplus solder, heat up and wipe the tip with a wet soldering
sponge in the tray (4).
 If the soldering tip becomes hard to wet, use solder and flux to
reactivate it. Wrap some solder with included flux around the
cold tip and heat the tip until the solder melts.
 Change corroded or burnt soldering tips in time to keep the
unit in good working order. Replacement tips can be pur-
chased under the blow mentioned article numbers.
