Soldering

!!
When soldering, always wear safety goggles. If soldering takes too long, the
soldering carbon is damaged.
!
When using hand electrodes for soldering or heat-treating, the electrodes must not
touch each other at the electrode holders. However, if they do touch one another, a
fault signal is given. If the carbon electrode is used, the current flows through the
electrode holder and through the hand electrodes, causing poor soldering results.
• F or soldering purposes, one of the copper electrodes is replaced by a carbon electrode
(soldering electrode REF 085-300-00). The heat created by the electrical resistance is stored
mainly in the carbon tip, whereas the metal parts themselves absorb only a slight amount of
heat. The soldering process differs from the welding process by using solder and flux.
• D uring electric soldering, the carbon electrode leads to continuous heating until the solder
is melted. This then flows around the metal parts which are also heated and protected from
oxidation by the flux.
• B efore soldering, the carbon electrode should be cleaned with the emery file, REF 083-300-00
to remove any flux residues, which have an insulating effect and would hinder the flow of current during the next soldering operation. Replace the carbon electrode before the brass
sleeve and the electrode shaft begin to char.
• W e recommend using a pencil sharpener to sharpen the soldering carbon REF 081-601-00.
To increase the conductivity of the soldering carbon, dip the tip in water before beginning
the soldering operation.
• The hand electrodes are not suitable for continuous soldering.
• T he soldering carbon offers more resistance to the current than the clamping electrode
REF 081-701-00, thus causing heat to build up in the tip of the soldering carbon. Always
ensure that the carbon tip is placed where the heat cannot damage the parts.
