WORKING WITH THE
SOLDERING GUN
SWICHING ON AND OFF
- Pull the trigger to switch the machine
ON.
- Release the trigger to switch the
machine OFF.
Caution! To avoid the risk of
overheating, the soldering gun
may only be heated for 30 seconds
max. The soldering gun must then
be allowed to cool for 30 seconds.
30 seconds heat up is usually sufficient
to solder 2-3 joints.
SOLDER AND FLUX
Soldering is the process of a making a sound electrical and mechanical joint
between certain metals by joining them with a 'soft' solder. This is usually a low
temperature melting point alloy of lead and tin.
Solder
Solder for the DIY market is produced almost exclusively in the form of wire.
There are two types of solder wire on the market.
1. Simple, unfilled solder wire.
2. Solder wire with flux core.
For best results use a good quality multicore solder.
Flux
Flux is a chemical which removes oxide residue on the workpieces and prevents
oxide residue forming on the joint during the soldering. Oxide residue can prevent
the formation of a clean joint. Flux is most commonly contained in the cores of
multicore solder but is also available separately in paste or liquid form.
SPOTLIGHT
- The machine is fitted with a spotlight which lights up when the trigger is pressed.
- The spotlight is particularly useful when soldering in darker, inaccessible areas.
SOLDERING
Preparation
- The parts you wish to solder must be clean in order to ensure that a sound electrical
and mechanical joint is produced. Remove any oxidisation using a file or spatula
or a chemical solution.
Caution! Do not use aggressive acids such as hydrochloric, sulphuric or
nitric acid unless you are an expert.
- An oxide residue can form on the tip. This should be removed by rubbing the tip
on a soldering stone.
- Coat the tip lightly with flux and tin it lightly with solder wire.
- The correct temperature is reached when the solder melts to a filmy consistency.
If lumps are formed the tip is not hot enough. If beads are formed the tip should
be cleaned.
Soldering
- Ensure that both parts of the joint are clean and heat the joint with the soldering
gun. Hold the solder to the joint until it flows onto the joint.
- Remove the soldering iron from the joint.
