Brass wool: Although less aggressive than the Inox Wool, it is easily subject to deterioration. It will cause metal particles and fibers to contaminate the working area. Customers have refused to use Brass Wool for this reason. Brass wool was first used in industry many years ago and it became standard use in industry and was used by many operators.

Inox Wool: It is more agressive than the Brass wool and so will require more care when being used. It is the most effective when used less aggressively and therefore minimizing the abrasions – Remember! Less Is Better. As well as being more effective, Inox is much more durable than Brass. It is more flexible, less fragile, and as a result, reduces the amount of particles and contamination of the work area. In tests we found it very resistant to breakage and it contained less than 10 times the amount of broken particles than in Brass wool.

Desoldering is a dirty task. When using our DR desoldering tool, it is recommended that you have a spare "tube", clean and set to go during the day. Simply unscrew the green end piece of the gun, remove it from the handle, take the tube off and replace it with the new one. This will allow you to continue working without stopping. Put aside 5-10 minutes at the end of a shift to use the extraction rod to take out the baffle and the filter in the glass or stainless steel tubes.

Take a small wire brush and gently brush the solder off the baffle into a trash receptacle or hazardous waste container (if using leaded solder). Replace the baffle to the mark on the tube and insert a new white filter. You should periodically check the secondary filter at the front (or back, depending on model) of the desoldering pump. Replace it when it looks dirty (discolored).

It is also a good idea to use the supplied drill bit tool to clean out the desoldering nozzles that you use to prevent buildup and clogging. The amount of useage your desoldering tool gets will determine the frequency of cleaning. Please see the manual for additional recommendations.

• Hand soldering
• Soldering with melted solder

1. 1. Dip in soldering
   2. Wave soldering
   3. Drag soldering

• Soldering with solder paste

1. 1. Reflow soldering
   2. Laser soldering

• To make a new soldering
• To repair a faulty soldering (Touch-Up)
• Rework

First of all, soldered to be area is heated with the soldering iron.
As solder wire contacts with the area, the solid flux in the wire melts around at 100°C and spreads on the area which makes it clean.
As solder reaches the melting temperature it melts and spreads on fully.
During the spread, an intermetallic layer is formed and soldering is finalizes.

To choose the correct soldering iron, tip and temperature,
To choose the right solder wire diameter,
To choose the appropriate solder alloy and flux,
Soldering process should be applied correctly.

Hand-soldering is a soldering method where soldering iron is used as the heater as well as flux containing solder wire.
