GENERAL MACHINE PARTS

At present, the baths in the machines are coated with high temperature paint in order to prevent any wetting of the solder to the Cast Iron thus reducing their life.

The basic recommendations are; to thoroughly clean the baths and have them resprayed with the high temperature paint, rubbed down, make certain that there is no excess paint on the material, and sprayed again. This would ensure that there is a sufficient barrier between the solder and the Cast Iron and it should be checked each time the solder is completely removed and renewed in the machine.

Although Cast Iron nozzles can be used in Pb-free solder, measures should be taken to ensure that when they are sprayed, all surfaces are covered with high temperature paint to reduce wear.

If excessive wear becomes apparent the nozzles would then need to be made from Titanium, as does the pump worm but would not need the high temperature paint.

The use of wetted nozzles and tips will be affected by the change to Pb-free solder. The wear on the nozzles and tip will increase by approximately 40%. It is not possible to use a Titanium tip on any nozzle and still maintain the wetted surface to aid the soldering process, it is therefore recommended that all customers using said parts carry spare nozzles and tips.

Note:

It is recommended that the maintenance of the machine incorporate gentle cleaning of the bottom and the sides of the inside of the bath as part of the daily dedrossing routine, without scratching the paint.
Pillarhouse is dedicated to sourcing alternative materials that can be used within our machines soldering system to help reduce wear and maintenance.
