41 ALL RIGHTS RESERVED © SOLDERING STEPS 2.8 PREPARATION • Always wear safety glasses. • First, remove any parts that will be affected by heat, e.g. pads, rim cover, temple tips. • Before heating, it may be necessary to apply a large amount of protective heat shield paste ISOFLAM (Ref. 06221) over those parts that are close to the area being heated. • Next, remove broken part by heating the area until it becomes detached. Use tweezers Ref. 03730 to help. POLISHING AND DEGREASING • Always prepare the surfaces to be soldered first by using the rubber abrasion wheels (Ref. 02444 - Ref. 02447). A clean, smooth surface ensures a good result. • Alternatively use a file. PROTECTION OF THE PARTS CLOSE TO THE SOLDERING POINT • Before soldering it may be necessary to re-apply a large amount of protective heat shield paste ISOFLAM (Ref. 06221) over those parts that are close to the area being heated. POSITIONING OF THE FRAME • Place the frame on the soldering table (Ref. 06195) to give easy access to the part being soldered. The clamps should be kept away from the soldering area to avoid overheating. • Rest your elbows to support the hands. • The parts to be soldered should not be close to the table top. PLANNING THE SOLDER Decide on which solder to use. • Always heat up the thickest surface first, since it requires more time to reach the solder’s melting point. • Work over the tray area.
