Filament Repair
REPAIR EQUIPMENT
1. Conductive silver composition (Dupont No. 4817 or equivalent)
2. Ruler 30 cm (11.8 in) long
3. Drawing pen
4. Heat gun
5. Alcohol
6. Cloth
REPAIRING PROCEDURE
1. Wipe broken heat wire and its surrounding area clean with a
cloth dampened in alcohol.
2. Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.
3. Place ruler on glass along broken line. Deposit conductive sil-
ver composition on break with drawing pen. Slightly overlap
existing heat wire on both sides [preferably 5 mm (0.20 in)] of
the break.
4. After repair has been completed, check repaired wire for con-
tinuity. This check should be conducted 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.
5. Apply a constant stream of hot air directly to the repaired area
for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area
and hot air outlet. If a heat gun is not available, let the repaired
area dry for 24 hours.
