What is the exact rebake temperature for arc shields or ferrules in Celsius?

• A. 100 C
• B. 120 C
• C. 140 C
• D. 200 C

Answer: (B)

Rebaking arc shields or ferrules is done to remove absorbed moisture from protective coatings and insulative materials so steam doesn’t form during welding. You want a temperature that dries the material effectively without damaging its coatings or adhesive layers. About 120 C hits that balance: it’s hot enough to drive out moisture, but not so hot that it degrades the shield’s or ferrule’s coating, resin, or insulation. Lower temperatures may leave moisture behind, while higher temperatures risk softening or damaging the protective layers. That’s why 120 C is the recommended exact rebake temperature.
