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

Moisture in arc shields or ferrules must be removed before reuse to prevent hydrogen-related weld defects. Re-baking at 120 C provides enough heat to drive off absorbed moisture from fibers, coatings, and resins without risking damage to the shield materials or adhesives. Temperatures like 100 C may not fully dry the parts, while 140 C or 200 C could degrade components or adhesives. Therefore, 120 C is the appropriate rebake temperature.
