摘要：
A protective automatic darkening filter (ADF) and an associated tool, such as a welding torch, are controlled by a corresponding communication unit. The invention helps to ensure that the tool is not activated before the ADF has reached its dark state. A communication channel between the communication unit and the ADF may be established using a wired or wireless medium.
