Rockford Systems’ Detect-A-Finger protects welder operators' fingers from injuries

The Rockford Systems RKC-500 Detect-A-Finger drop-probe device prevents serious injuries to welder operators by halting welding machinery from starting its stroke if a finger or hand is detected in the point-of-operation area. To block welding splash, additional lightweight, clear plastic shielding can also be attached to the device's rod.

The key components of the device are a sensing probe module with a rod shaped to fit over or around the workpiece and a control module. When the operator initiates a stroke, the probe is released and drops by gravity. If it detects anything more than the material, it averts cycling. However, if an operator's fingers or hands have not entered the point-of-operation area, the probe will drop into its preset position, and the control unit will allow the welder to operate.
