E3A AC Cross Yoke for Corner Welds

E3A AC Cross Yoke for Corner Welds

Articulated legs adjust to Angles from 60°–130°

Increase productivity – cuts inspection time by more than 50%

Cross-yoke inspects for flaws in all directions Multi-directional magnetization changes field direction at line phase frequency (60 Hz).
Each direction is magnetized alternately every 1/30 of a second.
