8 10 12 14'' Inner Diameter AC Magnetizing Coil NDT Testing Demagnetization Tool

Technical Parameter

• Power Supply: 220V, 50Hz AC
• Coil Current: Approximately 0-16 amps, can be adjustable

Operation Steps

1. Connect the coil to the AC power supply and press the foot switch. Insert a ferromagnetic object into the center of the coil; a noticeable magnetic force should be felt. During testing, the object to be tested should be longitudinally parallel to the coil's axis and placed as close as possible to the center of the coil's outer circumference.
2. Press the foot switch, and after the coil generates energy, place the object to be tested. By maintaining a certain angle between the object and the coil axis, material defects can be detected effectively.
3. If using wet fluorescent magnetic powder, the coil will generate energy approximately two seconds after the object is placed in the coil; move the component appropriately for comprehensive testing.
4. After the testing is completed, the component can be demagnetized. Simply place the component near the outer circumference of the coil, drag the component 500mm along the coil, and then turn off the power supply. For large components, place the coil above the component and follow the same operation steps.
