Magnaflux Y-7 AC/DC Electromagnetic Yoke Kit – 230V
The Magnaflux Y-7 MV Kit is a complete, field-ready magnetic particle inspection kit built around the Y-7 — a durable, high-strength AC/DC electromagnetic yoke engineered for demanding inspection environments worldwide. Solid-state controls allow the operator to switch between AC magnetic fields for surface indications and DC magnetic fields for sub-surface indications, making the Y-7 the most versatile yoke in the Magnaflux lineup.
Configured for 230VAC operation, this kit is ideal for international job sites, offshore platforms, and industrial facilities outside North America. Featuring sealed chemical-resistant construction, articulating legs to contour to any part shape, and a robust strain-relieved cord, the Y-7 MV Kit delivers everything needed for non-fluorescent magnetic particle testing right out of the case.

When to Use AC vs. DC on the Y-7: The Y-7's dual-mode capability is one of its most powerful features — but knowing when to switch modes is critical for reliable defect detection.
Use AC mode for detecting surface-breaking defects. AC creates a "skin effect" that concentrates the magnetic field at the part surface, making it highly sensitive to tight surface cracks, grinding cracks, and fatigue cracks. AC also provides a slight particle-agitating effect that helps particles migrate to indications.
Use DC mode when you need to detect sub-surface defects or inspect through coatings and paint. DC produces a deeper, more uniform magnetic field that penetrates further into the material — ideal for finding subsurface inclusions, laminations, or defects beneath non-conductive coatings.
Remember: DC yokes require a minimum 40 lb (18 kg) lift force per ASTM E1444, vs. 10 lb for AC. Always verify with a certified yoke test weight in the appropriate mode before beginning inspection.
Applications
- Weld inspection on pipelines, pressure vessels, and structural steel
- Surface and sub-surface defect detection on castings, forgings, and machined parts
- In-service inspection of aerospace and industrial components
- International and offshore job sites requiring 230V-compatible equipment
- Inspections requiring both AC and DC magnetization from a single tool
