The Western Instruments WE-3 Standard AC Yoke is the world's most economically priced AC Yoke. Manufactured like competitive Yokes, it is our economical alternative to our premium quality WC-Series models.

The WE-3 is a lightweight AC Yoke, used for MagneticParticle Inspection, to quickly find surface defects. The WE-3 is Westerns economicalalternative to our premium quality W-6 and WC-6 Models. This handheld Yoke has borrowed many of the low cost features of competitive ACYokes, so we do not recommend it for use in Wet Method Inspection. The WE-3 has many superior features, such as its ergonomic grip, Urethane Rubber Housing, and Quick Change Switch.

The ergonomically designed housing combined with its light weight, reduces operator fatigue and strain permitting better and longer inspections. The compact design allows the WE-3 to fit into confined spaces better than full size Yokes. The urethane rubber housing provides superior durability in rugged environments, so the WE-3 is suitable for the high Arctic or the Sahara Desert.

The WE-3 lifts over 10 pounds, exceeding ASTM or ASME specifications for AC Yokes. Magnetic Particle Inspection, with an AC field, is the fastest and easiest way to find surface discontinuities. The AC field provides maximum magnetic particle mobility, which cause the particles to migrate quickly and congregate at defects. Demagnetization is simple with this one man inspection; the operator simply activates the Yoke while pulling it off the workpiece
