YM5 REMAGNETISER. Should you find it inconvenient to return your YM5 Yoke for re-magnetising, Magnaflux have a specially designed fixture which allows you to re-magnetise it yourself. Simple to operate, using a battery, discharging through coils which have the poles of the YM5 Yoke within them.

YM5 Yoke Serial number: YM5 YOKE KITS The following kits are provided to compliment the YM5 Yoke: Part number: 005K001 Carry case and aerosols (Yoke not included) – supplied as Magnaglo 14HF or Magnavis 7HF kit Part number: 005K024 Carry case only (Yoke and aerosols not included) USING THE YM5 YOKE The Yoke is placed on the workpiece perpendicular to the direction of the cracks. Each leg can be moved in two directions at each joint, and the pole pieces rotate. The operator can then adjust the spacing between the legs from about 25 mm to 250 mm and they can also contour the feet to produce a good flat contact on parts with irregular shapes The operator then applies the inspection medium, either wet or dry, and surface crack indications will form immediately. The inspection can proceed rapidly in a series of steps each finding cracks in a 150 mm x 150 mm area. Since magnetic contact exists only between the Yoke and the workpiece arcing on the part itself is impossible. However, damage could occur through inadequate care when presenting the Yoke to the workpiece. WARNING Check the strength of the Yoke by applying the inspection medium to the keeper bar which has artificial defects. Only remove the keeper bar to carry out inspection work.

In the event of contrast not being ideal for inspection, a thin layer of Magnaflux WCP-2 White Contrast Paint can be applied prior to testing. All powders are of closely controlled particle size and shape and have desirable magnetic properties. For best results application should be as a cloud applied near the surface while the current is flowing. Excess powder settling out can be blown off. 3A Black Maximum working temperature 230°C 8A Red Maximum working temperature 175°C WCP-2 White Contrast Paint Magnaflux WCP-2 is a quick-drying white contrast paint which can be applied as a thin coating prior to testing where enhanced contrast is required. SPECIFICATIONS Magnaflux, Magnaglo and Magnavis concentrates, prepared inks and dry powders meet the requirements of ASTM E-1444 with oil suspended inks and concentrates meeting AMS specifications, plus appropriate industrial and Government specifications, Certifications are available on request.
