	STANDARD MODELS	OPTIONS AND ALTERNATIVES
Power Pack	AC waveform at the maximum rated output current, for duty cycles as below.	HWDC and/or single phase FWDC.
Current Flow Magnetising	Max output nominally 3500A peak as measured through a standard shunt.	Max output nominally 2800A HWDC peak.
Encircling Coil Magnetising	Carriage mounted, 5 turn, 300mm ID, length 100mm.Nominal max output/centre field strength in an empty coil 5600AT AC peak / 17.5KA/m.	Max output nominally 5400 AT HWDC peak for a 300mm ID coil. Smaller coils fit between head/tailstocks.
Flux Flow Magnetising		Head and tailstock flux coils powered with AC, HWDC or single phase FWDC.
Multi-Directional Magnetising		Simultaneous operation of two magnetising circuits, to produce a swinging field.
Current Control System	Variable thyristor with resulting complex waveform.	Variable transformer with resulting sinusoidal waveform.
Working Range	10% to 100% of maximum output.	Extended working range down to 150A.
Metering	Digital on all models. Currents displayed in peak. Accuracy is better than ±5%.	AC displayed as rms (sinusoidal only). HWDC and FWDC output displayed as peak. Accuracy outside of working range is better than ±10%.
Shot Time	A preset single shot of 1, 2 or 3 seconds.	Operator selectable from three preset shot times.
Duty Cycle	Dynamic duty cycle from 20% at max output to 100% at approx 1000A.
Max ON Time	3 seconds at 20% duty cycle.
Demagnetising	Automatic decaying AC.
Headstock	Pneumatically operated, manual control. 100 x 100mm contact pads. 25mm maximum clamping travel. Adjustable clamping pressure.	Foot-switch operated clamping. Alternative clamping travel.
Tailstock	Fully adjustable over bed length, bearing mounted. Manual quick release lock.
Testpiece Support	Removable V-blocks on head and tailstocks.	Detachable small piece device for protection of delicate testpieces. Bed bar mounted adjustable support.
Inking System	50 litre stainless steel covered reservoir with recirculating pump, manual application and integral controls.	Automatic inking as part of the automated process sequence.
Services
Power Supply	240V single phase AC, 50/60Hz, current drawn approx 50A.	The multi-directional magnetising option requires a 415V 3-phase AC + neutral + earth, 50/60Hz supply. Current drawn 65A max.
Air Supply	6 bar (FR unit fitted as standard)
Baugh & Weedon NDT has a policy of continuous improvement, thus this specification may change.
