Summarize
Model ZL-YW601C is a magnetic particle flaw detector that uses a
magnetic yoke to magnetize ferromagnetic workpieces with AC and DC
magnetization. It can magnetize various parts, including local
magnetization for large parts, and can be used as an additive
method of magnetic flaw detection and remanent magnetization method
of magnetic flaw detection.
The instrument utilizes SCR to form a non-contact switch with low
noise and long life. The instrument is small in size, light in
weight, with large lifting force and adjustable joints, especially
suitable for flat weld, fillet weld, pressure vessel, pipeline and
the detection of complex shaped parts. The output of the instrument
is low voltage, which is more suitable for the occasions where high
voltage is not allowed to enter the equipment for flaw detection.
The flaw detector has AC and DC magnetization function. It can be
equipped with A-type, D-type, E-type and O-type probes. The machine
can be DC full-wave rectification magnetization, AC magnetization
can detect deeper defects from the surface.

Structural Characteristics:
The instrument adopts silicon controlled switch, low voltage output
is safe and reliable, the probe adopts fixed and plus adjustable
two kinds, adjustable probe can be adjusted according to the shape
of different parts of the pole shoe spacing, and have good contact.
Operational Use:
Insert the round plug of the power cable into the three-core power
socket of the instrument, and insert the single-phase plug of the
cable into the socket of the power grid distribution board, (there
must be a solid grounding wire) turn on the power switch of the
instrument, and the indicator light will be on to show that the
circuit has been connected to the power supply.
Insert the aviation plugs at both ends of the cable into the
instrument socket and the probe socket respectively.
So that the probe and the surface of the workpiece to be explored
contact good, press the magnetization button on the probe,
magnetization indicator light, indicating that the workpiece has
been magnetized.
Turn off the instrument power switch and the main switch on the
grid distribution board when you stop using it.
Cautions:
When using the instrument, the probe and the workpiece being probed
must be in good contact before pressing the magnetizing button,
otherwise the current in the coil will increase and burn out the
fuse, or even damage the SCR.
If you need to adjust the magnetic pole spacing, loosen the
butterfly nut on the adjustable joint to change the magnetic pole
spacing, and then tighten the nut to work.
