Setting Up The Work Piece - Bessey PV Series User Manual

5. Setting up the Work Piece

WARNING!
 Use appropriate hoisting equipment for heavy components and yokes. The manual
lifting of heavy objects is a common cause of injury.
 The weight of the work-piece should not exceed the maximum weight shown in section
5.2 below. Exceeding these limits may result in catastrophic equipment failure leading
to personal injury.
 If heater is equipped with sliding horizontal supports, always secure these with the
designated safety pin, in either the 'in' or the 'out' position. Unexpected movement of
the work piece may lead to personal injury.
 Ensure that the power supply cable cannot come into contact with the work piece.
Damage to the cable may result in electrocution.
 Never support components with a metal cable or have any cables hanging in the
proximity of the magnetic field. Extremely high currents can flow through the cable
causing it to heat up quickly, resulting in a risk of burning.
The work piece can be set up in two different ways:
Yoke passing through the work piece
Larger work pieces can be isolated from the environment by packing them in isolation material like
a welding cloth. This will keep the heat in the work piece and will avoid that the heat is transmitted
to the air.
5.1 Setting up the work piece where the yoke passes through it

Make sure that the bright sides of the yoke
are lubricated sufficiently (improve contact,
avoid excessive vibration) and are aligned
on the top of poles. Use supplied lubricant.

Always choose a yoke, which fills the bore
of the bearings as fully as possible. You
can even combine 2 yokes - this helps to
heat more quickly & evenly.
Yoke in the horizontal position
(The bore is large enough for the pole to pass
through it. The work piece in this example is
shown resting on the horizontal supports).
