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, and in the technical data (Appendix 1) at the back of the manual. 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 main 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 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).
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.
Correct Incorrect

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.
Correct Incorrect

For Swing Arm Yokes: Swing the yoke out towards the front of the heater until it falls in the
positioning lock of the hinge construction. Slide the workpiece over the yoke till it lies in the middle
of the yoke and swing the yoke with the work piece mounted back on top of the poles.
