Stress Relieving Of Wires; Procedure For Soft Annealing, Tempering And Stress Relieving - DENTAURUM Master 3000 Manual Del Usuario

6.3.3 Stress relieving wires
When spring hard wires are bent, stresses are created in their crystalline structure. The bent wire
element can be stress relieved using a suitable heat treatment process. This is done by heating the
wire to approx. 550 °C / 1022 °F over a short period of time. Heat color, dark red.
Remember that stress relieving wire elements on the model takes longer as the plaster absorbs
a considerable amount of heat. Refer to 6.3.4 for the subsequent procedure.

6.3.4 Procedure for soft annealing, tempering and stress relieving

Important!
1. Turn the upper electrode head on the "click-stop" holder  one half turn (45°) to left or right.
!
The upper and lower electrodes must not touch each other.
Should they touch each other, a fault signal is given.

2. Fit the hand electrodes into outlet  and  and clamp the notched electrodes
REF 081-501-00 into the clamping sleeves.
3. Connect the foot switch to outlet .
4. Turn power switch  to position "I".
5. Press pad . The figure last set (e. g. 50) now appears in the LCD display.
6. Set pad  or  for continuous heat control to a low figure, e. g. 0 -> 05. Increase it depending
on the material's cross section. Carry out tests!
7. Set the notched electrode tips in the area of the wire to be heat treated.
