2.1 Intended use The Master 3000 is only intended for welding and soldering of orthodontic appliances. The use of the unit for any other purpose is prohibited. The use of the unit for its correct purpose also includes compliance with all the instructions contained in the Instructions for use ...
Dentaurum Customer Service’s personnel or authorized service technicians. When a Dentaurum product is taken out of operation once and for all, the disposal regulations of the country of operation apply. Dentaurum or the dental trade is available to answer questions regarding the correct disposal of any specific product.
The unit is now ready for operation. 7.1 Setting language of LCD display The Master 3000 is able to display five different languages on the LCD display. These languages are: German (manufacturer’s setting) English French Italian Spanish...
In order to meet the complex requirements for constructing orthodontic appliances, the Master 3000 is fitted with 7 different copper electrodes for welding. These have special contact tips or surfaces.

Spot-welding crossed wires Where the wires are simply crossed, a single spot-weld is usually adequate to connect them properly. In many cases, it is advisable to solder the wires in addition to welding. In this case, please take into account that heating the wires when soldering them to strengthen the joint also causes the mechanical properties of the wires to deteriorate.
8.1.2 Spot welding with hand electrodes (optional accessory) This process is recommended when for example wires have to be fixed against one another on the model. The components removed from the model should then be re-welded or soldered at the click-stop electrodes.
Recommended accessory: Connect foot switch REF 080-116-00 to outlet 8.2 Soldering When soldering, always wear safety goggles. If soldering takes too long, the soldering carbon will be damaged. When using hand electrodes for soldering or heat-treating, the electrodes must not touch each other at the electrode holders.
8.2.1 Soldering with the click-stop electrodes First tack weld the parts together with a weld spot. Procedure 1. Turn power switch to position “I”. The previously selected mode appears again. 2. Press pad to select the “soldering” mode. The LCD display now shows “soldering” and the last figure set for soldering energy, e.
8.2.2 Soldering with hand electrodes (optional accessory) Procedure 1. Turn the upper electrode head on the click-stop holder one turn (45°) to the left or the right. The upper and lower electrodes must not touch each other. 2. Push the plugs of the hand electrodes into the outlets 3.
8.3 Heat treatment 8.3.1 Annealing of wires Spring hard chrome nickel stainless steel wires (e. g. remanium ) can be soft annealed at a ® temperature of approx. 1100 °C / 2012 °F (heat color: bright red). Soft annealed CoCr wires cannot be tempered (hardened)! Complex bending operations (especially around tight radii with thick wires, e.
8.3.3 Stress relieving of 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.
Note: To soft anneal thick wires, we recommend placing these on a conductive, heat-resistant base, e.g. a graphite slab. Instead of the notched electrode REF 081-501-00, the clamping electrode REF 081-701-00 in a hand electrode can be used to hold the wire element. To practice the techniques necessary for soft annealing, tempering and stress relieving, we ...
9.3 Function: Printing in “solder” mode 1. Connect the printer to the welding unit as described in section 9.1. 2. Press pad on the welding unit to select “soldering“ mode. The LCD display now shows “soldering” and the last figure set, e. g. 50. 3.
The unit operates under high voltage! To prevent accidents, never open the unit. If malfunctions cannot be corrected in the above ways, please contact Dentaurum Customer Service (see page 20). *Replacing the fuse: Unlock the fuse insert on the right-hand side of the combination plug and pull it out.
