    as the handpiece can be either free to move or fixed in the handpiece holding arm.
  • Most reliable ignition in the micro level

    At the same time high power reserve at the high end.
laser quality welding at a fraction of the cost

able to weld ALL dental alloys, including Palladium-Silver, even easier, even more gentle and even more versatile.

uses

wide spectrum of uses:

The primotec phaser pulsed micro arc welding units can weld:

  • all dental welding jobs, no matter if it is for new restorations or for repairs
  • all dental alloys and mono metals such as Titanium
  • different alloy combinations such as precious to cobalt-chrome (Hybrid)
  • many welding tasks on orthodontic appliances

 easily, safely and most reliably.

The 13 preset programs of the new phaser welding units cover all current types of alloys and welding tasks in the dental field. Alloys, commonly known as difficult to weld, such as Palladium-Silver are now perfectly preprogrammed and no longer critical.

working procedure

technical tips

Especially Palladium-Silver alloys and Cobalt-Chrome alloys with relatively high carbon content are said to be difficult to weld. Because of the almost eutectic behavior of these alloy types, micro cracks in the welding spot tend to appear easily.

Due to the specially developed pulse shapes with HF overlapping for these alloy types this problem can now be considered as solved. However, if material needs to be added, the welding wire for Palladium-Silver alloys has to be of high gold content. As for Cobalt-Chrome alloys, it is a must to use machined carbon free wires only.

Always remember that the weld or arc comes from the work back to the hand piece. The hand piece does not “shoot” a weld. When adding metal back always keep the welding wire between you and the electrode.

background

The primotec phaser is a pulsed arc micro welder developed to make dental welding accessible and affordable to all dental laboratories.

It provides the exact same quality welds as a traditional laser welder (see study). Argon gas flows through the hand piece and focuses on the welding area creating a clean and oxygen free environment, leading to stronger weld joints. The welding or heat affected area is so small that it can easily be done next to acrylic or porcelain. Individually adjustable time and power allow exact control over the welding spot diameter and penetration depth. This allows for welding of all dental alloys.

FAQ`s

1.    Which alloys and metals can I use for welding?

  • All precious metal alloys containing gold, silver, platinum and palladium.
  • Cobalt-chrome alloys, nickel-chrome and titanium.
  • with certain limitations (depending on the alloys), aluminum, stainless steel, tin and most brass alloys.

2.    Do all alloys behave the same during welding?

No – the welding result depends on the melting range and the thermal conductivity of the alloy. For example, the lower an alloy's thermal conductivity, the less energy (power X impulse time) is required to melt it.

3.    Can I weld right next to acrylic and ceramic?

Yes – the heat-affected zone during welding with the primotec phaser is comparable to the heat that develops during laser welding.

4.    Can I also weld without inert gas?

  • No – welding without inert gas produces strong oxidation and soot formation at the welding site. Moreover, it is not possible on the phaser because of its Auto-Stop function.
  • Without inert gas the spot welds will become porous and loose their stability.

5.    Can I use a different inert gas besides Argon grade 5?

In principle, yes. However, we recommend Argon grade 5, because we have obtained the best results with it.

6.    How much gas is consumed during welding?

Each spot weld consumes about 0.1 to 0.2 liters of gas. A 10-liter bottle contains 2,000 liters of gas. That means more than 10,000 welds per filling.

7.    Can I use welding wire?

Yes – we recommend welding wire made of the same kind of material with a thickness of 0.35mm to 0.50mm.

8.    Can I add solder?

No – Solder tends to "scorch" because of its low-melting components. That is the reason why you should never weld on solder points.

9.    How deep do spot welds penetrate into the material?

The penetration depth depends on the energy settings for welding (power X impulse time), the thermal conductivity of the material to be welded and the angle at which the electrode tip is held.

That means that the higher the welding energy and the lower the thermal conductivity, the deeper the penetration of the spot weld will be.

10.    Can I weld different alloys together?

Yes – You can even weld together alloys that have very different properties, such as gold with cobalt-chrome alloys.
Titanium can only be welded to Titanium

11.    Can the spot welds take up tungsten particles from the electrode tip?

  • If the phaser is not operated properly, it cannot be entirely ruled out that tungsten particles may end up in the spot weld.
  • However, this is highly unlikely when the phaser is operated properly.

 Advise: Always work with a sharpend tungsten electrode

12.    How thin can the material to be welded be?

Depending on the material, it should have a minimum layer thickness of 0.1 to 0.2mm.

13.    What kind of operating and maintenance costs can I reckon with?

  • The welder is maintenance free.
  • Under normal operating conditions, you only have to pay the low costs for Argon gas and for wear-and-tear of the electrodes.

14.    How many spot welds are possible with one electrode?

Since the tips of tungsten electrodes have to be sharpened, they get shorter over time. Electrode lifetime is about 1,000 spot welds.
