phaser

pulsed micro arc dental welding units

the primotec dental phaser welders based on pulsed micro arc technology are optimized for easy, fast and reliable welding of all types of dental welding jobs. More info...

 

laser quality welding at a fraction of the cost

welding ALL dental alloys, including Palladium-Silver, even 
easier, even more gentle and even more versatile.

uses

Wide range of applications:

With the primotec phaser micro impulse welding device you can weld:

  • all new dental products or repairs
  • all dental alloys and monometals (titanium)
  • also different alloys (hybrid, e.g. "gold on steel")
  • many welding tasks on orthodontic appliances

easily, safely and reliably.

The 10 preset programs of the phaser devices cover all common alloy types and welding situations in the dental field. Alloys that were previously considered "difficult to weld", such as palladium-silver, are optimally pre-programmed and no longer pose a problem.

Welding in orthodontics is also possible without any problems using the phaser. And if the situation to be welded requires even lower amounts of energy, the new micro mode also offers a solution for this.

technical tipsuseful tips for your workflow

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.
Titanium can only be welded to Titanium.

The angle at which the tungsten electrode touches the weld has a significant influence on the penentration depth. Maximum penetration is achieved when the electrode is placed at a 90° angle to the workpiece.

backgrounduseful background information

Only the latest high-performance electronics are used in the manufacture of primotec phaser micro-pulse welders. Combined with precise and reliable precision mechanics, this results in welding equipment of the highest durability.

The phaser welded connection is also extremely durable and biocompatible, as only the same type of lead material is used. By avoiding problematic solders, material mixes and the associated potential differences and crevice corrosion, as well as the resulting health hazards for the patient, are avoided from the outset.

FAQ´s

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.

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.

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.

Can I also weld without inert gas?

  • Yes - but welding without shielding gas causes heavy oxidation and soot formation at the welding point.
    Without inert gas the spot welds will become porous and loose their stability.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.
