Three Important Figures When Assessing Tubes for Laser Cutters and Engravers

Today's laser cutters and engravers are capable of some impressive things and can be obtained at truly reasonable prices. Just about every such machine relies on one particular process for the generation of the laser beam that allows it to do work.


The laser tubes that lie at the hearts of most such machines contain gases in a strategically determined mix. When electricity is introduced to this gaseous blend, a laser beam emerges from one end. Tubes like these vary in a number of important ways, with most of the details being easy to understand.


How One Laser Machine Tube Might Differ From Others


Most types of laser equipment will allow for at least a bit of leeway when it comes to deciding which tube to use. On the other hand, there will also normally be a number of requirements that cannot be negotiated or altered. Some of the ways by which certain tubes differ from others can include:


Operating and instantaneous voltage. The voltage applied to a tube is one factor that contributes to the determination of the resulting power. In most cases, a relatively high amount of voltage will be required to actually trigger the laser-producing effect, after which a lower level will be enough to maintain it. Tubes will normally be labeled prominently with regard to both figures.


Amperage. Every tube has a certain amount of internal resistance, and this combines with the voltage applied to it to establish how much current will actually flow. While manufacturers only rarely report resistance figures, expected amperage levels will normally be available.


Power. Knowing co2 laser tube replacement and voltage is enough to establish how much power a given tube will produce. On the other hand, the usefulness of this metric means that it is the one most commonly emphasized by manufacturers and sought out by buyers. A 100 watt CO2 laser tube will not provide as much cutting or engraving capability as a 150w laser tube or an even larger one, so the power rating often makes for an easy way to assess different parts.


Figures That Translate Into Function


Naturally enough, laser tube prices tend to vary according to the levels of these ratings and others. Tubes that are designed to be used with higher voltages or are capable of converting more power will normally be more expensive than others. While there are also co2 laser tube replacement to take into consideration, these basic ratings often provide a good idea regarding what a particular tube might be used for.
