Which CO2 Laser Tube Is Best – DC or RF?

The answer can be both, depending on the needs you have and laser cutter budget. Both wine glass (DC) and material (RF) pipes have their advantages, with regards to the application.

Metal laser tubes have for many years been the industry standard. Nonetheless, they are expensive to manufacture and consequently you will outlay additional money to acquire an investment of this type.

Glass laser tubes were created as a cheaper source of power, predominantly for cutting. Seen as a consumable, a quality glass laser pipe should still give you three or four many years of service.

‘Do I need details engraving?’

This is possibly the most relevant question you should consider. If beautiful, precise engraving is not a requirement in your decision to buy a laser, outlaying more capital in the purchase could be a wasted investment. However, if the answer is yes, then your cost boils down to the brand and working area that best meets your needs and budget. Generally, a quality “brand” name co2 laser tube equipped with a metal laser tube could depend on three times the price tag on a reputable CO2 laser beam installed with a goblet laser tube.

You will find other factors and features that need to be considered with metal tube lasers, aside from merely the pipe itself. These may differ from brand to brand, and many have features that some wine glass tube machines do not have and for that reason must be considered in the pricing.

Glass (DC – Immediate Current) Tube

A less expensive laser source that uses high DC voltage to fire a slow-moving pulsing laser. They require a standard water chiller to cool the pipe and also have a shorter lifespan as high as approximately 3-4 many years of modest use before they can be replaced.

They are a very capable laser cutter due to the typically higher wattages and will engrave. However, the quality of the engraving is immediately dependent on the manufacturer’s investment in the motion control system, DSP (digital transmission processing), optics, and the make of the laser tube itself. There are plenty of manufacturers of wine glass laser tubes,and some will last much longer than others. An inferior wattage glass tube (e.g., 40W) tend to provide better engraving results because of the ability to regulate the beam better at lower ability settings.

METAL (RF – Radio Occurrence) Tube

A far more expensive laser source that uses radio occurrence to fire an easy pulsing laser cutter with extremely quick repeatability. Most steel tubes are air cooled aside from higher wattages (150W and above), which can be regularwater cooled. They engrave with ultra-fine detail, due to a smaller laser area size. They have a longer life expectancy of up to approximately 10-12 many years of moderate use before the gas depletes and need to be refurbished or changed. Downtime must also be considered when refurbishing is necessary. It’ll be required to return the pipe to your provider or direct to the manufacturer.

Turn-around time occasionally can be quite long. See more.


Lifespans quoted by the product manufacturer can be full range and are merelyspeculative. Many factors will determine how long a laser beam pipe of any development can last,but we can say for sure that a preventative maintenance program can track the condition of the tube during its time in service. Following the guidelines prescribed by the product,manufacturer is an effective way to ensure you get the most out of your laser cutter, whichever way you choose to go.
