The 20W laser marking machine is our most commonly used laser marking equipment. Many people don't know this concept. How powerful is a 20W laser marking machine? Actually, this 20W shows the power of the machine. Let's see the detailed introduction.
20W Laser Marking Machine, as the name suggests, 20W, 20W power, W is a unit that physically describes power, the full name is Watt and the symbol is Watt. The definition of a watt is 1 joule per second (1 J/s), which is the rate of energy (measured in joules) that is converted, used, or dissipated per second. In the electrical system of units, it is volts times amperes (VA). In everyday life, the kilowatt is most often used: 1 kilowatt = 1000 watts. So 20W is 20W and the actual power is derived from the laser data.
When purchasing a laser marking machine, be sure to check the power of the laser marking machine. The actual power of a 20W laser marking machine is 20W. We have many common types of lasers such as fiber lasers which include 20W, 30W, 50W and 60W machine. Conventional carbon dioxide lasers also include powers of 20 W, 30 W and 50 W. There are also 3W, 5W and 10W UV lasers. UV lasers also tend to be more expensive and are suitable for fine marking.
Based on the above, the power of a 20W laser marking machine is 20W. The actual power of a laser, such as a 20W laser, can actually be as high as 24W. Generally, when choosing a marking machine, 20W power can mainly meet our usage conditions. If the depth of the product marking is not important, it is recommended to use 20w.
Below are the relevant parameters of 20W laser (for reference only):
