You may see some less-expensive laser systems on the market in the 10- to 12-watt range. I don’t suggest less than 30 watts of power for a laser system because the lower wattage systems don’t have enough power to run most projects and have to engrave at extremely low speeds to etch any depth in most materials.
There are also glass laser tube systems on the market that you should be wary of. These laser tubes need to be replaced much more often. There is also a visual difference in the engraving quality from these laser sources. Most manufacturers of these systems are located in Asia and are not currently able to provide the service or support that you need.
Talk to your sales representative about the support you can expect from both the equipment manufacturer and from the distributor. Your engraving business depends on your laser being up and running, so it’s important to know the company you’re working with is responsive and reputable.
