I've wandered between 5mw up to 50000mw over 40 years of laser experience, and an important thing to know is that the laser, although I have not officially tested it, is kicking out the 4, 000mw it claims, and might even be a little closer to 5 or 6,000mw, it's power output from my experience tells me you're getting exactly what they advertise, and perhaps a bit more. I consider it an excellent purchase, but with one caveat, this needs to be run with a pwm module, if not, you can wire it directly to your power supply, (Whether that be a 12 volt plug in adapter or a regulated power supply) no harm will come to the laser from this type of hookup. This is perfect for the laser enthusiast who does not intend to engrave with it and wants to hook it up directly to a 12 volt DC power source, I suggest using one that is rated at 3 amps or better. One final thought, if you wish to connect it directly to a DC power supply you must also connect the pwm module lead, (yellow) to the positive, (red) lead to get it to function, just remember if you do this it runs at 100% power all the time, but won't hurt the module. To simplify, you will have to cut off the connector of your power supply, and one end of the three lead red-black-yellow connector cable and solder those two together cables together, so basically you have a black to black connection, a red to Red connection, with the yellow lead also connected to the red to red connection. Simply plug in the connector to the laser module, then plug in the adapter, I suggest using shrink tubing on all solder connections. Watch out though, at 100% power even if highly unfocused at 3 to 5 ft will cause painful burning on your skin within seconds. ## Features - 【Laser Module】4W (4000mW) optical laser power output.

Also can set the same table up for CNC Oxy/Fuel cutting as well. Even are options to swap out the plasma cutter for a router to carve and cut wood as well, some have digital hight control to cut uneven material like diamond plate or corrugated steel. And there are options for cutting pipe as well. Many people have made there own and yiu can buy units as small as 2'x2' table cut size or up to 4'x8' and even bigger than that. Some have nesting software that will arrange all of your cuts ro use the least amount of material. And say you have a 4'x4' table but need to cut a 4x8 or bigger sheet of steel, you can cut 4' then slide the steel so it can get the remaining 4 feet and so on. A plasma cutter than can cut 1/2" steel plate cleanly will not cost thst much but I personally would get something that can cut up to 3/4" (or even 7/8" to 1") cleanly. Do not get a machine that can barely do 1/2" or you will be cutting slow and maxing the machine out possibly using more consumables and not having a clean cut (if your looking at lasers I assume you want a clean cut, even by hand using guide steel to run up against I can produce some very clean plasma cuts and CNC can do even better). Dont look at the sever capacity only look at the clean cut capacity and get it slightly oversized. If you want a cleaner cut than CNC plasma can do and any dressing of the material after the cut isnt an option then if you can afford it look into waterjet tables over laser. A benefit of waterjet over plasma is not having thr heat that is associated with cnc plasma or CNC oxy/fuel. I have used hand crank devices that attach to large well casing via a chain and you jabe an adjustable oxy/fuel torch head. You line it up have the large 24" or 30" casing on rollers and you slowly rotate the handle to roll the torch around while rotating the casing in rollers and with this I have seen very impressive smooth and beveled cuts. So CNC plasma will suffice for 90% or more of people out there! **Q: Le queda ala máquina atomtrack?** A: Yes **Q: I cannot find any documentation on this module. Does it need a laser driver? Do you have any links to documents or recommendations?** A: Hi friend, Thanks for your question. Please send us the control board of your laser machine directly and contact us. We will give you the appropriate connection. The reason different customers have different control board and operation software,so it may have some different operation mode ,we can not give a same manual. Hope you can understand. Have a good day! **Q: Can I attach to Twotrees ts-55 engraving machine?** A: Yes, you can attach it to Twotrees ts-55 engraving machine ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect *by S***K on 26 January 2026* ### ⭐⭐⭐⭐⭐ Very good performance *by K***E on 23 April 2022* This little powerhouse gives you that extra kick needed, with a pwm module it is very tunable, has an awesomely tight focal point, and even at 100% power stays relatively cool and the forward air flow through the heatsink/body pushes smoke away quite easily, for less than $60 I doubt you're going to find better, at least in a DPSS laser module.
