ALK42, J Tech Photonics 4.2 Watt Laser Kit AR Series

This laser produces an amazing 4.2W of power with included 2.5A driver! Built by J Tech Photonics specifically for any Axiom AR series CNC machine, this is the strongest laser accessory available in the market. The new Axiom CNC laser by J Tech Photonics raises the bar in CNC accessory lasers. Precision laser trimmed regulators for constant current to the laser, 0.01 tuning resolution, digital isolation, soft start, ESD protection, current limiting, and the list goes on.

 

Features:

  • Engrave on wood, leather, acrylics, and many other materials.

  • Cut thin and softwoods like Balsa, Basswood, and many other types of materials like foam, paper, cloth, and acrylics.

  • MAKE incredible objects for projects or production. Your creations are only limited by your imagination!

  • Compatible with all Basic, Pro, Pro+ & Elite Series machines.

The US Federal Government has a list of things that are required for operating these high-power class 4 lasers. They might seem trivial, but they could save your eyesight! Here is a rundown of the safety features that will protect yourself and others:

  • Key Switch – A key is needed to enable the laser. When the key switch is turned on, the laser is enabled and the key CANNOT come out. You can only remove the key when it is disabled. This feature is good if you have curious children or have your laser in a shared area and want to limit its use. Just take the key out and hide it!
  • Remote Interlocks – This feature allows for the addition of a switch on your enclosure so that when it is open, the laser will automatically turn off. An interlock switch is also installed on the rear surface of the laser which insures that if the laser is removed from your Axiom CNC router, the beam is interrupted. They’ve also added an E-Stop button for the laser, which is always good if you need to stop the laser quickly! 
  • Power Fault Protection – In the event of a power failure, your laser will be disabled, preventing the beam to illuminate as the power is restored. Simply press the reset button and you are back in action! 
  • Emission Indicator –  The small little LED on the front lets you know when your laser is on.
