Air Assist Nozzle (Just the Nozzle)

Description

7W, 7W+ 7W PRO Air Nozzle

Dual PRO 14W Air Nozzle

The kit includes a precision machined aluminum air nozzle with specific attention to increasing the air flow without obstruction of the laser beam.  The nozzle has a 6mm air hose attachment that fits with the custom shielding cover.  Changing between using the air nozzle and not using it is simple and easy.

Installation Instructions

The air assist nozzle will work with the 7W and 7W PRO lasers with the fan in front of the laser heatsink.

1. First, we will start by taking off the nut on the air nozzle intake.  Unscrew it and don’t lose it.

2. Put the air nozzle over the lens with the air intake pointed to the front.  Use the M4 screws and attach the nozzle to the front of the heatsink.

3. Use the other M4 screw and finish attaching the nozzle to the heatsink.

4. Take one end of the air tubing and put the orange shielding acrylic piece on the tubing with the logo facing forward.

5. Take the air nozzle nut that you took off in step one and put it on the tubing next.  Make sure it is on the correct way as shown in the picture so you can screw it back onto the air nozzle.

6. Take the air tube and put it on the hose barb of the air nozzle.  Push it all the way on.  If it sticks, then get some soapy water to make it so it fits on all the way.

7. Take the nut and put it down so it hits the threads.  Screw it onto the air nozzle until it is tight.  Hand tightening should be ok, but you can use a wrench to tighten it the last bit as well.  Do not overtighten it though.

8.  Put the shielding piece in the tab on the top and press it into place.  You can use your fingers to push out the sides to allow the plastic to hold under the tabs.  Make sure you get it over the air nozzle for it to fit correctly.

9. Finished!  You are now ready to install it back on your magnetic mount on your machine and hook the other end to your air source.

Recommendations for Use

1. Select a pump with correct air flow for your application.  If you are just engraving, then a lower volume air pump will work because you are just trying to get the smoke away from the burn area.  If you are trying to cut though a material, then a higher volume pump will be required to achieve better cut results.
2. If cutting, lift the material off the waste board using the material risers.  This will allow the smoke to exit the bottom of the cut as well as through the top.
3. If cutting and you don’t want to ruin your waste board, put a piece of metal under the material so it won’t mark the MDF waste board.

Adding air can be dangerous.  Here are some things to follow to make it safer:

1. Never cut or engrave on anything flammable using the air assist.  This includes cutting such items as foam and thermoplastics like Lexan and ABS.  If you have issues when not using the air assist for flare ups, it is just going to be worse with the air assist.
2. Never leave the machine unattended when using the air assist, especially when going slow.
3. Do not go under 10 inch/min when using the air assist.  Going too slow will cause flare ups in the material.
4. Turn off the air immediately when finished with a cut or move the laser from the cut area.  If you leave the laser with the air on at the end of the cut it can fuel embers that can start a fire.
5. Do not leave it unattended.  Did I say never leave it unattended already?
6. If you have to go to the bathroom, pause the program and turn the laser off.  Do not leave it unattended.
