Air Filter System

Do I need a separate air filter for my air plasma system? The cut quality, performance, and consumable life of any air plasma system are directly impacted by the quality of the air going into it. Not only is it important to make sure you have enough air; you also need to make sure the air you have is clean and dry. This is especially important in areas with humid weather, as this excess moisture will easily make its way into your air compressor tank and air lines. If this should be the case, we suggest draining your tank at least once a day or better yet, installing an automatic drain system. In addition, you may want to add a second filter (in addition to the filter already inside your plasma unit) at least 20 feet downstream of the compressor, to help collect some of this moisture. If you plan to use your system a lot – in a production environment, for example – or live in an area with extreme humidity, then you may need to use a refrigerated air dryer or desiccant filter system to remove moisture.

Marker Slippage/Inconsistent Placement

Sometimes the markers placed in the marker holder slip freely and fall out of the holder. Other times they get jammed up into the holder and are impossible to remove. We recommend a black or silver Sharpie for this. If the silver Sharpie still slips out of its holder, wrap the marker in tape (we use duct tape, but any tape will do) to ensure that it is held securely in the marker holder.

Or

Simply flip the head of the marker holder to the other end of the cylinder and the opposing end should accommodate both black and silver Sharpies.

Marker Revival

Sometimes the markers will dry out because they are marking close to a cut zone where the tubing is still hot from the plasma. This can dry out your markers in record time. To bring your dried out marker back to life, dip the tip in some rubbing alcohol and it will work as good as new. It is also smart to make sure that your tubing is wiped down before running the stick to make sure that the grease doesn't inhibit the marker's ability to show up well on the surface.

Engraver Maintenance

To ensure that your engraver tip lasts as long as possible, we suggest that you invest in an airline oiler and install it in your air line as shown here.

Engraver Tip Replacement

Sometimes, regardless of preventative maintenance measures taken, the engraver tip will be in need of replacement. In this case, this stylus tip can be purchased at the link available here.

Rail Maintenance

Your Bend-Tech Dragon machine will require maintenance in is lifetime. The following is a small routine maintenance process that should be completed about once per week, or if you notice build up of grime or dirt on either the main rail or on the roller bearings of the chuck trolly. This process should take less than 10 minutes to complete.

Step 1) Send the chuck to the middle of the machine. (Either jog the machine to this location or manually move the chuck while the machine is off.)

Step 2) Wipe down the entire reachable surface of the main rail. The section under the trolly will not be accessible during this step.

Step 3) Begin the homing sequence. (Click the "Ref All Home" button in your Mach software)

Step 4) During the homing sequence for the X Axis, carefully wipe off the roller bearings on the chuck trolly as they are rotating at this slow speed from the homing sequence. (They tend to accumulate grime and dirt during the operation of the machine.)

Step 5) Wipe down the section of the main rail that was covered by the trolly before the homing sequence.

This will provide a clean working environment for the chuck trolly to roll on and will increase the life of the trolly bearings. To ensure that your rail/beam remains in pristine condition and operates up to our standards, make sure to follow through with this process as needed.

Frayed or Broken Z-Axis Cable

Anti-Chattering Retro Fit Assembly Manual

In some cases with older model 21 foot machines, some operators have experienced excessive chattering on the X-travel which has led to jagged or wavy cuts. If this unfortunate phenomenon has been the case for you, we suggest that you contact us and we will send out a retrofit kit to resolve this issue. The assembly manual is located below.
