Machine Size (After Assembly): 372”L x 30”W x 72”H The Dragon A400 will arrive in its crate and will need to be opened with a minimum of two people with pry bars and/or claw hammers. The top of the crate should be removed first, followed by at least one large face of the crate as shown here.
Page 2
Upon revealing your new Dragon A400 machine you'll notice that it's packaged into several different pieces, all of which are bolted to the base of the crate with 1/2” bolts. These pieces are also shrink-wrapped to prevent damage due to swaying during shipping.

The Unpacking And Assembly Process DO NOT REMOVE THE SHRINK WRAP AND RATCHET STRAP SECURING THE CHUCK AND CABLING CONNECTED TO THE HEAD OF THE MACHINE. 1.) Remove the shrink wrap and 1/2” bolts securing the rear rail section (green) and the two corresponding leg sections (pink and yellow).
Page 4
The image below shows the machine fully assembled with each of the numbered sections lining up with each other. They are color coded, so pay close attention to the following instructions that refer to any section with a corresponding color after the part description. •...

2.) Using a tin snips or similar tool, cut the banding straps off of the rails that are secured to the base of the crate (blue and orange). Next, remove all of the unsecured parts from the crate and begin to line them up where the tail of the machine will be located in your shop. NOTE: The cable/belt track guide sections that are stacked onto each other on the tail section (green) of the machine can be set aside until step 13 of this manual.

3.) On the front end of the tail (green #5), start by grabbing the four 1/8” allen head screws from the misc parts box. These will be used to connect the tail to rail section 4-5 (blue). 4.) It’s very important to attach the leveling feet (located in the parts box) before assembling each part of the machine.
Page 7
5.) Slide the independent rail section (blue) into the tail (green) making sure to line up the sticker numbers with each other (5:5). Have another person hold the support leg (yellow) into position as this happens. Then, retrieve the bag of screws and mounts from the parts box. 6.) Using the magnet tool provided, guide the T-nut mounts into the sides of the rail and screw the 3/16”...

8.) At the front end of the independent rail (blue), loosely affix the rail to the independent support leg (yellow) using the magnet tool and allen head screws as in the previous step. Make sure that the support leg is level before tightening down any screws. You may need to tap the rail into position using a rubber mallet on the opposite end.
Page 9
10.) Line up the head of the machine (red) a rail’s length away from the independent support leg (yellow) and slide the head towards the rail to close the gap on the second independent rail section (orange). Using the magnet tool, connect the rail section as before. Make sure all support legs are level before tightening the screws completely.
Page 10
13.) Connect the cable/belt track guide sections (brown and gray) to the legs of the machine using the 5/32” allen head screws from the parts box. NOTE: The section with the large hole and grommet located on it must be placed nearest the front of the machine above the middle leg (yellow).
Page 11
14.) Affix the part catcher and beak (purple) to the head of the machine using the 9/16” bolts (x4) located in the misc parts box.
Page 12
15.) Retrieve the support leg for the beak (pink) and connect the leveling feet first. Then, unscrew the 3/16” allen head screws and set them aside before maneuvering the support leg (pink) into position under the beak (purple).
Page 13
16.) Connect the beak to the support leg using the 3/16” allen head screws and spacers provided. Make sure to level the feet before tightening all bolts and screws down. 17.) Using a bubble or digital level, make adjustments to each of the section's leveling feet to ensure that the machine is lined up correctly.

18.) Remove the shrink wrap on the white X-drive belt and unroll it to the end of the machine. Make sure the belt doesn't twist and that it rides properly on top of the X-drive pulley. 19.) Feed the 2 pins on the clamp block into the holes at the rear of the machine. Tighten the entire drive belt by attaching and turning the rear 3/4”...

20.) Using the belt tension gauge from the misc parts box, proceed to take a reading of the belt's tension. This should be roughly 140 ft/lbs. Follow the instructions at this video link to ensure that you use this tool correctly. https://youtu.be/0DZYfYFccAM Tighten or loosen the 3/4”...

21.) Remove the zip ties and unwrap the cable track. Roll the end of the track under itself and run the end of the cables into the grommet halfway down the rail as shown here. 22.) Affix the end of the cable track to the track guide by clipping it into place.
Page 17
23.) Using the loops and accompanying instructions for placement in the misc parts box, connect the cabling underneath the track guide to lead the cabling toward the control box. 24.) Connect the wiring to the control box ports according to their assigned placement. Also retrieve your compressor's air hose and connect it onto the air solenoid on the control box at this time.
Page 18
25.) Connect the power, ethernet and torch cable to the ports provided in the control box. (These cables will be packaged separately inside the misc parts box). 26.) Retrieve the chuck cover from it's shipping box along with the 1/8 inch bolts (x36) for use in assembling it together.
Page 19
27.) Attach the front plate to the chuck housing with 10 of the bolts, then attach the grommet to the top of the housing base. 28.) Locate the emergency stop button from the chuck trolley and disassemble is as shown. This will be re-assembled on top of the chuck housing base.
Page 20
29.) Place the half-completed chuck housing onto the chuck trolley and affix a few 1/8 bolts to the base to keep it steady. There are 16 bolts for the base in total. 30.) Reach into the back of the chuck housing to place the e-stop switch into it's assigned hole. Make sure that the wire is routed so it won't come in contact with any gearing inside the chuck housing and that the wires on the E-stop are connected securely before you re-assemble it.
Page 21
31.) Finally affix the rear plate to the chuck housing and use the remainder of the 1/8 bolts to assemble it to the rest of the chuck trolley 32.) Remove any zip ties around the machine that might inhibit its movement. Zip ties with a tail are considered shipping ties and should be removed.
Page 22
33.) Install your Hypertherm torch and connect the torch barrel plug to the torch power supply, and to the control box (labeled Torch). Also make sure to connect your air hose to the power supply and ensure that you have at least 110-120 PSI feeding to it. This value may change depending on your torch specifications.
Page 23
34.) The airline coming from your compressor will require a splitter so that one airline is fed to the plasma power source and one is fed to the Dragon's control box as shown below. NOTE: For machines prior to serial number 210081 (found on the stamp at the tail of your machine), the user will need a third airline fed directly to the lifter station.
Page 24
35.) Install the torch sparks shield on the head of the machine using the 3/16” allen head screws provided. NOTE: You will not have a sparks shield on machines after serial number 210055. 36.) Place slug shoot (or water tray based on personal preference) in the holder below the tool head attached to the beak.
Page 25
37.) Ensure that your plasma torch power source alligator clamp is connected to the grounding wire from the Dragon machine. Be sure not to alter this connection configuration in any way. 38.) Lastly, The mounting brackets available for the machine can be used to mount the machine to the shop floor as an option.

Modifying and Installing your Hypertherm Torch For Hypertherm: 45 Amp If your Hypertherm 45 torch is brand new or unaltered, there are a few adjustments that must be made to the torch itself in order to install it onto the Dragon machine's tool head.
Page 27
For Hypertherm: 65 Amp Installing and modifying your 65 amp torch is slightly different than with the 45 amp. Follow the steps below in order to install the 65 amp torch onto your Dragon machine. Step 1: Remove the red rubber cap at the head (if attached) and use a phillips head screwdriver to remove the 3 screws accessible from the head of the torch.
Page 28
Step 5: Reassemble the torch in the order it was taken apart (minus the brass teeth), and make sure to line up the pin inside of the torch with the first ceramic section that was removed. Step 6: Tighten up all of the parts by screwing on the rear clasp last, then return the 3 phillips head screws to their original positions at the head of the torch.
