1. GENERAL INFORMATION
1.1. Application
The DRAGON (HS) is acutting carriage designed to cut steel by using oxy-fuel or
plasma torches with the handle diameter of 28–35 mm (1.10–1.38’’). The carriage
travels horizontally on the workpiece or track with the inclination of up to 10°.
Accessories allow, for example, using torches with different handle diameters,
using two torches simultaneously, and cutting holes with the radius of 240–2500 mm
(0.8–8.2 ft).

2. SAFETY PRECAUTIONS
1. Before beginning, read this Operator’s Manual and complete proper occupational
safety and health training.
2. Use the carriage only in applications specified in this Operator’s Manual.
3. The carriage must be complete and all parts must be genuine and fully operational.
4. The specifications of the power source must conform to those specified on the
rating plate.
5. Plug the carriage into a properly grounded power source.
6. Never carry the carriage by the cords or the arc ignition cable and never pull them
as this may damage them and result in electric shock.
7. Untrained bystanders must not be present near the carriage.
8. Before beginning, make sure that the correct is the condition of the carriage,
power source, power cords, arc ignition cable, plugs, and control panel.
9. Keep the carriage dry. Exposure to rain, snow, or frost is prohibited.
10. Keep the work area well lit, clean, and free of obstacles.
11. Never use near flammable liquids or gases, or in explosive environments.
12. Transport and position the carriage by using the carrying handle.
13. Do not stay below the carriage placed at heights.
14. Plug the cords and arc ignition cable into sockets only when the power switch is
set to the position ‘O’.
15. Keep the sockets clean. Do not use compressed air for cleaning.
16. Install only torches whose handle diameter corresponds to the torch holder in use.
17. Keep the torch cables from coming in contact with the surface. They must be
suspended to reduce the load of the carriage.
18. Operate the torch according to the torch manual.
19. The carriage must be positioned in the horizontal position during operation.
20. Always use eye protection (helmet, shield, and screen), hearing protection,
gloves, and protective clothing during operation. Do not wear loose clothing.
21. Before every use, inspect the carriage to ensure it is not damaged. Check whether
any part is cracked or improperly fitted. Make sure to maintain proper conditions
that may affect the operation of the carriage.
22. Never try to manually stop the motion of the carriage. To stop, set the clutch to
OFF or the travel direction switch to the position ‘O’.

23. Maintain only when the carriage is unplugged from the power source.
24. Repair only in a service center appointed by the seller.
25. If the carriage falls from any height, is wet, or has any other damage that could
affect the technical state of the carriage, stop the operation and immediately
send the carriage to the service center for inspection and repair.
26. Never leave the carriage unattended during operation.
27. Remove from the worksite and store in a secure and dry location when not in use.

3. STARTUP AND OPERATION
3.1. Preparing
Before beginning, clean the wheels of the carriage and remove the anti-corrosion
coating from the track. Use the carrying handle to transport the carriage to the
worksite. Set the power switch and the travel direction switch to the position ‘O’, and
set the clutch to the position OFF. Then, plug the power cord into the power source,
insert the torch into the standard torch holder (Fig. 2), and secure with the knobs.
Fig. 2. Standard torch holder design
The holder allows torches with the handle diameter of 28–35 mm (1.10–1.38’’).
Loosen the lower handle to roughly set the torch angle.
Use the rack position knob to adjust the horizontal position of the torch, and use
the rack locking levers to lock the rack in position.
Then, connect the torch to a proper gas source. Depending on the cutting method
(oxy-fuel or plasma) install into the carriage slot either a gas manifold or the arc
ignition set in the manner described in the subsection of the respective accessory.
Position the carriage on the workpiece or the track so that the torch is placed
right above the starting point of the cut. Then, set the clutch to the position ON.

3.2. Operating
Turn on the power by setting the power switch to the position ‘I’, which will illuminate
all segments of the display ( ). After a while, the indication will change to if
the unit of speed is set to centimeters per minute, or to for inches per minute.
Then, the carriage speed will appear, which can be adjusted by rotating the knob
located on the panel. If needed, travel the carriage manually after setting the clutch to
the position OFF.
To begin the cutting process, light the torch in the manner described in the torch
manual. Adhere to all rules included in the torch manual.
Select a direction of motion with the travel direction switch, and then the real
speed of the carriage will appear on the display. To stop the motion, set the travel
direction switch to position ‘O’or the clutch to position OFF. To extinguish the torch
flame, proceed according to the torch manual.
After the work is finished, turn off the power with the power switch and unplug the
carriage from the power source. Clean the teeth of the rack once aweek.
3.3. Changing the unit of speed
To change the unit of speed from inches per minute to centimeters per minute or vice
versa, unplug the carriage from the power source and follow the steps shown in Fig. 3.
After changing the unit and powering the carriage again, the actual unit of measure
will appear. With the jumper cap connecting the left and center pin, the display shows
and the speed is given in centimeters per minute. With the jumper cap
connecting the center and right pin, the display shows message and the speed
is indicated in inches per minute. The 2.5 mm hex wrench needed to unscrew the
control panel is not included in standard equipment.
