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).

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.

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
