SECTION 4. COMPANY PROFILE
Manufacturer since 1973 Ajan Elektronik, established in 1973, started its life by manufacturing uninterruptable power supply
systems. The firm decided to manufacture Electrical Discharge Machines and released the first
machine in 1975 to the market.
In early years due to the conditions of the day, the company manufactured hydraulic machines, but
today the company switched to AC servo controlled machines.
Ajan Elektronik started to work on CNC projects in 198889, and manufactured the first CNC
Erosion Machine in 2000. Continuing working on this subject in R&D department, the company
developed and manufactured CNC Milling Machines, CNC Lathes, CNC Plasma and Oxy-Fuel
Cutting Machines, CNC Drilling Machines and CNC Laser Cutting Machines.
All the CNC control units and software, servo drives and AC servo motors of the manufactured
machines are completely own production of the company.
Ajan Elektronik provides AjanCAD Ajan Drawing software free of charge with the manufactured
machines to the customers.
The company supplies 85% of the raw and intermediary materials used in manufacturing of the
machines, whose design is completely done by itself, from the domestic market. Hence, the
company supports the economy of the country.
In addition, Ajan Elektronik began many new projects according to the customer demands.
As a result of giving importance to quality, the company has won ISO 9001:2000 Quality
Certificate on June 24th 2003.

5.4. MAIN POWER
The grounding must take place at the main power.
The main power of the machine must be connected in accordance to the manufacturers directives.
If any interference or undulation at the current occurs, a filter (regulator) can be added to the main
power or the supply cable can be shielded. In addition, it is advised that the electrical supply cable
must be in length of maximum 5 meters and the temperature of the ambiance must not extend 40C.
Under the case of that the allowed temperature is extended, the cutting current should be reduced. It

6.10. WELDING FUMES AND GASES
Welding fumes are an unavoidable by-product of the welding and cutting process. All these
processes generate fumes, only the type and amount vary from process to process. It consists of
particulate fume, the part you can see, and gaseous fume, the part you cannot see, but can
sometimes smell.
Exposure of welders to welding fumes depends on many factors: the most important of which is
actual type of welding is being done.
For example, FCAW, MMA, MIG, thermic lancing and plasma cutting tend to produce the highest
amounts of most particulate fumes, while TIG, plasma welding, oxy-fuel welding, laser welding,
laser cutting and submerged arc normally give very little.
TIG, plasma welding, MIG, laser cutting and welding tend to produce the most gaseous fumes
while MMA, plasma cutting and FCAW normally produce very little.
The potential effect of exposure to welding or cutting fumes depends on the composition of the
fumes.
The health effects of exposure to fumes include irritation of the upper respiratory tract (nose and
throat), tightness in the chest, wheezing, metal fume fever, lung damage, bronchitis or pneumonia,
possibly even cancer or emphysema.
Possible control measures include doing things such as changing or modifying the process, or the
way the job is done.
6.10.1. FUMES AND GASES
The nature of fume depends upon the metal being cut and upon any coating. Cutting of stainless
steel is potentially the most hazardous as the fumes will contain chromium and nickel. Copper and
its alloys are also commonly cut and can also produce a significant fume hazard. The risks from
fumes should be assessed in accordance with HSE Guidance Note EH54 Assessments of exposure to
fume from welding and allied processes.
Oxides of nitrogen are formed during plasma cutting and could accumulate in areas of poor
ventilation. These are likely to be most significant during plasma cutting where air or nitrogen is
used as the plasma gas. Ozone is most likely to be formed during cutting of aluminum or stainless
steel.
Where inert gases are used they may accumulate in contained spaces causing an asphyxiation risk.
This is most likely to occur when the gas is significantly heavier than air e.g. argon/nitrogen
mixtures.
In poorly ventilated areas, flammable gases may also produce a risk.
Gases, particularly oxides of nitrogen, are a more significant hazard at hand-held cutting than at
mechanized cutting as the operator is in close proximity to the torch.
MAINTENANCE MANUAL FOR AJAN PRECISION PLASMA CUTTING MACHINES
SAFETY
13
6.10.2. TOXIC FUMES AND GASES
Plasma arc cutting can produce toxic fumes and gases that deplete oxygen and cause serious injury.
Keep the cutting area well ventilated or use an approved air-supplied respirator.
Do not cut in locations near degreasing, cleaning or spraying operations. The vapors from certain chlorinated solvents decompose to form phosgene gas when exposed to ultraviolet
radiation.
6.10.3. LOW-TEMPERATURE PLASMA FUMES, EXHAUST GAS PURIFICATION FOR ORGANIC
On principle, the purification device uses corona current and high power pulse discharge principle,
so that the air around the plate becomes a low-temperature plasma.
Plasma with many high-energy (OH-, O2-, H+, O3) ions are surrounding the plate, with energy of
the plasma can interrupt a variety of organic molecules of gas between the key elements so that the
decomposition of harmful gases to the fumes, formaldehyde, xylene, sulfur dioxide, ammonia
nitrogen oxides and other harmful gases and odor generated degradation and oxidation, deal with
organic material and degradation of smell effectively. In addition the purification equipment
compared with electrostatic precipitator, low power consumption, more efficient purification, and
so on.

11.1. VENTILATION UNIT
They are the systems sucking and removing the dangerous gases and dust occurring during the
plasma cutting application away from the medium. As the working principle, the air suction occurs
when the pressure handles on the working area are opened by pressure sheet on the machines
bridge unit, and it sucks the dust and gas in the cutting area. The sheet to be cut is placed on the grid
blocks. After the cutting process, the dross and some cutting wastes are collected in the cutting
buckets. For a long life and proper operation of the ventilation unit, it should be frequently cleaned
depending on the fullness ratio.

Figure 17. Total area of the cartridges used in the jet filter
The jet filter is manufactured in 4 different models, such as 6-, 8-, 12- and 16-cardridge, depending
on the ventilation capacity required for the machine. Every cartridge is made up from 24 meter
square burn-delayed plied filter paper.
System dirt level is controlled by electronic filter cleaning unit. With the help of blow level control,
the blow frequency is decreased, cycle is increased. So unnecessary air consumption is prevented.
30% more efficient reverse jet filter cleaning air flows are obtained by dust bag shaker valves
integrated on the filter body. Because of that the cartridges are horizontally mounted, the
maintenance and replacement are easily done. Jet filter unit is additionally preserved with flame
trap that should take place in every plasma cutting table ventilation.
Flame trap holds cigarette butt, burning paper sheets and cloth parts and moves them to the buck it
has.
Ajan jet filter system is a genuine design completely suitable to the world standards. The air suction
fan is mounted outside of the filter and it is suitable for cleansing after long-time usage. The motor
and propeller are equipped with an easily opened and closed cover system.
The complete filter system is transported by demounted during the transportation. The air suction
system has been designed to be fit in any smallest area behind the plasma ventilation table. During
the filter design, space occupation is kept in mind in height in spite of width or length. A muffler
with two walls is mounted on the fan output. The muffler output can be mounted outside of the
building by the customer.

transported in the generator with the machine. A mixture of 30% Propileneglicol (C3H8O2), 69.9%
deionized water and 0.1% Benzotriazole (C6H5N3) is suggested for Ajan cooling liquid. This
mixture prevents freezing up to 12C.
Warning: The operations in colder than the above indicated degree, the propileneglicol ratio should
be increased. For the required ratios and material supply, please contact the manufacturer company.
WARNING
Figure 30. Torch cooling liquid drum warning label
The cooling liquid may cause skin and eye irritation, and if swallowed, it may be harmful or fatal.
Propileneglicol and benzotriazole may harm skin and eyes. Please keep the labels on the drums. In
any contact, wash the skin or eyes. If swallowed, drink water and call the doctor. Do not try to
regurgitate.
Warning: Use always propileneglicol in the mixture of cooling liquid. Do not use automotive
antifreeze liquids in spite of propileneglicol.
Use always pure water in the mixture of cooling water in order to prevent failures that may occur in
the pump and oxidation in torch cooling system.
