IDENTIFYING SAFETY INFORMATION



These symbols are being used to identify potential risks.
When seen a safety symbol in the manual, it must be understood that there is an injury risk and following
instructions must be read carefully to avoid potential risks.
While welding, keep the third persons and especially the children away from the work area.
UNDERSTANDING THE SAFETY WARNINGS
Read carefully the manual and the labels and the safety warnings on the machine.
Make sure that the warning labels positioned on your machine are in good order. Renew the damaged and
the missing labels.

immediate steps to improve ventilation. Do not continue welding if symptoms persist
Install a natural or forced air ventilation system in the work area
Install an adequate ventilation system in the welding and cutting area, if needed
install a system that can remove the fume and vapor accumulated in the entire work
area, to prevent pollution use adequate filtration in discharge
In the event of welding in small, confined places, or welding lead, beryllium,
cadmium, zinc, zinc coated or painted materials; also wear a fresh air supplied
respirator in addition to the above mentioned rules
Always have a trained watchperson nearby, while working in small confined places.
Avoid working in such confined places if possible
If gas cylinders are grouped in a different area, make sure that it is a well-ventilated
area. When not being used, turn off the main cylinder valve and watch out for gas
leakage
Shielding gasses such as argon is denser than air and when being used in confined
places, can be inhaled is dangerous for health

To reduce possible interference, keep weld cables as short as possible, close together, and down low, such
as on the floor
To avoid possible EMC damages, locate welding operation as far as possible (100 meters) from any
sensitive electronic equipment
Be sure this welding machine is installed and grounded according to this manual

RA300E, RA400E and RA650E are t yristor (SCR) controlled welding machines, designed to weld all type of
coated electrodes from 2mm, 300 model up to 5 mm, 400 & 650 models up to 6mm, while 400 model can
carbon gauge up to 6mm, 650 model can carbon gauge up to 10mm. For RA650E, cellulosic welding at low
currents is not recommended. Since 300 & 400 models can go as low as 20 Amps, their cellulosic welding
behavior is excellent and if a proper TIG starting unit is connected, they can perform as a DC TIG welder as
well. These units can be grouped as 4, 6, 8 or 9 machines in a rack, for large construction sites like shipbuilding
etc.
Due to th ristor (SCR) and electronic close loop control technology, current is adjusted precisely by a
potentiometer, initial striking ability of the electrodes can be improved via Hot Start potentiometer and certain
electrodes like basic electrodes which have tendency to short circuit and stick to the weld pool could be
avoided by adjusting the Arc Force potentiometer. Also due to this technology, pre-adjusted current stays
stable even during mains fluctuations or if additional welding cables are used. Electrical efficiency of these
machines are 70%.
Even though there is a certain level of electronics is involved in this machine, the PCB is protected in a
separate cabinet inside of the machine against dust and corrosion. With its telescopic arms and big wheels it
can be pulled easily across the working area especially at outdoor welding sites. Also stepless remote current
controlling is possible as an option.
These machines are fan cooled and thermally protected against overheating and phase failures.

2. INSTALLATION
2.2 INSTALLATION AND WORKING RECOMMENDATIONS
• Use lifting eyes or fork-lift to carry the machine.
Transport and place the device on a firm and level
ground so that it may not fall over. The maximum
permissible angle of inclination for transport and
assembly is 10°.
• For a better performance, keep the machine at
least 30 cm away from the surrounding objects.
Beware of excessive heat, dust and humidity
around the machine. Try not to operate the
machine under direct sunlight. Machines should
be operated on lower capacities when ambient air
temperature exceeds 40ºC.
• Avoid welding at outdoors where it is windy and
rainy, if this is a must, protect the welding area with
curtains, mobile screens or tents.
• Ensure that operators can easily reach the
machine controls and connections.
• Respect the duty cycles given at the data plate.
Exceeding the duty cycles frequently can damage
the machine and this would void the warranty.
• Do not use stronger fuses than those stated on the
data plate.
• Ensure that the earth clamp is tightly connected as
close as possible to the welding location. Do not let
welding current flow through any media other than
welding cables; e.g. over the machine itself, gas
tubes, chains, ball bearings, etc.
• Use suitable welding fume extraction systems.
Use breathing apparatus if there is a risk of inhaling
in confined places.
