• The device turns into protection mode if the power supply tension is below or above the 15%. To indicate this default, the screen displays an error
code.
• In order to ensure optimal functioning of the equipment, check that the compressed air circuit can supply 8 bar (116 Psi) and then connect the air
supply to the back of the machine. The machine must not be used on an air network with a pressure under 4 bar (58 Psi) or over 10 bar (145 Psi).
CONNECTION TO A GENERATOR
The equipment is not protected against the regular overvoltage waves emitted by the power generator. It is therefore not recommended to connect
them on this type of power supply.
USE OF EXTENSION LEADS
All extension cables must have an adequate size and section, relative to the voltage of the machine. Use an extension lead that complies with national
safety regulations.
REFILL OF THE COOLING LIQUID TANK
The cooling liquid CORAGARD CS330 (or equivalent), recommended by CHIEF, must be used.
(more information is available on the website : http://www.aqua-concept-gmbh.eu)
The use of any other coolant (in particular the automotive standard coolant), can lead, by electrolysis effect, to the accumulation of solid deposits in
the cooling system, thus damaging it and also blocking the circuit. Any damage caused to the machine by the use of another cooling liquid will not
be taken under warranty.
The liquid CORAGARD CS330 when used purely provide a protection against freezing for temperatures down to -20°C (-4°F). It can be diluted, but
only by using deionised water and never tap water! In any case, a minimum of 10 litres must be used to protect the cooling circuit.
30 litres (8 US Gal) of CS330
20 litres (5 US Gal) of CS330 + 10 litres (3 US Gal) of deionised water
10 litres (3 US Gal) of CS330 + 20 litres (5 US Gal) of deionised water
Any damage resulting from frost will not be covered by the warranty.
To refill the cooling liquid tank, proceed as follows :
- Put the pneumatic clamp on its support.
- Pour 30 litres of liquid to reach half of the level indicated.
Safety data concerning the liquid CS330 :
- in case of contact with eyes, remove contact lenses if worn and rinse thoroughly using clear water for several minutes. Seek medical
advice if complications occur.
- in case of contact with the skin, clean thoroughly using soap and remove any contaminated clothing immediately. Seek medical
advice if the skin gets irritated.
- in case of the liquid being swallowed, rinse the mouth abundantly using clear water. Drink plenty of water. Seek medical advice.
Maintenance : See chapter «PRECAUTIONS AND MAINTENANCE».
STARTING THE MACHINE
• Start the machine by switching the circuit breaker on ON (Fig 1 - 7), and stop it by switching to OFF. Warning! Never disconnect the power
supply when the welding electrical distribution is in operation. The PCB inside the machine starts a test cycle and initiate the settings which
takes around 10 seconds. At the end of that cycle, the machine is ready to be used.
• As soon as the machine is powered, the liquid starts circulating in the cables. check for potential leaks.
