The input gas must fit for the system gas supply requirements, if use high press gas cylinder supply gas, must choose
good quality gas regulator to ensure the gas pressure stable
When adopt O

as the plasma gas, there is risk for fire, so exhaust ventilation system must be installed, after
installation, must check if there is any leak

11. Filling coolant liquid
Improper coolant will cause damage for the machine
Please refer to the coolant requirements
Coolant capacity of the cooling system is 20 liters, the specific capacity depends on the length of the integrated cable.
Firstly, pour coolant into power until the bucket is filled. Power indicator of cutting power panel and liquid level
indicator should be on; water pump in cutting power supply starts to work, then the liquid flow indicator is lit. (If the cable
length is longer (more than 50 meters), the cooling fluid level will decrease and panel liquid level indicator will be
extinguished after the pump works for a while, then the water pump stops working. In this case, please turn off the power,
fill cooling liquid into the bucket again, and turn on power supply until the coolant flow is normal, panel liquid flow indicator
is lit.
Finally, turn off the power; fill the cooling fluid into the bucket and cover bucket.
12. Setting of gas supply
Start the gas supply equipment, open the gas supply switch. Turn on the power, the pressure indicator of cutting power
panel should be lighted. If the pressure is less than 0.2Mpa, the air pressure indicator will not be lighted, need to check the
gas supply.
Place the gas control switch to "check gas" position, adjust the plasma gas and protecting gas pressure to make the
output pressure or flow satisfy cutting requirements (please see the cutting table for regulated value), after adjustment,
