[Precations for flow switch]
Water pressure:
This machine uses a flow rate switch to prevent the water-cooled torch from burning. For the
flow rate switch, since the water amount becomes small in a low water pressure place, "WARN."
indicator lamp lights up, and it ceases to operate. In this case, be sure to take in water
from a high water pressure place or locat a water tank (YX-09KBA1). Also, always keep the water
0.12Mpa
pressure at
1.2kgf/cm
* When using the water tank:
Replace cooling water with a new one 1 or 2 times per 6 months. Deposited fur may cause the
pump motor to rortate, and the water line of torch and flow rate switch may become clogged
accordingly.
When using non-freezing fluid:
For non-freezing fluid, always use glycols. If this antifreeze mixing ratio is increased, cooling
water viscosity becomes higher, this making it hard to let cooling water flow, and the flow
rate switch may become inoperative. therefore, it is recommended that this antifreeze mixing
ratio should not exceed 20%.
