Draining water tip
The compressed gas should meet the requirement mentioned in point “Plasma gas
conditions”. Connect the gas pipe with the gas inlet of air filter on the back panel and hoop it
tightly.
The usage of air filter regulator is as follows. When it is to adjust pressure, lift up air
pressure regulating valve, and rotate it. Left rotation aims to reduce outlet gas pressure, right
rotation aims to increase outlet gas pressure. After the gas pressure is adjusted properly, press
down regulating valve.
The air filter regulator should be checked periodically. If the water level reaches two-thirds
of filter glass, it must be drained, or this will affect incision quality. The gas supply valve
should be closed during water draining, and Gas Checking function is selected in panel. When
the indicated valve of gas pressure meter is zero, water will drain out from drainage mouth
automatically.

Connection of cooling water (LGK-100 does not have this function)
Connect the copper nozzle marked with “water inlet” on the cutter back side with water
supply pipe, and tighten it. Connect the copper nozzle marked with “Backwater” with water
recycle pipe, and tighten it.
Notes:
when apply gas cooling torch, the torch selection switch on panel must be set to air-cooled
torch position, and the cooling water cannot be connected with. The cooling water is for cooling
torch only, and cutter power source does not need water cooling.
