ESAB CUTMASTER 120
Installing Optional Two - Stage Air Filter Kit
This optional two - stage air line filter is also for use on compressed air shop systems. Filter removes moisture and contaminants to at
least 5 microns.

1. Attach the Two Stage Filter bracket to the back of the power supply per instructions supplied with the filter assembly.

For a secure seal, apply thread sealant to the fitting threads according to manufacturer's instructions. Do
Not use Teflon tape as a thread sealer as small particles of the tape may break off and block the small air
passages in the torch.
2. Connect the two stage filter outlet hose to the inlet port of the Regulator / Filter Assembly.
3. Use customer - supplied fittings to connect the air line to the Filter. A 1/4 NPT to 1/4" hose barbed fitting is shown as an example.

1. Refer to the manufacturer's specifications for installation and maintenance procedures for high pressure regulators.
2. Examine the cylinder valves to be sure they are clean and free of oil, grease or any foreign material. Briefly open each cylinder
valve to blow out any dust which may be present.
3. The cylinder must be equipped with an adjustable high - pressure regulator capable of outlet pressures up to 100 psi (6.9 bar)
maximum and flows of at least 300 scfh (141.5 lpm).
4. Connect supply hose to the cylinder.
NOTE!
Pressure should be set at 100 psi (6.9 bar) at the high pressure cylinder regulator.

passages in the torch.
