An optional filter kit is recommended for improved filtering with compressed air, to keep moisture and debris out of
the torch.
1. Attach the Single - Stage Filter Hose to the Inlet Port.
2. Attach the Filter Assembly to the filter hose.
3. Connect the gas line to the Filter. The illustration shows typical fittings as an example. Other fittings may be
used.
NOTE
For a secure seal, apply thread sealant to the fitting threads, according to the maker's instructions. Do Not use
Teflon tape as a thread sealer, as small particles of the tape may break off and block the small gas passages in the torch.

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 gas supply hose to the cylinder.
NOTE
Pressure should be set at 100 psi (6.9 bar) at the high pressure gas cylinder regulator.
Supply hose must be at least 1/4 inch (6 mm) I.D.
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 gas passages in the torch.
