A. Connecting Gas Supply to Unit
The connection is the same for compressed air or high pressure gas cylinders. Refer to subsection 3.4-C if an optional
air line filter is to be installed.
1. Connect the gas line to the inlet port. The illustration shows typical fittings as an example.
NOTE
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.
