NOTE
Argon must be used for the “Marking” gas. If replacing existing fittings in the base, 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.
NOTE
If you need to replace a gas or water fitting all inlets and outlets of the aluminum manifold are 1/4” NPT
(United States National Pipe Thread) into which are screwed the various adapters.
