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.
