yes, my dear, a few things are different in italy.
the acetilene, propane and oxygen regulator and tank fittings
are all different from the standard used in the us and you need
to acquire the proper ones to make sure that (a) they fit the
tank and/or torch you have so you can work and (b) they are of
professional quality so you don’t blow yourself up… regulators
also need to be checked.
you might need to find a better dealer (believe me there are,
all types, smokers and not) or you might need to test the italian
gears and get a feel for it.
all i can provide you from here is the harris calorific-italy
