I personally like the Smith torch setup for acetylene. Goes on a "B"
tank (40 cubic ft), uses ambient air, so no oxygen tank. Prestolite
is another good manufacturer, though I’m not fond of their torch
You need the tank (it arrives empty), fittings specifically for that
tank, regulator, hose, torch handle and torch head. Rather than
buying the individual pieces, you can buy it as a kit. I find the
included torch head for the Smith is a size 00, way too small. I
commonly use a size 0 and a 3.
Spring for one of the electric spark units rather than the manual
torch lighter. It will make your life so much better. But it never
hurts to know how to use the manual one.
I used a setup like this for several years in my spare bedroom (aka
workshop) until I moved into a commercial storefront. Just use the
same safety procedures you would use in a workshop (ventilation,
tank mounted upright, torch safety) and you will fine at home.
