I’m planning on hooking my Little Torch into my main service (big
outside tank, black pipe = high pressure line running into the
workshop). My guys needed to know the technical specs on the torch
so they could hook it in properly (required pressure, adapter type,
whatever) which I didn’t know so I called Rio Grande, thinking I
would be able to get a spec sheet mailed to me.
Instead the guy at Rio Grande acted like I was brain damaged to even
ask, said he’d never even heard of trying to do such a thing (you
guys have, haven’t you? Seems I’ve seen postings about this in old
archives). I wasn’t sure enough of what the guys wanted to really
even know what to ask. He finally ended up telling me the little
torch needed 15 lbs of pressure (sounds pretty high for a small
torch, seemed to me) and had no idea about adapters. He was even
sort of surly about it. I DID manage to wangle the 800 number for
Smith out of him, though, luckily.
The guy at SMITH said the max pressure a little torch would ever
need is TEN (not fifteen) lbs and gave me the name of the connector
on the regulator that comes with it so that the guys would know what
adapter they needed. In fact he sort of choked when I told him what
Rio Grande had told me, so I guess I’m glad I called them.
I would say I trust the manufacturer more than a surly Rio Grande
employee so I guess that’s the info I’ll pass on to my guys. I will
say that this is the first and only time Rio Grande personell have
been, shall we say, less than helpful. As far as I can figure, I’m
going to require two regulators from my main tank, one to step down
tank pressure to the 1/2 lb that household appliances use and one to
step it down to the 10 lbs the Little Torch apparently needs (then
the actual torch regulator after that). Hopefully the guys are
going to be more certain of this than I am.
I’d like to hear from anyone else currently running a O2 little
torch of their main supply tank in case there’s anything else about
doing it this way that I should know (and I will have the flashback
Also any info about storage of O2 tanks would be good - like safe
temp ranges. I do know they need to be battened down (fastened
securely in an upright position) so they don’t fall over and turn
into a missile. Other than that I don’t know much about the O2 or
where to place it.
