I have come across a couple of two stage Victor regs that I would like
to use on an OA torch setup. The question I have is that according to
what I can find on the web and simply by looking at the two regs one is
a medium duty and the other is a heavy duty. The 3s are VTS410A(Fuel)
and VTS250A(Oxy). The acetylene reg is huge! Can these be used together
on the same outfit? I know they may look a little imbalanced but
function is what I'm after.
Two stage regulators are great. I don't know of any reason you can't use a big
one on one cylinder and a medium sized on another cylinder. Who cares about
cosmetics? What matters is at the other end, what you're cutting or welding!
I have a pair of VTS-450s and I love 'em. I tend to only use them for torch
cutting, where precise control of pressure is critical. Sometimes regulators
come around and sometimes they're scarce. Lately around here they've been
bountiful, and I seem to have 4 pairs now.
The two stage, heavy duty regulators are preferred over single stage
regulators. The big reason is that if you use a substantial portion of a
tank in one session, the output pressure on the two stage varies less
than the single stage versions.
That said, I'm not sure I'd reccomend a used heavy duty 2 stage
regulator over a NEW single stage unit. 2 stage units are always used in
a commercial or industrial setting. Read: hard use, likely to have
"issues". My benchmark for new units is a genuine Victor brand jounyman
single stage outfit for $170 to $200. These are great for a casual or
hobbist user and you know they will not give you any grief. A leaky
regulator can be a pain or dangerous, runs $45 to $60 for a rebuild.
I have a spare used Harris set that was given to me on the condition
that I NOT use it without a through rework. The owner just didn't want
to deal with the old stuff. Haven't done anyting with it yet, expect
that at least one of the regulators will need a rebuild on my "free" set.
