Look into the regulators sold with/for the Dillon/Cobra/Henrob 2000/DHC 2000 torch (it has gone through a few names as different companies has sold them through the years, DHC 2000 being the current unless I'm mistaken). It runs 4psi on both gases.

 

Using my Smith Little Torch with Purox regulators isn’t exactly ideal,
requiring some readjustment. I notice regulators are available for the
Little Torch (from Guesswein and probably others) and assume they’re
better suited to the low pressure requirements of the small torches. I
personally would rather deal with the readjustment than buy, store and
deal with another set of regulators.
I wonder if the problem is more in the gauge than the regulator, and
maybe using gauges with less span would make adjusting for the
Little Torch easier, while still providing enough oxygen pressure to allow
me to use the cutting torch.

 

Go over to tinman com(Kent White) and see what he uses these decades.

I think its two things: first a lot of the regulators that come with torch sets are single stage, meaning as the pressure in the gas cylinder drops, you need to readjust the pressure delivered to the torch. If you want to avoid that, you need a two stage regulator. However for most torch uses this is not really needed. You may be able to get by just replacing the low pressure gauge with something like this if you don't use the regulator for oxyfuel cutting. https://store.mathesongas.com/very-low-pressure-gauge-brass/

 

My low press. oxygen gauge is 0-200 psi. If I remember
correctly, the Little Torch is looking for ~1 or 2 psi.
A 0-50 oxygen gauge would still allow me to cut, and I think
it would be an improvement when using the Little Torch.
My current procedure for setting the oxygen pressure for the
Little Torch is to get the needle just off the stop pin at 0.

 

Thanks all for your input ! I think I will try changing out the gauge first. I looked at the link those are VERY low pressure gauges indeed - then I found this puppy
https://store.mathesongas.com/low-pressure-large-dial-gauge-brass/ but I have yet to read all the fine print to see if it is compatable. I will also check out what Detroit Torch offers.

Thanks againn.

Are your regulators the Victor edge ? Those gauges are regulator specific I believe.

 

Smith 30 series ? A little pricey but guaranteed to be +/ - 2 % of gauge reading !

 

Now your talking. Was thinking to suggest the same a while ago. Didn't want to bust the budget.

Drink the Blue Coolaid baby.

Don't buy just the regulators as they cost nearly as much as a whole kit right now with the $40 off the set with the NON-Lifetime torches. They are like $260 minus $40 rebate. $220 is a deal. Sell everything else but regulators for $120 and you got your 30 series regulators for $50 a piece. You can't hardly buy Harbor Fright crap for that.

Even better $250 minus the $40. https://store.cyberweld.com/smith-toughcut-welding-outfit-mb54a-510.html
