Rob - I used street pressure ng with compressed oxygen in my studio
for 12+ years. Meco Midget with ventilated tips worked just fine. New
manufacturer of those ventilated tips is Paige Tools. They were
originally sold to glass workers. The one hole tips usually supplied
for ng are useless with street pressure ng.
The community college where I first learned metal smithing used Hoke
torches, ng and compressed air. Worked ok.
Now I used a G-tec concentrator for natural gas and like it ever so
much better. Same torch - Meco Midget - best advice I ever got was to
try the Meco Midget. It is a work horse. I do have a longer neck for
when I’m using the huge “bush burner” tips from Paige Tools,
otherwise the torch gets pretty warm.
Best price for the Meco is from the Tin Man - Tinmantech.com. Get
your tips from paige tools.
I am unaffiliated with Paige Tools, I just find that their
ventilated tips are the best ever!
