I love my oxygen concentrator. I have been using one of the larger
concentrators for all of my jewelry work for over 15 years. I
haven’t purchased oxygen in over 15 years and I never run out of
oxygen. I run both my little torch and my casting torch at he same
time and have no issues.
The EX-5 will run the little torch or something like the MECO midget
or even the Swiss torch which can do casting for smaller amounts of
metal. It will not be able to run the multi-orifice tip or one of
the larger casting torches.
Larger castings with larger amounts of metal, will require volume
and slightly higher pressure than the EX-5 can handle. We can
special order the EX-10.
