I’m using a O2 concentrator with butane for many years now with no
The only backdraft I experience is the little amount of material I
can melt compared with my Oxy/Acety configuration.
Melting about 100gr of metal (mostly Ag or Au) is a piece of cake
with Oxy/Acety Compared with the concentrator configuraion, I’m
reduced to a max of 30gr by adding slowly new material to the melt.
Melting that amount of material in one batch is out of the question.
I concidered to buy an adjustable Oxy booster in order to have more
O2 pressure is no option to me.
Other then that, I’m happy with my O2-concentrator.
Still, I wonder how others solved the low pressure issue with with
their O2-concentrator configuration.
