I know that those sintering furnaces for metal-binder printers use an argon-hydrogen mix, 2.9% hydrogen. Not sure how safe it'd be in this application, but I think may work.

Welcome to the forum tedlasman.

I have heard of hydrogen being used in welding to help increase the level of heat but never in this context. I'm not sure how comfortable I would be testing that theory out.
