Does anyone have any experience with 'Browns Gas' cutting (dissociated
H2 and 02 atomic mix, or something like that, I'm not sure),
sometimes known as 'water torch'? (its NOT abrasive water jet cutting).

For example

and

and I think there is a European hand-held torch for about US$600, but I've
lost the link.

Somehow, the claim is that it cuts 'cold', and is good for cutting
iron/steel/cast iron, welding and fusing various metals.

Now I don't know anything about this, they further claim 10-25%% faster
cutting than plasma, with a narrower jet (and thus allows for greater
distance (hence greater distance tolerance) from the work, and/or deeper cutting).

What interests me is that (unlike plasma, where the expensive tip is 'used up'
after 100+ starts), and thus its life is limited by the number of starts not the
distance cut (as I understand it), the BG cutter does not seem to require any
consumables (other than oxygen) and thus would work great for a bunch of start/stop
intermittant cutting.

Anyone have any experience with it?
