Where does the name "forming gas" come from?--Srleffler 17:37, 1 June 2007 (UTC)

It is a bit odd that it says it can be found at welding supply stores but has no obvious reference (annealing?) as to why it would be used in welding —Preceding unsigned comment added by 63.250.137.14 (talk) 18:51, 29 January 2008 (UTC)

No mention of what threshold for explosion hazard? — Preceding unsigned comment added by 128.84.182.179 (talk) 16:00, 10 August 2011 (UTC)

If you know/can look up the threshold and have a good reference for it, please add that information to the article! -- Avocado (talk) 17:23, 10 August 2011 (UTC)

Sentence is unclear

This sentence "The lower explosion limit for 100% hydrogen is < 4% and for forming gas 5,6% at room temperature." is unclear. It's probably talking about adding forming gas to something (air?) that contains oxygen. And what does it mean to say "100% hydrogen is < 4%"? -- Dough34 (talk) 17:59, 20 October 2013 (UTC)
