Hydrogen Warning!

Hydrogen gas used as a fuel produces a very hot flame which may be invisible and should be used only with great caution and experience. (Remember the Hindenburg Airship.) Because of its fast speed of flame propagation the fuel velocity is an important factor in keeping the flame on the outside of the burner. It is recommended that a Carlisle FG-7 flashback arrestor be placed between any burner and its hydrogen fuel source.

Only unpiloted tips or surface mixed burners should be used with hydrogen on hand torches, lathe burners or bench models!
