Problem with Oxygen / Acetylene Cutting Torch >> Acetylene line clogged

If its got built in flashback arrestors, they could be blocked with dust.
I dunno if the stuff that's in the acetylene tank can get right up into the torch, its a lint like material.



Honestly, the gas companys are pretty loose reguarding their practises.
I heard one idiot say "we get free acetone by, when we have emptyed the acetylene bottle, we turn it upside down and drain out a few litres of acetone......". Duh! The guy worked at a paint and panel car fixers.
