I use an air/acetylene setup for soldering. Lately I've been getting a purplish tinge on my hands and tips.
I've been told it could be a leak in the hose or somewhere else which I havn't checked yet.
But upon further investigation I found there is this thing called drawdown where acetone can actually be pulled from the cylinder and may cause this. Anybody familiar with this phenomena. I've heard that you can only draw about 1/7 per hour the tank capacity before acetone starts being draw out.
For an MC tank which is 10 SCF. Does this mean I can draw 1.4 SCFH at a constant rate or can I draw the 1.4 SCF at once and wait an hour for the tank to recover? So I guess what I'm asking is can I go with a higher flow rate as long as it averages out to 1.4 SCFH.
