Hi there, first post!
I rent argon and nitrogen for welding and chemistry experiments. I had to sell the TIG set to raise some money, so it's mainly chemistry at the moment. The gases are used, as per with welding, to blanket experiments that are sensitive to moisture or oxygen in the atmosphere.
I took some photos, but now can't get the card reader to work.
I've been using one of those cheap, all brass, comes with the set, single stage SWP regulators.
Even when it was working normally, it wasn't all that nice. But now some of the corrosive gases in the atmosphere appear to have corroded the spring / nut / diaphragm and the thing is refusing to behave in a stable manner.
To get any flow out of it, I'll have to wind the handle in too far. It suddenly jumps to an output pressure of tens of PSI. Trying to back it off, it will usually close it's self.
This is not only rendering it fairly useless in terms of functioning as a control, it's of coarse a worrying sign that it could fail.
I have since acquired an Air Product E12-244B, which is a much more substantial two stage with chrome plating and a flow control. It's previous owner was using it on chlorine and hydrogen sulphide cylinders.
The problem being, it has a side entry port and a CGA 590 fitting, so it won't fit inert cylinders.
Does anyone here have experience or knowledge with regards to swapping the fittings? The burst disc is on the base on the regulator.
All the best!
