Here is conversion sheet to use.Okay, so basically the same tighness as when placed tighly around the head?
Thanks for your reply
Comment 2:
I am also using an argon regulator for a nitrogen tank. Since that was the only thing easily available. From what I understand, the LPM should be set to 21 LPM to be equal to 15 liter per minute of nitrogen (due to different densities). Some have stated 12 lpm, but that seems to be for something different from what I understan
- 12.5LPM on argon flowmeter gives ~15litres LPM nitrogen flow
- 15LPM on argon flowmeter gives ~ 18LPM nitrogen flow
- 20 LPM on argon flowmeter gives ~ 24 LPM nitrogen flow
Thanks very much for your helpful info from both of you
Although, I emailed two welding firms in Sweden about the conversion rate using argon meter for Nitrogen. Neither of them were sure what to use to get 15 lpm.
I think the best way is probably to see what the pressure is inside the bottle and then adjust the reducer until 2 bars pressure is lost per minute. Either that or waiting for the bag to fill up in 1-2 minutes time.
A gauge regulator should work the same way as a flowmeter, but there is nothing wrong with testing it with a balloon to be sure.Ah thanks for that link. I found similar info, but they never mentioned that it could be used for a flow gauge regulator. Just flowmeters.
But seems like that should work too.
Thanks, but I already got a cylinder
I'm using one with a built in regulator but I have tested mine with the flow meter. I would suggest not opening the main valve without the regulator since it would be a safety hazard and potentially wasting precious gas. Most videos I have seen only recommend wiping the connection down beforehand if you're thorough.Thank you. Are you going to test your cylinder by opening it a little without a regulator? I saw a video doing that to blow out dust etc
