The instructions for calibration in the lid don't seem so bad to me. For what it cost I'm sure it'll serve my purposes. I love old tools too! :D

Ok from what I can gather this is an adjustable, pressure limiting TXV. I think that's what I need after reading on what the pressure limiting does. Apparently it allows the system to work wider...

Great Value LED's

Put two 60W equivalent Great Value (Wal-Mart house brand) LED's in the other day. These things throw off way more light than 60W equivalent CFL's. Looks like it to me anyway. Only $8 for 4 of them.

That's making C25 look better. Lol, that's what I'm used to using with a MIG anyway so it's probably what I'll get.

Will keep an eye out every day till I have the cash freed up to order from Cyberweld if not. Just wanted to say I'm on page 42 of your aquaponics thread and that looks great!

75/25 argon/co2 works fine for brazing right? Bottle is more expensive but then I'd have a bottle to convert my Lincoln flux core welder to MIG.

Hm, I thought there wasnt much difference in the compression ratio between R22 and R4R410a. Like 3.2:1 vs 3.4:1 or so. Already have the 5k, but I could charge with 134a if it would be better, no...

Here's my regulator. Victor inert gas, max inlet pressure 3000psi. Seems like it would work for purging, since we wouldn't be trying to build pressure.
