It's actually 6 now. But they are all off the same amount. If I bend the cowl piece up about 3/16" they will all align because the ones with bolts in them now will move with the cowl as I bend it.

But that does not compute since the top piece ends where I cut it will no longer be flush. I dunno....

Yes, I understand what it does. But does it loose all the argon while still having Co2 left? Because the tank still has pressure in it if I just open the valve. And when the regulator is hooked up the regulator allows me to adjust pressure and will stay about 20, where I have it set, but the tank pressure shows zero.
The stranger thing is that I just tried welding again before I took the tank to be exchanged, and it seemed okay. Now I'm baffled.
I wouldn't think I'd go thru that much gas that quickly, but I don't know, hence my question to you guys.

I don't weld a ton or every day but my tank is smaller, about 2' tall, and I got it last fall. It is showing 1500 psi on the main gauge so after a yr it still has plenty of gas. Wonder if you have a leak at the regulator?

The argon and CO2 are mixed together. I don't believe that it's possible to run out of argon, and still have some CO2 remaining.

So...if you have the tank valve completely closed (overnight, let's say...), then you open the valve, the tank pressure gauge needle doesn't move at all? Not even the slightest bit?

And yet, you can still set the gas flow at 20 cfh? If so, I would say that your tank pressure gauge is not exactly accurate ( kinda like stock CJ gauges...).

To check to see if you have a gas leak, you could mix up a few drops of liquid dish soap with some water in a spray bottle. Open your bottle gauge valve, and check all the connections with the soapy water mix. Look for bubbles...

You should get quite a bit of welding out of a tank of gas, providing that there are no leaks. My guess is that your tank pressure gauge isn't accurate, and that you have more gas in the tank than that gauge shows.

Well that may be the problem. It's a Northern Tool 135 welder and regulator. I didn't try a soapy water mix but I will tonight. I may even pick up a Hobart regulator at TSupply on the way home. You guys are confirming my suspicions that I should get much more welding from a tank. Thanks

Windex makes for an awesome leak detector. Spray it on an watch it foam!

I'm looking for a Scout II Dana 300. Drop me a line if you have any leads. Thanks

Rolf Harris, "the Boy from Bassendean" just up the road from me. He's the guy who painted secenery pictures using only rollers and giant house paint brushes. He also painted a portrait of the Queen (of England). That must be who hes talking about. Very famous. Sang a sondg called "Tie me kangaroo down sport".

Whatever.

Hum a few bars, Gazzo, and I'll see if I can pick it up!

Tried the windex and found no leaks. Called up Northern Tool and a new regulator is on the way. Thanks again guys.

And for your listening pleasure....
