[TheForge] Sidearm burner parts

But PSI is only one part of the picture. That combined with the 
orifice size gives a better idea of how much gas is being used. 
And if you wanted to get real anal about it, you'd have to figure 
in all the plumbing between the pressure meter and output. One 
thing I've wondered about is how does the length of the MIG tip 
affect things? That's a longer "pipe" at a very small diameter. 

I have a feeling that the 8oz burner has a much larger orifice. 
And at that low pressure probably has a blower. I have seen burner 
designs that used a 1/4 pipe open-ended to feed the gas. And those 
required blowers, but ran off of normal "house" pressures, 
measured in inches of water column, which are less than 1 psi.

The only number that would make sense for comparison reasons would 
be flow rate, but I don't know of anyone who's ever put a 
flowmeter on a burner.
