Thats novel! What pressure do you get from the fire extinguisher? Is the gas supplied for the fire extinguisher suitable/produce a good weld?

The gas pressure in the fire extinguisher is the same as in a normal cylinder. Carbon dioxide is no different. I put the pressure at the outlet about 0.2. I'm still just learning, but I like the seam.
Just turn the fire extinguisher upside down
