Ran a whole bunch of pending welding jobs past my Miller and found at the end that I had around 150 or so lbs of C15 left in the bottle. Unshipped the bottle from the rack on the dolly and loaded it onto my custom built whee-ler that I designed for this purpose (among others) Ran the dying bottle out to the truck and took it back to the supplier and picked up a replacement. Came home.
Only to find, that when I installed the gauges, the taper on the gauge fitting was not seating inside the shut off valve on the bottle correctly. Turned out that the seat in the valve body had gotten scratched or nicked and was pissing gas no matter how hard the gland nut got leaned on. Since that nut is brass and can be hurt, I elected to phone the rep at the supply house and tell him that this bottle was being returned and that I wanted another.
90 above out with a 64% or better humidity and here I am humping gas bottles in and out of the p/u box of my S-10.
Got the second bottle home and loaded into the bottle tray on the dolly and installed the gauges. Opened the bottle valve and Hisssss. Gave the wrench on the gland nut another smack with the palm of my hand and.............Sir Hiss was gone. Back in business. Full bottle holds about 2500 lbs of gas; the first one lasted me just about a year, even with doing body panels and some weird and strange bits like shortening a seat spring assembly and creating a palm plate for the jack that lifts my cherry picker so I can deploy the legs, and tacking together some remnants of mesh to use for a concrete repair job and, oh yeah, fabricating and assembling a custom whee-ler; you get the general drift here. The whole seat thing is a non G-Body shtick so over there it goes.
