Long story short, I was using way more gas than I expected I would. I'm halfway through a bottle of hobbyweld ultra argon and at the rate I was using it my first project was going to cost me more in gas than steel.
I switched from a #8 cup to a #4, turned the regulator from 7l/m to 4l/m in an effort to finish my project on a single bottle.
Hit the foot pedal and the little #4 cup sounded like a cutting torch.
Now highly suspicious I ordered one of those torch end pea shooters. Sure enough 4l/m on the bottles build in regulator had it off the scale hitting the stopper at the top of the tube. I turned it down till it was 10l/m on the pea shooter and it didn't even move the needle on the bottles gauge so God knows how much gas I was actually using when the bottle was reading 7l/m.
Obviously a rookie mistake, I'm sure most would of noticed straight away but with no point of reference I was none the wiser. Is it normal for these guages to be so far off? Wondering if I have a case for a discount on the next refill..
