Its expensive so use every bit.Thanks chaps
That is due to the full size bottle.Smaller bottles when the gauge reads empty they are empty, nothing in reserve. When I used my welder for a living (full size bottle) I also found that when the gauge read empty there was still a fair bit of welding could still be done. Great early warning.A regulator at work gets down to nothing quite a long time before it actually runs out, I nearly swapped a bottle out because it was 'almost empty' but ended up using it until it actually died and managed to make a couple of gates on what was actually left.
