Shielding-Gas Cylinder Runtime and Cost
Gas used, runtime per cylinder, cylinders needed, and the prorated gas cost from a flow setting and arc-on time. Compressed-gas and hot-work hazards govern; follow the maker's instructions and your hot-work permit.
Formula and source
Gas used = flow x arc-on / 60; runtime per cylinder = cylinder volume / flow; cylinders = ceil(gas used / cylinder volume); job gas cost = (gas used / cylinder volume) x cost per cylinder, prorated.
Torch / regulator maker's flow charts and the AWS welding cost / consumable references, by name.
