Duration of Welding Gas
The duration of welding gas is essential for efficient project planning, and it can be calculated by dividing the tank’s volume in cubic feet by the gas flow rate, which typically ranges from 10 to 40 cubic feet per hour (CFH).
For example, an 80 CF tank operating at a flow rate of 10 CFH will last approximately 8 hours before you need a refill.
Keep an eye on the pressure gauge to monitor the remaining gas; a full tank reads around 2015 psi, while a 50% spent tank shows about 1000 psi.
The actual gas consumption varies based on the type of welding and the specific flow rate you set for your operation.
Although welding gases don’t expire, gas mixtures can separate if stored too long.
If that happens, lay the tank horizontally and roll it gently to remix the contents.
How to Know When You Need More Gas
How can you tell when it’s time to refill your welding gas? Start by monitoring the pressure gauge on your gas tank. A full tank typically reads around 2015 psi, so if you see it drop below 1000 psi, it’s time to refill.
Additionally, calculate your gas usage based on the flow rate; for example, an 80 CF tank at a flow rate of 10 CFH lasts about 8 hours. If you notice a decrease in welding performance or instability in the arc, that’s another sign your gas supply may be running low.
