gas flow for welding
By Ryan Perry

Can you accurately flow a different gas through a flow control device not calibrated for the same gas?

Quite often, when in the field, it becomes necessary to use another gas through a flow control device such as a flowmeter, flowmeter regulator, or flow gauge regulator. While the flow control device may be safe and compatible for the other gas, the issue often becomes one of accuracy.

Harris two-stage regulator
By Harris Products Group

Two-Stage Regulators

The basic function of a gas pressure regulator is to reduce unusable high pressure from the source to a lower usable delivery pressure. Two-stage regulators are designed to lower the high pressure in two stages. They require less readjustment and provide a more constant delivery pressure despite changes in inlet pressure. They are exceptionally well suited for high pressure cylinder applications.
