What Size Welding Gas Cylinder for MIG or TIG?

The size of the welding gas cylinder needed for MIG or TIG welding depends on the frequency and duration of welding, the type of gas used, and the size of the welds being performed. Here are some general guidelines for selecting the appropriate size welding gas cylinder:

MIG welding typically requires larger amounts of gas compared to TIG welding. A 20 to 40 cubic foot cylinder of gas is typically sufficient for occasional light MIG welding. For more frequent and heavier MIG welding, a larger 80 to 125 cubic foot cylinder may be needed.

TIG welding typically requires smaller amounts of gas compared to MIG welding. A 20 to 40 cubic foot cylinder of gas is usually sufficient for occasional TIG welding. For more frequent and heavier TIG welding, a larger 80 to 125 cubic foot cylinder may be needed.

The size of the welds being performed will also affect the size of the welding gas cylinder needed. Larger welds will require more gas, and therefore a larger cylinder.

The type of gas being used will also affect the size of the welding gas cylinder needed. Some gases, such as argon, are used in larger quantities compared to others, such as CO2.

It is important to note that these are general guidelines and may vary depending on the specific welding application. It is always a good idea to consult with a welding expert or supplier to determine the appropriate size welding gas cylinder for your needs. Additionally, it is important to follow all safety guidelines and regulations when handling welding gas cylinders.
