Weld Gas Flow Rate Adjuster
Fine-tune your MIG/TIG shielding gas flow rate. This tool provides a recommended starting point based on your welding position, environment, and wire/nozzle size to ensure optimal weld pool protection.

The Art of Gas Coverage
Getting the right shielding gas flow rate is a balancing act. The goal is to provide just enough gas to create a stable, invisible shield that protects the molten weld pool from the air, but not so much that it creates turbulence. The "right" amount changes depending on your specific situation.
- Position: When welding vertical or overhead, the heated shielding gas wants to rise. You need a slightly higher flow rate to compensate and ensure the gas stays where it's needed.
- Environment: Even a slight breeze can be enough to blow your shielding gas away, leading to severe porosity. In drafty conditions, you must increase your flow rate significantly and consider using physical wind breaks.
- Nozzle Size: A larger nozzle or cup diameter creates a wider column of gas, which may require a higher flow rate to be effective, especially with a longer electrode stick-out.
