"Webb30 mars 2024 · 2. Argon is non-toxic, making it safe to work with. 3. Gases such as argon are cheaper than other gases, making them a cost-effective alternative. 4. Argon has a low vapor pressure, meaning it doesn’t escape easily from the welding area. This means there is little chance of spatter or build-up on the weld area. 5. " - Ti-gettered argon atmosphere
