FAQs

As a trusted supplier of gas, we frequently get asked questions about gas safety, the difference between butane and propane, as well as the best uses for our gas products. In this blog, we’ll be answering our most common FAQs.

CO2 bottles are commonly used for MIG welding, particularly on mild steel, where strong penetration and cost efficiency are priorities. They are also used in workshops where high gas consumption makes CO2 a practical option. Adams Gas supplies CO2 bottles suitable for consistent performance in these environments.

Pure CO2 offers deep penetration and lower running costs, making it popular for heavier fabrication work. However, it can produce more spatter and a rougher finish than mixed gases. Many professionals choose CO2 when strength and cost matter more than appearance. Adams Gas provides CO2 bottles that allow users to make that choice confidently.

Bottle size should be chosen based on usage frequency, weld duration, and whether portability or reduced downtime is more important. Smaller bottles suit occasional or mobile work, while larger bottles are better for workshops with continuous welding. Adams Gas offers a range of CO2 bottle sizes to suit different working patterns.
