Administrators Moses Ludel Posted February 25 Administrators Share Posted February 25 Anrique...I use a 75/25 mix of argon and CO2. That's 75% argon and 25% carbon dioxide. If you're welding mild carbon steel, which is the place to start as a new weldor, this is a good balance. According to Miller: Gas selection A 75 percent argon/25 percent carbon dioxide blend (also called 75/25 or C25) works as the best all purpose shielding gas for carbon steel. It produces the least amount of spatter, best bead appearance and won't promote burn-through on thinner metals. 100 percent CO2 provides deeper penetration, but also increases spatter and the bead will be rougher than with 75/25 Some additional quick tips for learning the right techniques can be found at Miller's website: https://www.millerwelds.com/resources/article-library/mig-welding-the-basics-for-mild-steel Moses Quote Link to post Share on other sites
