Cutting with Oxy Acetylene

Cutting metals in the welding shop can be done with all kinds of machines for all kinds of budgets. Maybe you like to do your work the old fashioned way. If so, it’s likely you are using good old oxy-acetylene torches to accomplish your cuts. Let’s go over the basics of this tried and true shop method. Remember, for the best source of welding gas in Georgia, you can depend on Sidney Lee Welding Supply in the Atlanta area.


Acetylene is the most sought after welding gas due to its high flame temperature, and when mixed with pure oxygen that temperature gets even higher. This made oxy-acetylene welding the most popular method in the early days before arc welding become established in the trade. So even though you probably have switched up your welding equipment to a modern setup, you might keep oxy-acetylene welding gases around for cutting work. If so, be sure to check out our inventory of the finest Purity-plus certified welding gases at the Sidney Lee shop closest to you in Hampton, Conyers, Macon, Douglasville, and Atlanta, GA.


The first step in using the right welding supplies for the job at hand is to select a welding gas regulator that will deliver the appropriate pressure for the kind of metal being cut. Contact the experts at Sidney Lee’s service department if you’ve got questions. Then you’ll be able to choose the right cutting tip for the kinds of projects you have in mind, too. Once you’re in operation with the right welding supplies, learn how to operate the valve controls to ensure the best flow of welding gases. Because unlike using shielding gas for welding, for which you can mix gases into one tank, for oxy-acetylene you need to use a two-tank setup with separate oxygen and acytelene gases. Remember to keep the oxygen flow wide open when the cutting is underway. Always make use of the best safety equipment and procedures, since the hot flame can obviously do any amount of unintended damage if even briefly pointed in the wrong direction. Learn how to operate the torch so you can control the ignition, and then establish a neutral flame with a sharp inner cone. After that, depress the oxygen to gain a carburizing flame with a nice feather. Then you are good to go: dig in and cut that steel in the shape you desire.
