Oxy-Fuel Torch Cutting Thick Steel – Fast, Hot, and Precise ????⚙️ - Video

Watch a worker preheat a thick steel plate with a mixed flame of oxygen and fuel gas (acetylene or propane). Once the metal reaches kindling temperature (about 1800°F / 980°C), he triggers a high-pressure oxygen jet. The oxygen reacts with the iron, producing intense heat that melts and blows away slag, cutting through inches of steel in seconds. The edge is clean, slightly oxidized, and ready for welding or further fabrication.

Let's Talk Oxy-Fuel Cutting!
Why is pure oxygen used instead of just a flame (it chemically burns the iron, releasing more heat than a torch alone)? How thick can a handheld torch cut (up to 6 inches, thicker with larger tips)? What safety gear is mandatory (dark goggles, flame-resistant jacket, gloves, steel-toed boots)? How do you avoid slag sticking to the back of the plate (start cutting from an edge, or pierce with a slag hole)? Can you cut stainless steel or aluminum with this method (no – they form refractory oxides; use plasma or abrasive instead)? Share your metalworking experiences, torch handling tips, or questions about gas pressures in the comments below. Let's cut metal the old-school way!
