Preheat and flame cutting power (acetylene flow, oxygen flow) should increase with the increase of the plate thickness; 2. Using diffusion-shaped tip and cutting oxygen curtain cutting nozzle plate thickness 20mm or less, the fire power should be large Some flame straight cutting machine sales site, in order to accelerate the leading edge of the incision is heated to ignite, resulting in a higher cutting speed; 3. When cutting thicker steel, mild carbonation flame flame is appropriate, in order to avoid melting the upper edge of the incision collapse, while also allows Waiyan longer; 4. single bevel cutting torch tip, because the slag was blown lateral incision for supplemental heat Xinyang straight flame cutting machine business, to increase the power of the flame; 5. Cutting carbon at higher levels or higher content of alloying elements of steel, because of its high ignition, preheat flame power to a large number; 6. LPG or natural gas as the gas, because the flame temperature is low, warm-up time is longer; cut small parts such as the frequent need to preheat the occasion from the cut, in order to improve cutting efficiency, the flame can be adjusted to oxidizing flame, and then start cutting back to the neutral flame.
