Negosentro.com | Top Oxy-Fuel Cutting Tips You Should Employ | Oxy-fuel cutting is fast, accurate, as well as cost-effective. It can give you the precision you need when it comes to cutting metals. The oxy-fuel cutting equipment isn’t expensive. Even more, you can rent it at an affordable rate. This makes oxy-fuel cutting one of the most regarded engineering cutting techniques on the market. However, having the best cutting equipment doesn’t directly translate to accurate cutting. You must master the technique and have the right skills. The following oxy-fuel cutting tips are all you need to achieve accurate cuts.
When opening the cylinder valve, it’s always advisable to stand aside. In case the regulator fails, it’s more likely to fail in such a way that it directs the force of the gas toward the regulator bonnet as well as the pressure adjustment knob. Once you’ve done this, open the oxygen cylinder valve fully. But for the acetylene valves, just open them one-half to one-full turn.
Conduct a Leak Test
Using a wrench, tighten all metal-to-metal connections. Then, saturate them with leak test fluid and check for any growing bubbles. Always utilize approved lea test solutions for better results.
Choose the Right Tip Size
To get the best cut quality, consider using the right tip size and then adjusting gas pressure according to your specific requirements. Note that flow rates might vary between different brands, so be sure to refer to the tip chart if you aren’t familiar with a particular torch.
What about the Pressure Drop
When utilizing narrow diameter and long lengths of the horse, make sure that the pressure doesn’t drop by the time it gets to the torch. Compensate for the pressure decrease by raising the regulator delivery PSIG (pounds per square inch gauge). This will ensure that the back-of-the-torch pressure perfectly meets your cutting tip requirements.
If you frequently cut long distances from your cylinders, check that there’s a precise pressure drop for your rig. Incorporate pressure test gauges and monitor the difference between the cylinder’s outlet pressure and the torch. Gradually increase the regulator’s PSIG until the torch gauges match the desired pressure.
Consider Bracing Yourself
Always support your cutting hand with the other free hand. You could easily accomplish this by bracing your free hand on a piece of scrap.
Before piercing steel using the cutting flame, make sure that the steel has reached its melting point. Whereas a reddish-yellow color is a positive indicator, you can always confirm the temperature by faintly depressing the cutting oxygen lever. You may also want to consider releasing the cutting oxygen lever and maintaining the pre-heat a little bit longer.
When piercing, begin at the center and slowly work outward towards your cutting path.
The Bottom-LineAchieving accurate cuts in the oxy-fuel cutting technique isn’t that easy. It involves a lot of skills. Plus, you must master the cutting technique. You should understand how to use the equipment. Also, it’s important to understand the oxyfuel cutting process.The above tips will help you use oxy-fuel cutting equipment for accurate cutting.
