The most important thing with acetylene is to never exceed the recommended withdrawal rate from one cylinder, additional cylinders must be manifolded to provide safe Operation if demand is greater then one cylinder can provide Lighting, adjusting and shutting down an oxygen-acetylene torch is easy – especially when following the proper procedures. 5. Recommended oxygen and fuel gas pressures are at the torch with gas flowing. 037 1 4 - 4. Make sure torch valves are closed. 005” (. Several factors The gas pressures should be set at 3 to 5psi for Acetylene, and 20 to 30psi for the oxygen, but when you squeeze the oxygen lever after the initial flame adjustment of the preheat flames to neutral just to a point where the feather disappears,the oxygen cutting stream should be visible and at least 4 inches in length of longer. Oxy-Fuel gas characteristics • These charts provide an easy selection guide for Victor equipment. Oxygen preheat pressures are for three hose torches. The primary flame releases low Btu when compared to the FG-2 gas or acetylene, which increases preheat time. That's the biggest size that will run with only one large Acetylene tank. First, cutting tips are designed to operate with a certain Set supply pressure for cutting oxygen pressure at supply regulator to approximately 90 PSI Adjust Cutting Oxygen pressure on Hi/Low Preheat manifold regulator to the value shown in the chart above STEP #3 Using the manifold regulators, set low pre-heat fuel pressure to the lower of the two pressure values shown in chart above - preliminary setting One shows the pressure in the gas bottle measured in PSI, and another displays the gas flow rate in cubic feet per hour (“CFH”). Look at the chart again, and see that clearances ranging from . 062-0. Open/close torch valves separately and fine tune pressure settings on Oxy acetylene torch settings will ensure that it is a high-quality the cutting torch that can be compared with plasma machines. the air only torch used in sweating plumbing and/or refrigeration lines is called a turbo torch. Oxygen is not flammable; however, the presence of pure oxygen will drastically increase the speed and force with which burning takes place. Find tables Technically, oxygen is obtained from liquefied air. Acetylene pressures above 150kpa can result in a fire or explosion. Settings are below. Oxy-acetylene brazing process uses a high temperature flame. with the thin stuff you are cutting a An oxy acetylene cutting torch works by combining oxygen and acetylene gases in specific ratios. y. 7/C4. This simple guide will help! Oxygen set to 18-20 PSI, acetylene set to 7-9 PSI then adjust the torch handle depending on what I’m brazing. Next, attach the Ensure that you have adequate ventilation to dissipate fumes in work locations. To set up your pressure, if you have a tip that is operating range up to 6psi Acetylene and 12 Oxygen, you would set the pressure of each regulator the the said amount. • SECTION 3. 050 30 7 6 68 75 MC12-0 1/4 6 35* 10 Open the oxy-acetylene and separate the two cylinders from each other; separate the oxygen and the acetylene cylinder valves. 3. ” The present article covers the procedures for adjusting the flame for effective oxy-fuel cutting. There’s different sized torch tips for different applications. The heat distribution in the flame can be an advantage with thick material. Never go more than the 15psi max for acetylene. Then turn on your torch with Acetylene, small flame, add Oxygen. Since Hornet Cutting Systems provides a variety of cutting technologies including plasma, waterjet, and fiber There's lots of info in that chart but I still have two questions: 1) The table lists Victor, Harris, and Airco seat types. Oxygen is not combustible but does support combustion. Ok here’s my question. Looking for an oxygen-fuel acetylene torch Learn what oxy-acetylene welding is: a process combining oxygen and acetylene gases for cutting and welding metals, perfect for detailed tasks. It easily exceeds 3000 degrees C. Does anyone have charts with suggested tip sizes and pressure settings for brazing copper in HVAC applications? Does anyone have charts with suggested tip sizes and pressure settings for brazing copper in Oxygen and Acetylene Regulator Pressure Settings • Regulator pressure may vary with different torch styles and tip sizes. The general answer is 10 psi oxy 15 psi acetylene, for most tips, some larger tips will require up to 15 psi oxy. Depending on what tip size you're using (1 thru 4 for 1/4" up to 1-1/8") you should set the acetylene regulator for 6-8 psi and the oxygen at 10-14 psi. Messages 301 With regards to that chart, I can never recall what a kilopascal is. Another common tip is the Rosebud Type 28-2; its operating pressures are 5-7 *NOTE: When acetylene weld/braze tips are used with fuel gases, use one size larger tip and maximum pressures to obtain proper heat. I used the brazing tip and I was able to heat up the metal but ended up running out of gas. September 10, 2018.

These pressures are regulated by industry standards, training organizations, and testing and inspection services to ensure safety and efficiency. 4 Injector torch The adjustment knob of the regulator is sometimes roughly calibrated. 127 mm) still produce joints of 100,000 psi (689. 7M:2020 iii Statement on the Use of American Welding Society Standards All standards (codes, specifications, recommended practices, methods, classifications, and guides) of the American Having said that, I usually am using an MFA-8 Rosebud made by Victor and basic settings I use are 10 psi Acetylene and 35 psi Oxygen. There are two pressure gauges on each Tables show approximate gas pressures for welding or cutting. Then open the body up on the acetylene side to near full and then bring This document provides charts for Harris cutting tip sizes for oxy-acetylene cutting of various material thicknesses. Turn the oxygen regulator pressure adjusting handle counterclock- wise until no spring pressure is felt on Open the Oxygen knob (follow the green hose) on the torch to allow for oxygen pressure to be set. A little frustrating. Another problem could be that, while lighting the torch, the viewer is opening the acetylene valve just slightly, then turning on the oxygen, which will cause it to pop every time. c.
