Therefore, you need to be extremely careful when starting your welding process. The gas cylinders should be sealed to perfection, with no leaks at all. Now when I go to adjust this, I’m probably going to adjust this thing to about 5 PSI. I’m going to run this at about 10. The Oxy-Acetylene welding equipment consists of oxygen and acetylene gas cylinders, pressure regulators, hoses, Flame Arrestors, welding torches, and economizers. I'm Pierre Young. When the welding torch is resting, the flame is extinguished automatically. Think of the two numbers, 10 and 5. The filler rod is held in place such that it is in front of the nozzle. (SCFH) Metal With Use Size Part No Price (PSIG) Each Gas Size Torch Mixer 0 23-A-90-0 $15.50 EA 5 3 1/64" 1 23-A-90-1 $15.50 EA 5 5 1/32" 2 23-A-90-2 $15.50 EA 5 8 3/64" It comprises oxygen and acetylene gases stored under pressure in Oxy-Fuel To Acetylene Flow Use SIWS Equal Press. We have listed down the most common hazards of this type of welding below: Gas welding is one of the riskiest of all types of welding. Oxy-Acetylene is a volatile mixture of pure oxygen gas and acetylene gas. *** All pressures are measured at the regulator using a 25' X 3/8" hose for tip size 6 and larger. This temperature is hot enough to melt all types of commercial metals. The big thing you need to remember about tips is that they must be clean. This type of flame is used in most welding operations since the chemical effect of this flame on heated metal is the least. i found that dropping the oxy to 20# for rosebud operation works well. This way, the entire surface is gradually built up. Once you have a clear understanding of the equipment, you will know exactly how Oxy-Acetylene … Navy FR Cotton... Reusable Half Face Cover, NASUM M101 Face Cover,... Make sure that you’re always wearing protective clothing (flame-retardant overalls) and protective eye goggles, The acetylene gas cylinder valve should have a spindle key, The gas cylinders should be stored in an upright position, Check for leaks with a soapy solution and not with a naked flame, Do not carry out any makeshift repairs on your welding equipment, Prevent the contact of your oxygen equipment with oil or grease at all times, Clean enclosed vessels thoroughly before welding them, If you’re working in an enclosed vessel, make sure you aren’t alone and that the gas cylinder is always outside, Fire-fighting equipment should be available on the ground, Turn the gas supply off immediately if you detect a leak in the hose. This thing is ready to go now. The Oxy-Acetylene welding equipment consists of oxygen and acetylene gas cylinders, pressure regulators, hoses, Flame Arrestors, welding torches, and economizers. When oxygen and acetylene are mixed in right proportions within a blowpipe or hand-held torch, they can produce a very hot flame, with a temperature as high as 3,200 degrees. Re: Oxy-Acetylene Settings??? The filler rod is moved forward in a circular motion, with the blowpipe moving steadily along the seam of the weld. Yes, aluminum can be welded with Oxy-Acetylene. I've learned from hands-on experience what welding gear works and what doesn't. I've had brand new cylinders (#4's) do this. 13.0 Oxy-fuel Cutting Procedures 42 13.1 Cutting Attachment Operation 42 13.2 Setting Up 43 13.3 Lighting Up 44 13.4 Closing Down 45 14.0 Oxy-acetylene Cutting Techniques 46 14.1 How it Works 46 15.0 Using the Cutting Assembly 48 16.0 Mild Steel Cutting 49 16.1 Thin Steel 49 16.2 Thick Steel 49 17.0 Good and Bad Cuts 50 Make sure torch valves are closed! Recommended oxygen and fuel gas pressures are at the torch with gas flowing. You’ll notice that the acetylene gas has a mark around the fitting. 38. If additional flow capacity is required, use an 3. by welder57 » Sat Jan 22, 2011 1:55 am i set mine at 40# oxy and 5-7# for general cutting. Remember when I’m setting this regulator I’m not going to get up to 15 pounds. There are different types of techniques that you can practice, which have been listed below: The leftward technique of Oxy-Acetylene welding is employed to weld steel plates that are up to 5mm thick. At this point, the rod is melted onto this sweating surface in small deposits. the torch manu. First we’re going to adjust the regulator before we get started. The primary components of Oxy-Acetylene welding equipment are separate gas cylinders for oxygen and acetylene. 4.5. Pressure (PSIG) Fuel Pressure (PSIG) Oxygen Consumption (SCFH) Fuel Consumption BTU Per Hour 6 8/20 2/10 20/80 5.5/20 See Chart 8 10/20 10/15 40/140 10/35 10 10/30 12/20 80/320 20/80 12 30/125 15/25 120/640 30/160 15 30/125 15/25 200/800 50/200 20 40/135 15/25 300/1000 75/250 WARNING: Not for use with acetylene Now I’m going to set this thing to about 5lbs. Now I’m at the oxygen. Next, open the control valve for fuel gas present on the blowpipe and adjust the regulator until the correct working pressure is achieved. Welding joins different metals together by heating them at the junction up till the point they melt and fuse together. So these cannot get mixed up. If I’m going to set this regulator, I want the gas open, because I want to set the pressure while there’s actually gas coming out. The joint that is formed as a result of this type of Oxy-Acetylene welding is absolutely clean and has excellent mechanical properties. This technique comes with numerous advantages. Oxy-Acetylene welding involves joining two metals with the help of a flame produced by the combustion of oxygen and acetylene. The chemical action of the oxy/acetylene flame can be adjusted by changing the ratio of the volume of oxygen to acetylene, using the valves on the torch or blowpipe. Once you have a clear understanding of the equipment, you will know exactly how Oxy-Acetylene welding works. The recommended setting for multi-hole cutting using oxy acetylene is the oxygen regulator at 40 psig with the acetylene regulator setting at 10 psig. Now if I shut it off, it will go up a pound or two. Once the flame ceases to smoke, increase the oxygen supply slowly by means of the control valve. Again, this is loose. After the pressure of the gases has been regulated and controlled, they are fed to the welding torch through the respective hoses. Gas is a fuel gas, because you don’t have to use acetylene, although you’re nuts if you don’t. The regulator also becomes a safety issue because it controls the pressure of gas and helps to connect it to gas supplies. Always your oxygen should be at a higher pressure than my acetylene. Back you your question. more pressure as tip size increases (15 PSI maximum acetylene pressure). Before you start with the leftward technique, play the neutral flame at the edge of the joint until a molten weld pool is formed. Moreover, a pressure regulator should only be used with the gas it has been designed for. 10-12 psi (never exceed 15) on the acetylene and 35-40 on the oxygen. Cutting Speed mm/min. Each gas is controlled by the valve present on the torch. The temperature of the flame is hot enough to melt the edges of the metal, and hence, fuse two metal pieces together. 450. Well let’s take a look a little closer at the gauge. Acetylene 1/MIN. They are ignited and burned at the nozzle of the torch. Acetylene. In this technique, it is important that the edges of the metal to be welded are not melted but heated until they become red. Acetylene: Welding is a process whereby two (2) metals are joined together. You should make sure that you do not keep the filler rod dipped into the pool continuously as it would act as a hindrance to thorough heating and keep the heat from the flame to reach the lower parts of the weld, and this might result in an imperfect fusion. Every hose has a check valve that offers automatic safeguarding by incorporating a non-return valve. For this very reason, you should always open the gas cylinder valve smoothly and slowly with the help of the Spindle Key. In parallel, you should check the bullnose present on the pressure regulator. Oxy-Acetylene welding works on a simple concept, that is, bring two pieces of metals together such that their edges are touching. Consumption.

I prefer Victor gauges as they are the most accurate. These mighty metallic structures are heavy and solid. In case there is a leak around the spindle, it will be revealed by a hissing sound or a smell. So we need to consider what pressures we’re going to put on this. They don’t want you mixing these things up, because here again if you’re running acetylene, which is just full of carbon, through an oxygen line, it could explode. Oxy-Acetylene welding requires a specific skill set and thorough practice, coupled with which it can be used to weld virtually any metal! It should never be exposed to knocks or sudden surges in pressure that are a result of the rapid opening of the gas cylinder valve. What is the withdrawal rate of an acetylene cylinder? This type of flame is suitable for applications where a low-heat flame is required. Starving it for fuel/oxygen will cause the rosebud to heat up and back fire extinguishing the flame and followed by a wistle. 200. 380. As you change the ratio of the two gases used, the action of the flame is adjusted. Pressure regulators should be changed immediately in case of damage. 4. Make sure regulator pressure adjustment screws are backed out! That’s because this is left hand thread. 25. It involves laying down a layer of hard deposit on the surface or cast iron or steel. This site is owned and operated by Muller Media LLC. There should be no leakage in the hoses as these are the pipes through which the gas is transported to the torch. There are numerous types of welding, of which Oxy-Acetylene welding is one of the most famed welding processes. Some cutting tips are specially designed to use with automated cutting machinery for high-pressure cutting that permits quicker, cleaner, more accurate cuts. Written by Kupis on September 27, 2020 in Chart. A typical cutting tip has a large center hole where the acetylene-oxygen mix exits and 6 smaller holes evenly spaced around it. 200. The gland nut around the cylinder valve should be tightened clockwise using a spanner to ensure that no gas is leaking, thereby reducing the risk of accidents.
