How To Set Oxy Acetylene Regulators
How to set the oxy acetylene regulators
I'm going to tell you how to set the pressure regulators and probably get into torch tips and a few things similar that for oxy-acetylene. It's very important how you lot set these things. You know the loftier force per unit area and the oxidizing trouble with oxygen if there's whatsoever carbon present. The acetylene can't be over 30 pounds. In fact, if you expect on the gauge you can encounter annihilation over 15lbs. in red, and of course it tops out at 30lbs. So we need to consider what pressures we're going to put on this. They're definitely going to be below 15. I prefer Victor gauges as they are the most accurate.
Showtime we're going to adjust the regulator before we get started. If y'all turn it clockwise, that increases force per unit area. That's a niggling backwards from most valves, but that's the manner a regulator works. When you start it should be loose. Now go ahead and plow on the gas. Now this is acetylene, this one is only running 235 pounds of force per unit area and, of form, I'm zeroed here because there'southward zip coming out. At present when I go to adjust this, I'thou probably going to adjust this thing to about 5 PSI. If you look you can meet information technology says oxy and gas. Gas is a fuel gas, because you don't accept to use acetylene, although you lot're basics if you don't. If I'm going to set this regulator, I want the gas open, considering I want to fix the pressure while there'south actually gas coming out. So I've got that open. Well let'south take a look a footling closer at the gauge. As I start turning this down it'southward going to have a little more resistance, and the pressure level will go up. At present I'one thousand going to set this thing to most 5lbs. Now if I shut it off, it will go upward a pound or two. That's why I want to do information technology running.
Now my acetylene regulator is set. Remember when I'yard setting this regulator I'm not going to get up to fifteen pounds. Continue that sucker way downwardly here someplace. If yous've got a pretty practiced sized tip you're gonna have to become upwardly a little flake higher on that, but don't go above 15 pounds.
Now I'm at the oxygen. Again, this is loose. Before I start, I open, the gauge and it goes up, I've got most 700 pounds in there, and again, as I did earlier, I'll put this matter up here, I'm gonna go to oxy, and I'm going to open information technology. I outset cranking this thing downward, and information technology will beginning coming up. I'm going to run this at about 10. Think of the 2 numbers, 10 and v. Always your oxygen should be at a higher pressure than my acetylene. You may want to run that up to 12 or 13, something similar that, merely for torch work, braising in the calorie-free, you usually don't need it much higher than that. For cut everything is different and the oxygen force per unit area should be virtually 25 PSI.
This thing is ready to go at present. I of the things I'm going to do right at present is show you what's incorrect with my torch. There should be cheque valves in the torch body. All new ones have bank check valves. One of the reasons I make certain my oxygen is e'er college than my acetylene is so that nosotros do not get into a situation where acetylene could actually go dorsum into the oxygen line. And then it could burn inside the line. I've washed this for and so many years, possibly I'thou just set in my ways. You'll notice that the acetylene gas has a mark effectually the fitting. This one does not on oxygen. That's because this is left hand thread. They don't want you mixing these things upwards, because here again if you're running acetylene, which is simply total of carbon, through an oxygen line, it could explode. So these cannot get mixed up. That's a regulator set up. Next we're going to go into the torch tips and how to set the flame on the oxy acetylene welding rig.
The big affair you need to remember about tips is that they must be make clean. A typical cutting tip has a big center hole where the acetylene-oxygen mix exits and vi smaller holes evenly spaced around it. The small holes are for the high pressure level oxygen that blows the slag abroad. All vii holes must be clean for the cut torch to work efficiently. Tip cleaners are made by Weldmark, Lincoln, US Forge, and Tech Squad https://techteamproducts.com/. We like Tech Team's (https://www.amazon.com/dp/B07NGV9CS2?ref=myi_title_dp) the best because it has all the necessary ream files and a handy storage case.
