Hi all, I finally found some 1/4" 20" pipe (new) in town and picked it up yesterday so I have started gathering the rest of the materails I need. It will basically be a Yoder clone.

My craftsman torch set has a #1 cutting tip but it shows for 5/8-1" and #0 for 3/8-5/8" thickness of material.

To get the best cut what do you all reccomend for tip size and oxy/act pressure settings?

Thanks,
John

John, I would use the #0 tip as recommended. The kerf on your cut will be much smaller. On my Victor regulators I run my Acetylene at 7lbs. and my Oxygen at 20lbs. These settings rarely change. Never bring your Acetylene above 15lbs. I run a Victor 0-1-101 for 1/8' to 3/8'' metal. I would imagine your #0 is about that size. Make sure your tip is clean and stays clean for the best cut. On cutting long runs such as 20'' to 24'' pipe I might stop and clean my tip at least once during the cut if it starts getting ragged on me. I hope this helps. Smile

Your very welcome John. You can practice on some plate to fine tune your regulators, they might run better with a little more or less. Also when cutting make sure you are comfortable for at least a 6'' to 12'' run. This will allow you more control on your cut.

I like the ought tip for that thickness as well but I have always set mine at 5 and 40 unless I'm brazing.

+1 on those settings for oxy-acetylene but Kevin's settings will work too Wink Just practice on some scrap coupons or plate until it cuts good for you.

I will increase the Oxygen up to 30+ if I am cutting 1/2'' or better, but then I am also changing my tip. I have not had to cut any thick plate in a while.

Whoops... Embarassed missed the part about only 1/4". Thought for some reason it was a question on settings for 5/8" Embarassed Less than 1/2" I run 5-7lbs acetelyne and around 20lbs. on the oxygen. And yes, use the #0 tip. Quick check-make sure the tip(s) you have are for acetylene and not for propane, as it will make a diference.

Just a side note for anyone fairly new to an O/A rig and new enough / silly enough here to ignore k.a.m.'s advice. It is not because it will not work, run bad, or some other trivial matter. It is because it may BLOW UP when the gas becomes unstable above 15lbs.

the above link is about dead on for a perfect cut if you can get your cutting speed right. oo for 1/4 plate 25 psi ox 5 psi acet.

If you can use a straight edge to get a straighter cut. I use a piece of 1 1/4" angle iron and clamp it down on both ends. Use a piece of scrap to figure out your off set to get the cut exactly where you need it.

Thanks for the reccommended pressure settings on the O/A guages. I had always run them on the high side and that was only because my father done so and I never thought to ask why. Was probably wasting a lot of gas for nothing too.
I do have a question about the guages.When you open the O/A valves on the tanks to the guages are the regulators left at the last pressure used or do you turn the regulators off and then the tank valves off?
I have had regulators fail on me twice. The first blew my hose. The second time I caught it before it happened. The guy at the welding supply told me that turning the regulators off first would prevent this from happening. The kits for the regulator repair are expensive. Just wondering if this is the correct way or not.

While not entirely sure why Rolling Eyes I shut my tanks off first, bleed the torch second, and then put a small backoff twist to both regulators and just reset my pressure next time out when shutting it off for the day. The not sure why applies to the reg backoff, it just seems right.

I have left mine set at 5 and 40 since I bought them. I never had a problem other than the time one of my kids tweaked on them for me without my knowledge. Laughing I run the air at 40 with the ought tip to give that extra blast when cutting but that is just me. The only advice I would give anybody is to crack the bottle valves open very slowly at first until the line is pressurized just in case you have regulator failure. This protects you, the other is never screw the regulator valve all the way in. There is a very thin diaphragm over the seat that will be damaged if overtightened, this protects the equipment. Again, just my opinion and you know what they say about opinions. Very Happy

it is recommended that you back off your gauges turn them off and bleed your torch. but if you have a good quality regulator and hose this should not be an issue.

Turn off the tank(s), bleed torch head (oxy then acet, or vice-versa, never both at once), back regulator(s) off...everytime. This is how I do it. Dad taught me, and I listened. Wink Hard chance of blowing a reg this way.

Gas settings worked great!

I cut my firebox section of pipe from the 5' so now I have my cooker section 40" and the firebox 20". Picked up my end pieces I had laser cut and smoke stack is ordered.

Figuring legs out now.

Being as there is no room in my garage I have to work outside and its going to be a cold and windy weekend so fingers crossed for next weekend to get some welding done!
