CNC Oxy/Fuel Discussion

[WSS]

Here is a thread to post your Oxy/ Fuel cutting questions, ideas, problems and PHOTOS!

Let"s discuss codes, speed, gases, tips (consumables) or anything concerning oxy cutting.

And please don't be afraid to call "Dross" slag here. Oxy cutters will know what you are talking about!

Cheers!

I have been looking for a way to ramp up the cutting oxygen, Something like a soft start valve, or........... ?

I have found Retro plasma makes a regulator assy. with "Ease on pierce rate control ". They describe it as "The rate that cutting oxygen pressure increases during the pierce is
set by the Pierce Rate Control knob".

I can't find much info on this type of system on the net.......... Anyone familiar with this type of system?

Gentlemen:

I have attached (4) jpg's of a system and explanation. Hope it is of help to youall.

Regards,

This is interesting. I often have trouble piercing material above 1" thick

I am setting up a oxy / fuel cutter. I need all the help I can get.

Steve, have you made any more progress with your port 2 installation to get your system going?

Millman, I talked to Tom, and he said that I have the wrong version of the IO card. So I need to get the correct drivers installed.

I just finished replacing the 7/8 drive stem pinions with 2 1/4 gears. Now the vibration is gone, I am going to work on the IO card.


What Post processor is everyone using for Sheetcam?

Thank you JCC,
That is exactly what I have been looking for.

I wonder if this could be done with a small bore "oxy safe" air cylinder that has had the piston converted to a plunger and the rod changed to a 1/2-10 acme thread for adjustment? It would serve only one torch for the ramp up oxy. but might be doable. The ramp pierce is pretty handy to keep slag traveling in a rearward or away direction. The Hi PH could be done with a separate set of 3 way Asco type solenoids and a extra set of regulators. Once you found the right combination you could manifold the whole deal to pull from one (of each) bottle.

I converted the jpgs from jcc3inc's post to a pdf (Big thanks Jack!)

I'm afraid you lost me on that one!

Steve I had gone to the manuals on CandCNC's Yahoo site & done a bit of reading on installing the MP3000. Somewhere in there it mentioned the version of one of the cards needing to be current. It was yesterday evening when I was reading it & by now I can't remember the details.

Knowing your project has been a lengthy one just kind of assumed something slightly out of date might be your problem. I'm probably the worlds worst to buy something then let it lay for weeks or months before using it.

I started building an actuator type "Z" lifter & an new HT 1250 plasma nearly a year ago & still don't have that installed & am paying to have thin materials plasma cut. I can't really say I haven't had the time I just haven't made it happen.

Tom will get you through it. He has always had the answers I needed. Sometimes I can be shch a bonehead that it takes a week or 2 for what he is telling me to sink in.

I am using the Mach2 plasma.post for my oxy set up. (again I am running 2006 or so vintage MP1000 candcnc equipment)

...... It just dawned on me what you are describing!

The air cylinder could be controlled with shop air and it wouldn't need to be oxygen clean.
I will have to experiment with force requirements to see how big of a cylinder it would take.

The beauty of this is I have most all the stuff laying around to build it with!
Thanks for the idea!

Steve
