propane/ acetylene hoses are different than acetylene only hoses and then only the tips are different after that.

Thanks Tom, I will look into repacling the hoses and getting some tips...I appreciate it..

Your fuel regulator should thread right in to your BBQ propane tank. You will need an oxygen tank. I don't know how much it is to buy the tank new. I got my two tanks and the welding outfit (hoses, regulators, torch and tip) for $100 used. I had to pay $20 for a hydro test on the oxy tank when I exchanged it plus another $20 or so for the gas. The acetylene tank was about 1/2 full. I'm sure I'll have to pay for another hydro test when I exchange the Ace tank.
I still need to build a cart. I have some spare front tires off a riding lawn mower that I'll use for the wheels. No dinky dime sized hand truck wheels for me! That will probably be another thread.

Thanks Iplay. that gives me more ino that will help a lot. I was thinking of making a cart out of an inexpensive hand cart I have..

If you haven't already seen it, johndeere4300 has a good thread on just that:

Thats a good chart that mjp linked. I use 5# ace and 30# oxy for most of my cutting,
1/8" to 1/2". I might jack up to 40# oxy at 1/2" plate. When you light up, make sure your lower oxy knob (by the hoses) is open fully and your ace and upper oxy knobs are off! Then crack and light the ace till you get a good orange flame with a decent 'push'! Then add oxy with the upper oxy valve till you get a nice turquois cone. The way I make sure I'm pretty well set, then, is to push the oxy lever down fully. The cone shouldn't change it's point position that much, and should stay 'crisp'! I agree with the others that a 00 or 0 tip would serve you better. For straight cuts, I always clamp a piece of 1/4" plate about a 1/4" from the cut line, and use is as a guide. Keep the torch tip about 1/8" from the metal your cutting, and drag along the guide piece. Enjoy! ~Scotty
Edit: Ya know, just as an after thought, (I've no exp w/ propane!) I wonder if your cutting success w/ propane is due to the larger nozzle your using?? I'm hoping someone else will chime in! ~S

I agree with Scotty's approach to cutting. I always use the chart to set things up and for chosing tips. I am one of the wierd guys who likes to weld with O/A, occasionally.
For thin stuff I have found that I really like a DHC 2000 (fomerly Henrob 2000) torch rather than using a big torch with small tips . It almost gives you plasma like cuts. I use it for cutting metal for art pieces. Check it out:

Wow that Henrob thing is pretty cool.
I'm one that never changes the tip just leave the same one in there until it can't be cleaned anymore, not even sure what size it is, but use it for all my cutting and heating needs just adjust flame to the specific needs. Didn't even realize there are charts to determine the proper tip for the job, makes sense though especially for production work, for me as a back yard hillbilly doesn't seem to matter.
I do have this special plate cutting tip, that's L shaped and allows you to drag it along on the plate surface, keeping the flame at just the right distance, that does leave a nice clean cut.
As far as you welding with O/A, that's not weird, that's called talented. I've yet to figure that out and I have the equipment, though I must admit I never really gave it an honest attempt. I know an old timer that does a very nice job with a coat hanger!
