Went today and got a bottle of oxygen, 50' of T hose, flash arrestors, and a couple of Victor propane tips.
Got it home and put it together. Tested with soapy water. Everything looks good.
First thing I noticed is when you spark the gas, there is no black smoke to indicate the right amount coming out. The color of the gas is very different, too. Adjusted it to about where I thought it should be. Adjusted the oxygen so that the points of the blue flames are the same with the O2 valve open and when the handle is depressed. The shape of the blue flames is different from that of acetylene, rather like a loop than a cone.
Am I close? Any sites you can direct me to with pictures that will help me get the mix right.
I'm using 3-6# on propane, and 20-25# on oxygen with a size 0 cutting tip, according to the chart given me.
Got it on about four and twenty, actually.
I was told by the counter man that propane takes longer to heat up, other than that, it's about the same.
Any pointers would be appreciated.
I've used acetylene all my life, but didn't want to fork out $250 more for another bottle when I have about eight propane bottles. The charge was the same for any size bottle, so I got the big one, K, IIRC. Will watch for a larger propane bottle now.
Got some 7018AC 3/32 and 1/8 and am ready to buzz up some stuff for a neighbor. Looks like I'm welding again after a long pause. Still got my MIG, a Lincoln 175SP+. It's time to make some "stuff". And get a DC machine, IdealArc 250, I'm thinking.
TIA
