oxy lpg conversion
hey guys, i've been told my acetylene set can be used on lpg by just changing hoses and tips but can use the same regulator. i tried to insert the acetylene regulator into a standard 9kg barbeque gas bottle, as i was told you could do, and it only went in a couple fof threads before the reg got super hard to turn and would start to strip the threeads. are they different threads? is there an adaptor for this?

acetylene regulators have a left hand thread, you need a lpg regulator.

You might want to do a bit more research into this, mixing oxy/acet regulators with LPG using OXY/Acetylene equipment can be quite explosive as it isn't the same. You need to use regulators specified for OXY/LPG otherwise you'll get very explosive results.

It was a decade or so I changed over , but I just used the threaded part from an old 9kg LPG bottle regulator to replace the threaded part of my aceteleen gauge.Easy as that .Same gauge , same settings, just swap the threaded collar for one with the LPG thread.
.
The same brazing/heating tips can be used with a slight cup drilled in the end . Same hose can be used but u will need a special cutting tip for your cutter.

I think that might be an urban myth..They run at similar pressures but the threads are slightly different in some way that I have not researched... Originally Posted by DJ's Timber

I picked up a Harris regulator for $115 from my local welding shop...It was cheaper then ebay or online....
