[QUOTE="TXBobcat, post: 287981, member: 94"] Like others have said, it's easier to demonstrate than explain, but I'll give it a try. From the beginning: 1). Make sure all valves on the torch and the bottles themselves are turned to the off position. 2). Open acetylene (or whatever gas) cylinder valve about 2 turns. Do not open wide open in case you need to shut down in an emergency. 3). Open oxygen cylinder valve all the way. 4). Open the bottom oxygen valve on the torch (next to the gas) all the way. This allows the gas to go up to the top valve on the torch, which will control the amount of oxygen to blend with the gas. You would only need to use the bottom valve to adjust the oxygen amount when you are using something like a rosebud tip. For cutting, just always leave the bottom oxygen valve wide open. 5). Now I would open the bottom gas valve and the top oxygen valve a turn or so and let the gases come out. While the gas is releasing look at your gauges and adjust the gas to about 5 psi and the oxgen to around 20 psi. Turn gas and top oxygen valves on the torch off after gages are adjusted. 6.) Slightly open the gas valve and use a striker to ignite the torch. Use top oxygen valve on torch to adjust flame. Keep adjusting flame, using only the bottom gas and top oxygen valves until you have the desired amount of heat. 7). When finished cutting, close the gas first and then the oxygen. A clean cutting tip will make things easier also. Make sure all holes in the tip are clean. A '00' tip should work just fine for most things around the farm/ranch. [/QUOTE]
