Setting Up a Welding Torch for Wire Sculptures

Video Transcript

I'm Mark Kooy here with Expert Village and we are going to be talking about wire sculpture and braising techniques and tools. We are going talk a little bit about the torch set up and using oxi settling. That really does refer to the two things that make it work. The settling gas which comes out of the red hose and the oxygen that is usually in a green or black hose. We work off these two tanks. This shorter but chubbier one is the settling tank and the oxygen tank is the blue one and often times it will be green. In this particular shop, we run it through a manifold so we turn the tanks on a quarter turn each one and we adjust our torch itself the pressure coming to with the regulators in the booths. Knowing that this is tghe gas because it has the red hose hooked to it and we can also see that the gage on here is in different increments; increments of 5 compared to the oxygen in increments of 20 or sometimes 10. So we are going to turn our gas and the way that these diaphragm valves work is as we turn in, it presses on and squeezes the diaphragm open and allows the gas to come in. So you will feel this get tight instead of loose like water. it will get tight and you bring it in to about 5 pounds of pressure. With the oxygen the same thing, we are turning it in and it opens up the valve and we are going to turn it up to about 10. So 5 for the gas and 10 for the oxygen. I tend to want to get in the habit of always what we kind of do the gas on and gas off first because that is more important when we get to the torch turning on and adjusting the torch. But adjusting these guys, it is always a good practice to turn the gas on and off first that way you are always leaving the lines and torch charged with oxygen and not the gas.
