Oxy Fuel cutting and Plasma Cutting both have their pros and cons and both are extremely useful. Speed and precision cutting also are benefits of plasma, which typically cuts with minimal slag and can provide smooth cuts with a narrower kerf than that produced by an oxy-fuel torch. Middle and outer fires. As the terms suggest, one torch is used to cut metals, the other is used to join (weld) metals. As a quick comparison, a common propane/air flame burns at about 3,590°F, a propane/oxygen flame burns at about 4,087°F, an oxyhydrogen flame burns at 5,072°F, and an acetylene/oxygen flame burns at about 6,332°F. Oxy-acetylene cutting equipment involves a process where acetylene mixes with inflammable oxygen to cause a flame. An aircraft size torch for small, not tiny, jobs, and a full size torch for big jobs and cutting. If you raise the torch … Even though I have a more than one Plasma Cutter, I use oxyfuel cutting routinely for cutting thick steel for a couple reasons. Invented in 1903 by two Frenchmen, oxy/fuel welding began as a means to fuse metal by combining pure oxygen and a fuel gas such as acetylene. Unfortunately, Acetylene is still the best all purpose gas, but there are viable alternatives, as long as you choose carefully and know what you want to be able to do.

In non-transferred DC torches, the electrodes are inside the body/housing of the torch itself (creating the arc there). Much cleaner cut and less mess or slag to clean up. The plasma flame of a real plasma torch is a few inches long at most; it is to be distinguished from fictional long-range plasma weapons. The center fire is the standard 7 jet Lynx torch. Gas or Oxy-acetylene welding originated in 1903 and is used for soldering or brazing purposes as such. Gas welding was highly-efficient and economical at the same time. If you are planning on using rosebuds or other large tips, remember that you cannot safely draw more than 1/7 of the volume of an acetylene … Oxy-acetylene can weld steel and cast iron and also can do brazing. For my occasional use the bottles last for years and it seems most gas vendors don't worry about just swapping them out. Propane is probably the easiest Acetylene … Based purely on cutting speed, it looks as if plasma is faster than a single oxy-fuel torch all the way up to 2.75 inches. Then, oxygen is streamed onto the metal, burning it away as a metal oxide. As with cutters, plasma welding torches have high speeds and high quality performance for creating pore-free welding seams. Pure oxygen is used to increase the heat generated from the flame. If you cut with acetylene, you normally put the tip of the inner flame cone on the metal (1mm from the plate surface). A plasma torch can be effective for both cutting and welding . Like acetylene… Please make an offer. The most common type of welding torch is the acetylene torch and it uses the a combination of oxygen and gas to develop the heat that will be used to cut the metal.There are several benefits to using an oxy-acetylene welding torch but the most reasonable one is the fact that they are incredibly portable and much less expensive than other equipment that’s used for cutting metal. Propane can like acetylene be used for cutting. The industrial Victor regulators are hands down ,the most unkillable and a Harris torch i like the best for its balance.

An alternative to acetylene is propylene, a byproduct of petroleum refinement or natural gas processing that has a flame temperature of 5,312F (slightly less than acetylene) and a double-bond C3H6. A cutting torch …
