How to set up an Acetylene Torch for Cutting?

Acetylene Torches Oxy - cut through steel faster than most other cuts tools.Igniting. Acetylene flame.Oxygen heat stability of the flame temperature and speed of the gas from the torch flame from the torch tip.The hot metal. When you increase the flow of oxygen through the heated metal. steel.Properly. Set the cutting flame to cut clean, and keep you safe during the cutting process.

Acetylene Torch for Cutting

Instructions
1.Remove the protector caps from the bottles of oxygen and acetylene.Quickly open and close the valve handles located at the top of each bottle to blow contaminants from the valves.

2.Thread the oxygen regulator (green hose) of the torch onto the valve of the oxygen bottle.Thread the acetylene regulator (red hose) to the acetylene valve.Tighten the regulator nuts with an adjustable wrench.

3.Fully close the gas control knobs located at the base of the torch head.

4.Turn the acetylene valve handle a quarter turn.Adjust the regulator to flow the amount of gas recommended by the torch head manufacturer.Slowly open the valve located at the top of the oxygen tank.Adjust the flow rate of the oxygen to the recommended settings.

5.Turn the acetylene control knob located at the base of the torch head slightly.Place a friction striker in the stream of acetylene gas.Push the handle of the striker to light the torch.Turn the acetylene knob until the flame glows bright orange and does not jump from the torch tip.

6.Slowly open the oxygen control knob until the flame glows a bright blue with a well defined set of center flames.

7.Depress the oxygen level located near the middle of the torch head.The velocity of the flame will increase substantially without causing the flame to go out.Turn off the oxygen and reignite the flame if it goes out before you begin cutting with the torch head.

Plasma Cutting Systems

Plasma is the fourth state of matter. It consists of ions, positively charged atoms, negatively charged ions (electrons) and positively charged molecules. It also contains neutrally charged atoms. Plasma is a good conductor of electricity. Plasma exists at very high temperatures and is used by plasma cutting systems to cut metals.

Plasma Cutting Systems

Let us see how plasma cutting systems work? A gas is released through a very narrow opening, thereby increasing its high pressure. Before the gas escapes, an electrode is placed in its way that passes an electrical current through the gas. The gas atoms on being stimulated by the electric current produce positively and negatively charged ions. These ions collide with each other and the rest of the gas atoms to produce more ions. In no time, the gas reaches a superheated state or plasma.

Plasma Cutting Machine

Plasma cutting systems are nothing but an electrical circuit that have an electrode acting as a negative terminal (cathode), and the metal sheet to cut, acting as the positive terminal (anode). The plasma jet is attracted towards the metal sheet and at this point, in the operation, can focus as much as 30,000 degrees Fahrenheit or 16,648 degrees Celsius of heat on the metal sheet and melts it. The narrow opening of the nozzle increases the pressure exerted by the gas which also blows away the melted metal, thereby aiding the cutting of the metal sheet. The plasma arc is kept thin and controlled with the help of shield gases.

A plasma cutter is provided with channels to release shield gases which exert pressure and control the plasma arc and keep the plasma jet directed on the metal sheet. Inert or semi-inert gases are used as shield gases to shield the area, where the plasma arc or jet touches the metal. The plasma cutter is also known as a plasma torch. Plasma cutting systems are available as manual and computer-controlled. Let's take a brief look at the latter type.
