Everyone has to start somewhere when trying to learn how to use a cutting torch, specifically an Airco model. If you’ve got some background or knowledge when it comes to operating these torches, and you’re in a rush to make a fast check on what else you need to keep in mind before welding, then you can apply our three quick tips. In this article, we will discuss the main parts of an Airco cutting torch, how to protect yourself during the cutting process, and points to always remember when skimming through an Airco cutting torch for sale.
When your objective is to be an expert in welding, one of the first things you would prioritize is mastering your Airco cutting torch parts. Like the regular oxy-acetylene cutting torch, an Airco cutting torch has four main parts: the handle, torch tip, valves, and mixing chamber. If you assembled your torch from scratch, then you more or less have heard of these basic components.
The handle doesn’t only offer a solid grip for torch operators but also functions as a passageway compatible with any flow of fuel gases. On the upper part of the handle, you will find its mixing chamber; this explains why the handle seems to “overheat,” which compels you to grab the welding gloves. When combustion occurs, the handle lets oxygen and acetylene mix and react at the base of the chamber.
If you notice that your handle gets hot within 30 seconds, there must be something wrong with the cutting torch. Remember that it takes a while until it gets scorching, so in a 30-second duration, your handle should still be cool.
There are two kinds of valves: an oxygen valve and an acetylene valve. This part of the cutting torch is responsible for regulating, directing, and controlling the flow of oxygen or acetylene. The operator just has to manage how they open, close, or partially shut the passageway to manipulate the amount of oxygen or acetylene that exits the torch. All it takes is to twist and turn the valve fitting.
An acetylene valve is usually color-coded in red, matching the color of its hose, while the oxygen valve and its respective hose are commonly color-coded in green. In the beginning, the oxygen valve should be tightly sealed, then controlled based on the low-pressure gauge during the cutting phase. Before you allow acetylene to exit your cutting torch, take note that it is an unstable and dangerous chemical that could explode when mishandled.
You can easily determine a cutting torch’s mixing chamber by locating it inside the body where the primary chemical reactions transpire. The oxygen valve and acetylene valve are connected to the mixing chamber, which is made up of two stainless steel or brass tubes.
The mixing chamber is then linked to the torch tip, where the oxy-acetylene is released with a lever. For you to understand the size and style of a mixing chamber, you will need to measure the size of the entire cutting torch. It may surprise you, but some manufacturing companies integrate the mixing chamber within the torch tube itself. To be extra sure of your Airco cutting torch model’s anatomy, you can refer to the provided manual.
When dealing with Airco cutting torch tips, it is important to be very cautious since this is the site where oxy-acetylene is ready to burn and cut across metal with one push of the trigger. If you are wondering: all torch tips are different, and the reason for that is because each torch tip accommodates a particular fuel gas with a varied set of chemical attributes. The accommodation manifests in granting the welding operator to achieve the same cutting results, only with a different kind of fuel-powered torch.
After you’ve mastered the basic parts of an Airco cutting torch, our next tip for you is to grasp the significance of personal protective equipment (PPE). Beyond learning how to join two pieces of metal or cut a piece into equal halves, it is just as crucial to know the correct safety equipment. Below are some safety gears that you need to wear:
Have a clear vision of what you are cutting without worrying about sparks and open flames getting to your hair, skin, or face. Welding helmets and hoods are effective PPEs because of their comprehensive auto-darkening features together with a state of the art LCD lens technology and eyesight protection.
For frontal protection, welding goggles and face shields are integrated with comfortable, lightweight protection for your face. This is ideal for various kinds of welding environments since your head protection is portable and easy to wear.
Protect your hands from spatter, sparks, burns, and bruises during the cutting processes. To match your welding tool, you need to have welding gloves that complement its function, whether it’s premium MIG, TIG, or Stick welding gloves. Its purpose is to get your tasks finished and provide you with maximum protection and security.
Eradicate problems and inconveniences related to dust, debris, and perspiration getting into your eyes with some welding goggles or glasses. These are styled in such a way that you would acquire an optical buffer through their shatterproof polycarbonate lenses.
Aside from tight-fitting outfits, welding apparels serve as an extra layer of protection. Your selection for this added defense consists of welding jackets, aprons, caps, and sleeves to fully shield your body against any welding hazards at work.
