Hand torch refers to a portable yet powerful torch used to provide localized heating or light. These tools are essential in many industries because they facilitate detailed work in places that do not allow large equipment. There are several types of hand torches, and each is designed to meet a specific purpose. Here are some of the most common.
The mechanical hand torch has gas, which is mainly oxygen and acetylene. It works through a mechanical process whereby oxygen and acetylene are pumped through individual barrels and mixed in a combustion chamber. Then a spark ignites the mixture, producing a flame. The flame can be controlled to give heating, welding, cutting, or brazing.
A non-chemical hand torch is a mechanical device that operates on a physical process. For instance, a lighter produces a flame through friction, and an electric hands torch generates heat through electric current. These torches do not depend on chemical reactions for their operation but on physical mechanisms. Therefore, they are suitable for small tasks in sectors that do not require intense flame.
Occasionally, the chemical hand torch is more of a variation of the non-chemical one. In this case, chemicals like gas or fuel are used to produce flames through friction and other processes. For instance, lighters use napthalene and hydrogen as chemical hand torch fuel, which produces flames through a friction process. While they are small and often used for specific purposes, torch lighters can help many businesses.
Plasma hand torches use electric arcs to produce flames capable of cutting through thick iron sheets and metal welding. These torches are mostly used in industries that deal with metalworking, vehicle repairs, and construction. Plasma torches are also popular because of their precision and ability to create clean smoke-free cuts. That is why they are most preferred by people in these industries.
Hand torches are valuable tools that have numerous applications in industrial settings, and the materials used to make them significantly affect their performance and durability. The properties of these materials are important, especially if they will come into contact with flames. Below are the most commonly used materials when manufacturing hand torches.
Stainless steel is commonly used in manufacturing hand torches because of its high resistance to extreme temperatures, corrosion, and oxidation. Stainless steel hand torches are ideal for industries that deal with chemicals and high humidity, such as pharmaceuticals, food processing, and marine. The longevity of stainless steel torches reduces the long-term costs associated with tool replacement.
Brass is an alloy of copper and zinc, and it is commonly used to make hand torches due to its excellent mechanical properties and resistance to corrosion. The copper-zinc alloy is durable, easy to machine, and highly resistant to oxidation, making it suitable for applications where the torches are exposed to harsh environmental conditions.
Though not as strong as stainless steel, hand torches made of Aluminum alloys are lighter and still have decent strength and corrosion resistance. These features make aluminum torches suitable for the medical and electronic industries, where mobility and ease of use are important. Moreover, aluminum's non-toxic properties make it safe for use in industries that deal with sensitive biomedical components.
Manufacturers use high-temperature alloys such as nickel-based alloys in making hand torches for applications in extreme environments. These materials maintain their strength and hardness at elevated temperatures. Thus, they are ideal for aerospace and advanced manufacturing industries. Companies in these industries benefit from enhanced performance and safety due to the use of high-temperature torches.
Hand torches are used in many industries for different purposes. That is why understanding how hand torches are used in these commercial setups will help buyers make the right decision when purchasing these items in bulk. Below are the most common scenarios in which hand torches are widely used.
In this space, they use hand torches during welding, metal cutting, and brazing. Hand torches provide precision and control when doing these activities. Most people in this industry prefer a plasma hand torch because it produces clean cuts that do not require further finishing. Furthermore, using a hand torch helps maintain the integrity of surrounding materials.
Vehicle mechanics and repair experts use hand torches to conduct soldering electrical system repairs and welding vehicle parts. They use mechanical hand torches because they are portable and precise. These features enable the technicians to conduct detailed repairs in confined spaces. Also, the torch's versatility allows the workers to perform various repairs with just one tool.
People in the jewelry business use hand torches to carry out intricate soldering, gold and silver jewelry manipulation, and gemstone treatment. They mostly prefer using a chemical hand torch due to its precision, which is necessary when soldering small metal pieces. These torches have adjustable flame control, allowing jewelers to work on their delicate pieces safely.
In the construction industry, hand torches are primarily used during roofing operations, metal work, and even in some demolition activities. For example, acetylene torch welding is popular among construction workers. It enables them to weld metal structures and repair equipment on the work sites. Because of their mobility and efficiency, handheld torches make them a necessary tool in this industry.
Here are a few things buyers should consider when selecting a hand torch for their clients.
Fuel Type
Buyers should advise the businesses they work with to consider which kind of fuel their hand torch will use. For instance, acetylene torches provide high temperatures and are thus ideal for industrial welding and metal cutting. On the other hand, butane torches are designed for more delicate work. These include jewelry repairs and other small detail jobs.
Ignition Type
Handtorches with piezoelectric ignition are preferred because they provide an easy and quick ignition, thus enhancing their efficiency. But those with a manual ignition are less efficient because they will require extra time and additional steps to get them to light up. So, buyers should consider their clients' needs and how efficient the torches will be for the businesses.
Adjustable flame
Torches with flame control are ideal because they allow users to adjust the size and intensity of the flames depending on their task. This feature enables greater flexibility, especially for people who work with different materials that need different flame sizes. For instance, softer metals require low flames, while harder ones need high flame.
Materials
Handtorches manufacturers make them with different materials having various benefits. For example, brass torches are durable and have good corrosion resistance. However, they are heavier than other options. Besides, aluminum torches are lighter and easier to handle, although they may not be as durable as brass ones. Buyers should consider which material will best suit their clients' operational needs.
Users should always put on protective gear, such as safety goggles, gloves, and a face shield, to protect themselves from possible sparks, flames, or sharp metal pieces. They have to work in well-ventilated spaces to avoid inhaling toxic smoke and gas. Additionally, they have to ensure that the torch has a proper shut-off mechanism and keep flammable substances at least 5 meters away from where they will be working.
Mechanical hand torches are more efficient than others. This is because they generate a high-temperature flame, which makes them ideal for tasks that need intense heat, such as cutting and welding metals. They also have a concentrated flame, which means the heat will be directed to a small area, reducing waste.
People should always keep their handtorches' wear parts, such as gaskets and nozzles, updated to maintain good condition. They should also clean the torch after every use to remove any debris or buildup. This will help avoid clogs and ensure the torch works well. Additionally, manufacturers recommend people keep their torches in a cool, dry place so that its components do not get damaged or wear out.
Yes, automotive technicians usually use handtorches to solder wiring systems. Wiring repairs require a precise application of heat to avoid damaging the surrounding insulation or components. A handtorch allows technicians to easily control the flame and deliver the needed heat without overheating nearby elements.
