Manual flame cutting machines

Types of manual flame cutting machines

Manual flame cutting machines use oxygen and fuel gas to cut metal. Operators can control the cut manually with this equipment. Even though modern technologies have produced numerous cutting methods and machines, manual flame cutting remains one of the cheapest ways to cut metal. There are different types of manual flame-cutting devices.

• OFFHAND CUTTING TORCHES

  Offhand cutting torches allow operators to manually control and direct the flame when cutting metal. They are typically lightweight and portable, designed for use with various fuel gases.

• HAND-HELD CUTTING TORCHES

  Hand-held flame cutting torches are tools used to cut metal with a controlled flame. They are typically used in conjunction with fuel gases that are stored in pressurized tanks and mixed with oxygen to create a flame that's used for cutting.

• MANUAL CUTTING DEVICES

  Manual cutting devices are tools operated primarily by hand without the use of electric or hydraulic assistance. They are often used for cutting various materials.

• SLAB & GRADE SAWS

  In manual flame cutting, slab and grade saws refer to specific types of cutting techniques or approaches used to make desired cuts on materials such as steel or metal using a flame cutting torch. Flame cutting refers to the process of using a flame cutting torch to cut through various types of materials. It involves using a specialized weapon that directs a high-temperature flame on the material to create cuts in desired shapes and patterns.

• TRACK CUTTERS

  Track cutters in manual flame cutting refer to the apparatus or system that allows for controlled and guided cutting of materials using a flame. It typically consists of a track or rail system along which a flame cutting torch is mounted or suspended. The track enables the torch to move smoothly and steadily along a predetermined path, ensuring accurate and consistent cuts.

Specifications & Maintenance

• Cutter capacity:

  The cutting thickness and diameter that the flame cutter machine can handle varies depending on the machine model and type. For example, a features flame cutting machine may have a capacity to cut thicknesses up to 6-12 inches and diameters of 40-60 inches.

• Cutting speed:

  The speed at which the flame cutter can make cuts is given in millimeters per minute or inches per minute. The cutting speed for flame cutting machines can vary depending on the type of metal being cut and its thickness. For example, a flame cutting machine can achieve a cutting speed of 30-80mm/min on ordinary carbon steel.

• Cutting accuracy:

  Flame cutting accuracy refers to the precision of cuts made by the cutter and is usually represented by values such as mm or inches. Flame cutting accuracy indicates the maximum and minimum measurements of the cut with respect to the material being cut. The cutting accuracy of a flame cutting machine typically ranges from +/-1mm to +/-3mm.

• Cutting method:

  Cutting methods include straight, oblique, arc, circular, mariner cut, bevel, and other types of cuts. Some flame cutting machines can also do complex cut types with the help of digitally controlled systems.

Flame cutting machines require regular maintenance to ensure they operate safely and efficiently. Here are some maintenance tips for flame cutting machines:

• Before starting the machine for the day, check whether the cutting torch has been damaged or burned out and whether there are any kinks in the air and fuel gas pipes. Check whether the fastening parts are loose and whether the work environment is bright and ventilated. These things can help to ensure safe production.
• Cleaning: Keeping the machine clean is important for flame cutters. Regularly remove the cutting torch and clean it with gasoline and detergent to maintain its normal operation. Also, clean up the debris and dirt on the work platform of the machine to keep it tidy and organized.
• Lubrication: Maintain machine parts' flexibility and ease of use by applying appropriate lubricating oil to the moving parts at regular intervals, such as the guide rails, gears, and bearings.
• Regular inspection of the machine is required to determine whether the power supply and air compressor are functioning properly. Additionally, promptly inspect and repair any abnormal noises, vibrations, or malfunctions.
• Keep flame cutting tools like flame cutting machine torch tools out of corrosion and dampness. Also, avoid exposing them to direct sunlight or high temperatures for an extended time. Store these tools in a dry and ventilated area.

Scenarios

• Iron cutting

  Manual flame cutting machines have wide applications in various metal industries. These machines can cut different metals with varied thicknesses, such as carbon steel, alloy steel, pig iron, channel steel, copper, and more. Flame cutting machines obtain their energy from combustion gas and oxygen, resulting in a high-temperature flame that can easily melt and vaporize metals. For this reason, metal workers can use manual flame cutting machines to conduct pipelines, manufacture ship hulls, bridge construction, metal frame fabrication, and other metal processing industries.

• Thick material cutting

  Manual flame cutting machines excel at cutting through thick and heavy materials, which pose great challenges to other cutting methods and machines. Their ability to adapt to varying thicknesses and produce high heat makes them a great option for even the thickest materials. There are two ways the machines achieve this. First, operators can control the cutting speed, allowing slow cutting for maximum heat concentration to penetrate thick sections. Second, the gas mixture can be adjusted to increase the flame's intensity and heat output.

• Curved and irregular cutting

  Due to the nature of flame cutting, when the operator controls the direction of the cut by moving the torch, achieving curved and irregular shapes makes the cutting machine very adaptable. This ability works well in fabrication industries where irregular and curved shapes are required. Manual flame cutting machines can help create molds and designs and assist in metal repair.

• Offshore and pipeline industries

  Manual flame cutting machines are great tools for the offshore and pipeline industries. In the offshore industry, workers often face tough environmental conditions, such as extreme sea, cold, heat, or humidity. The great portability of flame cutting machines means metal workers can use them to cut metals in areas where electricity may not be accessible, such as in floating platforms, deep-sea valves, ship hulls, and other ship construction scenarios. In the pipeline industry, the high temperature of the flame from the flame cutting machine melts the pipe's metal. This allows the machine to cut through a large number of pipes quickly and efficiently without causing the pipe to bend.

How to choose manual flame cutting machines

For business buyers looking to purchase a manual gas cutting machine in bulk, there are a few factors they need to consider.

• Quality and safety features

  When buying manual flame cutting machines for resale, buyers need to ensure they have quality and safety features. Look for things like overheat protection, pressure regulators, and anti-backfire devices. The quality and safety features of the cutting torch user can impact the resale value of the product.

• Product variety

  When buying in bulk, it is important to offer customers a variety of options to choose from. Consider buying manual cutting machines of different styles and sizes to meet diverse customer needs. Explore the suppliers catalog and negotiate for more product variety.
