Cutting Torch Buying Guide: Everything You Need to Know

Cutting torches are an essential tool for any metalworker or welder. These tools allow you to effortlessly cut through metal with accuracy and precision, making them an invaluable asset to any workshop or job site. However, with so many different cutting torches available on the market, it can be challenging to determine which one is right for your needs. This article will provide you with a comprehensive cutting torch buying guide to help you make an informed decision when purchasing your next cutting torch.

Types of Cutting Torches

The first thing to consider when purchasing a cutting torch is the type of cutting torch that you need. There are several types of cutting torches available, including:

• Straight Handle Cutting Torch
• Medium Duty Cutting Torch
• Heavy Duty Cutting Torch
• Track Cutting Torch
• Scarfing Torch

Straight Handle Cutting Torch

Straight handle cutting torches are the most basic cutting torch and are ideal for small-scale cutting projects. These torches are lightweight and easy to maneuver, making them perfect for hobbyists or DIY enthusiasts who need to cut metal occasionally. They usually can cut up to 1.5 inches of metal.

Medium Duty Cutting Torch

Medium duty cutting torches can cut through thicker metals than straight handle cutting torches. They are also more durable and can withstand heavy use on a daily basis. Medium duty torches can cut up to 3 inches of metal.

Heavy Duty Cutting Torch

Heavy duty cutting torches are designed for use in heavy-duty industrial applications or large-scale cutting projects. These torches are made from durable materials and can cut through even the thickest metals easily, making them ideal for construction, fabrication, and repair projects. Heavy-duty cutting torches can cut up to 12 inches of metal.

Track Cutting Torch

Track cutting torches are used for cutting metals on a fixed track or a straight line. They come with an adjustable guide and can cut thicker metals up to 6 inches with ease.

Scarfing Torch

Scarfing torches are a type of cutting torch designed for preparing steel for welding. They are used for removing unwanted sections of steel plate or cutting bevels, a process that is necessary to ensure the highest quality welds. Scarfing torches are commonly used in the construction and fabrication of ships and offshore structures.

Fuel Types

The next thing to consider is the fuel type that you need for your cutting torch. There are two primary fuel types, including:

• Oxy-fuel torches
• Plasma cutters

Oxy-fuel Torches

Oxy-fuel torches use a mixture of oxygen and fuel gases (such as acetylene, propane or propylene) that is ignited to create a flame hot enough to melt or burn through metal. This type of cutting torch is suitable for cutting and welding applications on metals like steel and aluminum.

Plasma Cutters

Plasma cutters use a high-temperature plasma arc to melt through metal. The plasma arc is created by passing an electric current through a gas that is blown through a nozzle. Plasma cutters are faster and more precise than oxy-fuel torches, making them ideal for cutting intricate shapes in metals like stainless steel and aluminum.

Cutting Torch Features

There are several important features to consider when purchasing a cutting torch. These features include:

• Cutting capacity
• Fuel efficiency
• Tip compatibility
• Torch angle
• Design
• Weight and size
• Portability
• Durability

Cutting Capacity

Cutting capacity refers to the maximum thickness of the metal that the cutting torch can cut through. The cutting capacity of a torch depends on the model and fuel type. For example, an oxy-fuel torch may have a cutting capacity of up to 12 inches, while a plasma cutter may only have a cutting capacity of up to 2 inches. Consider the cutting capacity you will need based on the type of projects you will be working on.

Fuel Efficiency

Fuel efficiency is an important consideration when purchasing a cutting torch, as it affects the overall cost of operation. Oxy-fuel torches tend to be less fuel-efficient compared to plasma cutters. Therefore, you may want to consider a plasma cutter if you need to cut through a lot of metal regularly.

Tip Compatibility

The type of tip that a cutting torch has determines the cutting depth and width. Most cutting torches come with a set of interchangeable tips that allow you to adjust the torch's cutting power based on the project's needs. Ensure that the tips that come with the cutting torch are compatible with the type of metal you want to cut.

Torch Angle

The torch angle is the degree to which the cutting torch is tipped downward. The torch angle affects the shape of the cutting groove, and a more angled torch will create a wider but less clean cut, while a less angled torch will create a narrower but cleaner cut. Choose the torch angle that will give you the right balance between cutting speed and accuracy based on your project's requirements.

Design

Cutting torches come in various designs, including straight, angled, or curved. Straight cutting torches are ideal for straight-line cuts or vertical cuts, while angled or curved cutting torches provide greater maneuverability and can be used for more intricate cutting tasks. Choose a design based on the type of metalwork you are doing.

Weight and Size

The weight and size of a cutting torch can affect the level of precision and control you have over the tool when in use. Choosing a lightweight cutting torch can provide you with greater control over the tool, making it easier to make accurate cuts. However, a smaller torch may not be as powerful as a larger torch, which may affect cutting efficiency. Consider the weight and size that will be most comfortable for you to use based on the type of metalwork you are doing.

Portability

Portability is an important consideration if you will be using your cutting torch in different locations. Ensure that the cutting torch is easy to move around and can fit in your vehicle or work area without taking up too much space.

Durability

The durability of a cutting torch is essential, particularly if you will be using the torch frequently or in industrial settings. Choose a cutting torch made from high-quality materials that can withstand heavy usage and regular wear and tear.

Cutting Torch Safety

Cutting torches can be dangerous tools if not used properly. Therefore, it's essential to take safety precautions when using a cutting torch, including:

• Wearing protective clothing, including safety glasses, gloves, and a welding helmet
• Ensuring that the work area is adequately ventilated
• Keeping the cutting torch away from flammable materials and objects
• Checking the fuel tanks and hoses for leaks before turning on the torch

Conclusion

Purchasing the right cutting torch is essential for any metalworker or welder. Understanding the different types of cutting torches, fuel types, and features available can help you make an informed decision when purchasing a cutting torch. Consider the type of projects you will be working on and the cutting capacity you will need to select the right cutting torch for your needs. Always prioritize safety when using cutting torches to ensure that you can complete your projects safely and efficiently.
