Oxy-fuel cutting and flame

The French leader in Oxy-fuel cutting and flame technology, Le Lorrain offers a wide range of French-made torches: welding torches (type S0, S1), cutting torches (Top Naval, DH1, HP1), and heating torches (Oxy-acetylene or Oxy-propane). They are available with or without ARPF (flashback arrestors, flame arrestors, or check valves), with 90°, 120°, or 180° heads, equipped with a trigger or valves, with or without shielding. Finely crafted, they come with a 2-year warranty.

For the entire range of LE LORRAIN torches, quality and durability are emphasized. This extensive line includes welding torches, cutting torches, low-pressure and high-pressure torches. LE LORRAIN low-pressure torches are available in a variety of models to suit the user: oxygen-acetylene or oxygen-propane/LPG, simply install the appropriate cutting head. However, for experienced professionals, a low-pressure torch is recommended.

Our cutting torches are designed for optimal performance, whether used in industrial or artisanal applications. The Top Naval, DH1, and HP1 models are renowned for their durability and ease of use. In addition, our heating torches, operating with oxygen and acetylene or propane, are perfect for applications requiring intense heat and precise control.

Each LE LORRAIN torch is designed to offer maximum safety, with built-in safety devices such as flashback arrestors and flame arrestors. Our products are rigorously tested to ensure they meet the strictest safety standards. Thanks to our commitment to quality, LE LORRAIN is synonymous with reliability and performance in the field of oxy-fuel cutting and flame technology.

Explore our full range and choose the torch that best suits your professional needs. Whether you are an artisan, an industrial worker, or an experienced professional, you will find reliable, robust, and high-performance products at LE LORRAIN, supporting all your welding and cutting tasks.

High-pressure cutting torches

LE LORRAIN high-pressure cutting torches are especially recommended for users working in tough conditions or for less experienced users. The heating gas mixture occurs in the cutting head. It is advisable to choose the cutting head according to the gases used and the thickness to be cut.

Oxy-acetylene torch

Oxy-acetylene torches using the oxy-fuel cutting method are among the most popular tools for separating low-alloy and low-carbon metals. The metal cutting process involves heating the material to a temperature at which it burns upon contact with the torch and vaporizes as metal oxide. This effect is only possible through the use of properly constructed torches that can mix oxygen with specific proportions of fuel gas.

Fuel gases can include materials such as acetylene and propane-butane. Due to its ability to reach higher temperatures more quickly and maintain them longer, acetylene cutting is a highly efficient method. Moreover, significant advantages of oxy-acetylene torches include their mobility—allowing for cutting at various angles—their ability to deliver high-quality cuts even on thick sheets, and the potential to mechanize cutting processes with their use. This metal processing method is applied across many industries—from small workshops to large production facilities. Thanks to its versatility, oxy-fuel cutting can be used for machining cast iron, brass, bronze, steel, and other metal alloys, as well as for heating, burning, and brazing.

How does an oxygen-acetylene torch work?

The essence of gas welding lies in heating the material to a temperature at which it is altered by an oxygen-acetylene flame through a change in its physical state. This method allows not only for the separation of steel components up to 300 mm thick, but also for their permanent joining. The results and cutting quality vary depending on the choice of torch. The smaller the torch, the finer the flame, and the greater the cutting precision. Universal torches are used for both cutting and welding. Naturally, not all metals can be processed using oxy-fuel cutting. Sensitive materials include:

- Iron

- Brass

- Bronze

- Cast iron

- Titanium

- Tungsten

Oxy-acetylene burners are also ideal for machining structural steels, low-alloy steels, low-carbon steels, and rust-covered metals.

Where is the oxygen-acetylene torch used?

It is the foundation of all work in the field of machining, cutting, and welding various metal alloys. Due to its versatility and the ability to adapt components such as torch size, oxy-fuel cutting finds many applications not only in large companies but also in small businesses and workshops. There is a demand for this type of service wherever there is a need to precisely and efficiently adapt even thicker metal components to the requirements of a specific industry or service.
