Lever Type Cutting Torch｜Fast and Precise Flame Control for Industrial Metal Cutting with Lever Operation
Key Takeaways
• Lever Type Cutting Torch enables fast and precise control of cutting oxygen via lever operation
• Supports metal cutting thickness from 2–150 mm, covering a wide range of industrial applications
• Torch head design ensures stable flame, reduces slag, and lowers the risk of backfire
• Multiple models available based on torch head angle, connection type, and fuel gas compatibility
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
Metal cutting using the Oxy-Fuel Cutting process requires precise control of cutting oxygen flow. Lever Type Cutting Torches are designed to allow operators to start and stop cutting instantly, reducing deviation along the cutting line and improving operational safety.
In heavy plate cutting applications, flame control along the cutting path is a critical factor. Delayed torch response can cause burnt edges or excessive slag buildup. The lever mechanism allows rapid activation of cutting oxygen, resulting in smoother and more consistent cut edges.
The Lever Type mechanism uses a dedicated lever to control cutting oxygen independently from the fuel gas valves. This enables fast cutting initiation, uninterrupted flame stability, and is ideal for continuous cutting operations or frequent start–stop tasks.

In fabrication lines that require cutting steel of various thicknesses, selecting the appropriate Lever Type model for the fuel gas and application helps reduce setup time, achieve consistent cut quality, and enhance workplace safety.
When comparing Lever Type with Valve Type torches, Lever Type offers faster response, more precise cutting initiation, and is better suited for continuous cutting operations directly contributing to improved cut quality and long-term scrap reduction.
Summary
Lever Type Cutting Torch is a core tool for metal cutting tasks that demand precision, agility, and safety. Choosing the right model based on fuel gas type and application requirements enhances cut quality and ensures stable production processes.
