I. Requirements Analysis

In modern industrial and emergency rescue applications, the demand for efficient, multi-functional cutting tools continues to grow. Traditional cutting tools often prove inadequate when confronting complex environments—such as underwater operations and land-based emergency rescues—and cutting tasks involving diverse materials, including high-strength metals and non-metallic composites. The Metal Arc Water-Land Cutter was developed to address this need. Integrating high-temperature metal arc technology, it is designed to meet the demand for rapid, precise, and safe cutting of diverse materials in both terrestrial and underwater environments. This tool finds extensive application across multiple sectors, including industrial manufacturing, marine engineering, and firefighting and rescue operations.

II. Product Features

1. Fully Environment-Adaptable: Its unique design enables this cutter to operate rapidly both on land and underwater, unrestricted by environmental conditions.

2. Wide Material Compatibility: Equipped with an original imported cutting torch and super-heated cutting rod, it can cut and pierce a variety of materials including cast iron, stainless steel, sludge, bulletproof glass, titanium, and aluminum alloys, demonstrating formidable cutting capabilities.

3. High-Efficiency Cutting: The ultra-hot cutting rod generates temperatures exceeding 6000°C during combustion, ensuring rapid completion of drilling, cutting, or chiseling tasks. For instance, cutting through 20mm steel plate takes less than 40 seconds, while severing 25mm diameter rebar underwater requires under 60 seconds.

4. Lightweight and Portable: The entire unit weighs as little as 18 kilograms, with the cutting gun weighing only 1.5 kilograms. This makes it easy to carry and operate on-site, suitable for single-person backpacking operations.

5. Extended Runtime: Equipped with a 10L oxygen cylinder, supporting continuous operation for 216 minutes to meet extended work requirements.

6. Intelligent Adjustment: Oxygen supply pressure can be flexibly adjusted between 0.3 and 0.5 MPa based on the thickness of the cutting material, optimizing cutting results.

III. Application Scenarios

1. Industrial Manufacturing: Used in scenarios such as heavy equipment manufacturing, metal structure dismantling, and scrap metal recycling.

2. Marine Engineering: Rapidly cutting through obstacles during offshore platform maintenance, subsea pipeline repairs, and diving operations.

3. Fire and Rescue: Rapidly cut through metal doors, windows, and vehicle structures during emergency rescues to free trapped individuals.

4. Building Demolition: Handling reinforced concrete structures during demolition projects to enhance construction efficiency.
