The Arzell C+ Torch: Redefining Plasma Performance

As coating requirements become more demanding, traditional thermal spray equipment has reached its limits. Carbide coatings rely on high-velocity combustion (HVOF), while thermal barrier coatings need high-temperature plasma systems. But as regulations tighten and performance expectations rise, the industry needs new solutions that go beyond legacy torch designs.

The Challenge with Legacy Cascade Torches
Cascade-style plasma torches improved process stability by constraining the arc, reducing fluctuations from power supply dynamics. However, this also created new challenges—greater heat loading on the nozzle and limited gas compatibility—restricting performance and efficiency.

The Arzell C+ Advantage
The Arzell C+ Torch was engineered to overcome these limitations. Designed for both high-power and high-pressure applications, it delivers the broadest performance range of any cascade-style torch. Built with a robust, patented design, the C+ provides unmatched scalability and reliability in production environments.

Key Innovations and Benefits

Wider Operating Range

The C+ supports a broader spectrum of gas mixes, including low-density molecular gases that were previously unusable in cascade systems. Operators can fine-tune temperature and velocity across the entire coating spectrum—from ceramics to carbides—to achieve optimal results for each material.

Higher Plasma Efficiency

The C+ produces higher-energy plasma (greater enthalpy) without a proportional increase in power. This means superior thermal transfer to powder particles and better coating quality at lower
operating costs.

Better Thermal and Material Efficiency

Operating in high-energy regimes, the C+ torch consistently delivers:

  • Lower gas consumption
  • Reduced heat loss to cooling water (improved thermal efficiency)
  • Higher deposition efficiency and coating consistency

Rethinking Performance Metrics

Power alone doesn’t define coating performance. True efficiency comes from how effectively that power is used. The C+ Torch is the first cascade torch to efficiently use molecular primary gases to produce higher-enthalpy plasma, unlocking new levels of coating quality and process control.

A Future-Ready Solution

The Arzell C+ Torch represents a major step forward in thermal spray technology. Its versatility, efficiency, and expanded gas compatibility make it ideal for both R&D and production environments. As the industry pushes for higher performance under stricter conditions, the C+ is proving to be the next-generation solution that keeps operators ahead of the curve
