Praxair Surface Technologies, Inc. and TAFA Incorporated is a world leader in thermal spray equipment, materials and coatings technology. As a primary contributor to the development and application of plasma spray with equipment and coatings routinely used by the aircraft engine industry for OEM and repair coatings for over 45 years, Praxair and TAFA has designed a complete family of products reflecting years of equipment engineering and coatings expertise. Our plasma product line is certain to include a system that meets your specific quality, productivity, versatility and economic needs. We recognize that the selection of a new plasma spray system is just the initial step. That′ s why Praxair and TAFA continues to develop and perfect new plasma powders and coatings to help push thermal spray technology toward an exciting generation of wear, oxidation and corrosion-resistant applications. We dedicate talented engineers to team with you to develop materials, processes and coating solutions that expand the market for cost-effective thermal spray applications. Let us work with you to select the best plasma spray system and put it to work to maximize your output and returns.

One of the key advantages of the Model SG-100 gun is its ability to adapt to the Model 2086A ID extension, shown applying a TBC on an aircraft burner can.

Integrated Systems
In order to produce superb plasma-sprayed coatings with a wide variety of materials, plasma spray equipment must perform consistently, whether the energy level is 15 or 80 kW. To provide consistent control over the complete range of plasma spray systems and power levels, Praxair and TAFA offers three plasma controller options: (1) manual, single-process with critical orifice control; (2) computerized, single-process with mass-flow control; and (3) computerized, multi-process, with mass-flow control.

Whether you need simple, reliable plasma spray equipment or a sophisticated, robust computerized system, Praxair and TAFA has a solution for you. We take pride in offering a range of engineered systems; each includes the necessary safety engineered, plug and play modular components including power supply, arc starter, control console, powder feeder(s) and spray gun. This allows you to get up and running quickly.

Committed Resources
The decades of excellent performance provided by our plasma systems, including critical aircraft engine applications, are a reflection of our commitment and expertise in the field of Thermal Spray.Praxair and TAFA′ s plasma systems are designed to produce quality coatings using our Model SG-100 gun, other outstanding plasma guns produced by us or most other manufacturers′ plasma guns.

We can offer a complete plasma system that fits most requirements. Importantly, we support our hardware with unparalleled technical service and applications assistance, along with one of the most capable powder operations in the thermal spray industry. Praxair and TAFA′ s equipment options, powder quality and selection, and coatings knowhow offer you the best value for a total plasma coating system.

Integrated Know-How
Our pioneering use of argon as the primary plasma gas gives:
•  Easier/simpler ignition and startup
•  An arc larger in diameter and "softer" than diatomic gas arc
•  Less substrate heating due to shorter effluent plume
•  Quieter operation; more stable arc region
•  More consistent performance
•  Cleaner coatings

Combine this with first-rate engineering backup, coating expertise and world-class powder and you can be assured of consistent reliable coatings.Add it up and you will agree: Praxair and TAFA has the right plasma solution to meet your needs.

Manual/Economical (Model 3710)
The economy unit, suitable for low to medium production rates.

Closed-Loop (Model 7700 UPC)
The computerized mass flow-based "universal" controller that operates most plasma guns.

Multi-Process Controller (GTS)
For unparalleled control of multiple thermal spray processes, Praxair and TAFA offers the advanced Global Tasking System (GTS) closed-loop, computerized controller. The GTS can operate all spray systems including combustion, arc wire, plasma and HVOF.

Each plasma spray system includes everything you need to produce outstanding coatings, whether your applications require a simple unit with a Model SG-100 gun (left) or a sophisticated, fully integratable Global Tasking System (GTS) (above).
