A true classic of the arc spray line which features an air-driven "pull" 350-amp gun and a control that is simple to operate, the 8830 has become a proven economical and reliable standard of excellence with thousands of applications worldwide.

Adaptable to any spray environment, the 8835 features an electric motor "pull" 350-amp gun and modular unbundled control technology. The PLC controls can be used in either automatic or manual mode, and the gun is flexible enough to be handheld or robotically mounted.

The 9935 is a robust, machine mounted or hand-held gun combining the proven, rugged wire drive of the 8835, with a reliable DC servo motor, the high volume air flow capability of the 9000 with a new improved nozzle design to truly make the 9935 the state-of-the-art Arc Spray gun.

Praxair has modeled equipment strategies around reliability and versatility in use, operation and application. The Arc Spray process itself provides the best combination of reliability and versatility of all thermal spray processes, and the 8830 and 8835 have a reputation for great performance and reliable operation in thousands of applications through the years. The guns are designed to perform with minimum operator adjustment, assuring quality coatings time and time again. Process set-up includes only loading wire, setting the voltage, and pushing the "On" button. No other adjustments are needed. The 8835 offers the same properties as the 8830, but also includes the versatility of modular design. It can be unbundled - the console and the wire feed cart can be separated from the power supply to add more range of use. The 8835's PLC controls are designed for hand or robotic operation and provide consistently repeatable coatings through a multitude of application and control options

• Optimum energy transfer tip/tube assembly
• Error-proof alignment housing
• Permanent arc shield protection
• Double yoke wire feed unit
• 350-amp 100% duty cycle power supply

A versatile robust option, the BP-400 features a lightweight point-and-shoot gun utilizing "push" wire feed technology. Designed with a 350-amp output, the system provides both application and production flexibility with superior coating results.

A combination of the best-of-all-worlds in TAFA products, the CoArc system features the 9935 350-amp gun combining the robust 8835-type drive with high air flow capability and a "pull" or "push/pull" wire delivery system. Designed with a variety of "state-of-theart" features and options, it revolutionizes arc spraying by close-looping the spray process.

The flexibility of the BP- 400 is such that it can function in hand-held or fully automated configurations in applications such as spraying varistors.

Designed with reliability, robustness and flexibility in mind, the BP-400 can handle a variety of applications without compromising coating quality. Lightweight, portable and easy to use, the BP-400 offers one-touch, point-and-shoot operation. Based on a highly engineered “push” wire delivery system, the BP-400 virtually eliminates drive mechanism maintenance. This leads to lightweight gun design, fewer worries, and reliable operation.

• "Push" wire feed design
• Lightweight gun with no moving parts
• Synchronous dual wire feeding
• 350-amp 100% duty cycle power supply
• Handheld or machine mounted

Offering all the benefits of the other Arc Spray models plus much more, the 9935 gun when used with the CoArcTM system provide modularity, and robustness. Advanced controls make the CoArc system the ultimate in flexibility and ease-of-use. The CoArc system has the option of supplying the wire with "push/pull" technology and when combined with the optional closed-loop control of gun head's voltage and air pressure, truly revolutionizing the arc spray process to ensure consistent, reproducible coating quality

• Touch-screen operator interface
• Monitoring of spray head voltage and air pressure
• Recipe storage
• Simple, modular design
• Advanced power supply

Simple to operate yet robust, the BP-400 Arc Spray system produces high-quality metallic coatings

The CoArc system is designed for automated spraying yet offers optional hand spraying capability. The 9935 gun incorporates highflow air design that when combined with the optional closed-loop control feature ensures consistent, reproducible coating quality.
