The RS 840 is a 4000-watt gas-transport laser that utilizes state of the art controls to provide reliable and versatile laser power for your processing requirements. It's industrial design allows it to be operated in the toughest production facilities. The RS 840 is used in a variety of materials-processing applications. These include welding, heat-treating, cutting and cladding.
High Quality Beam - Provides a very stable, multi-mode beam ideal for welding, heat treating and cladding
Microprocessor control - allows a variety of control features through a microprocessor
Integral gas recirculation - minimizes the amount of gas required
Permanent Mirror Alignment - Simplifies the replacement of mirrors
Stabalized Resonator - Provides a stable output beam by fixing the position of each mirror
Compact Package - Combines the laser head and power supply to minimize floor-space usage
Ballasted Discharge - Allows for smooth variability in producing the same, high quality mode throughout the RS 840's 400-watt to 4000-watt power range
Low operating cost - The cost of operating the RS 840 is minimal. These features provide quick start-up, promote low facilities usage, and reduce service time.
Enclosed-resonator assembly - In addition to the use of the graphite epoxy composite resonator, all of the RS 840's intracavity mirrors are contained under vacuum in the laser head's casting. The absence of pressure and temperature differences affecting the stability of these key components ensures complete warm-up within minutes from a cold start.
Gas Recirculator - The pumping efficiency of a tangential blower used in the RS 840's gas flow system ensures minimal gas consumption without concerns of contamination, failure, or added expense from a gas re-cycler.
System Diagnostics - While the RS 840's is operating, the microprocessor continually updates the status of over 20 control functions 40 times a second. The microprocessor reports potential trouble and its location. All components are easily accessible, further reducing the time required for service
Permanent Mirror Alignment - The internal mirrors mount against factory adjusting pins. This eliminates the need for skilled labor and alignment equipment to perform field replacement.
User friendly Interface - Adaptability is the key to achieving the RS 840's processing potential. The RS 840 features easy installation, programmable control, simplified interfacing, and hands-off operation.
Programmable control - The RS 840's solid-state electronics automate most functions. These include initiating gas fill, stabalizing pressure, and regulating power and current.
I/O Ports - Since for most application the laser will become part of a turnkey system, 100 volts AC input/output for all major laser functions are provided for remote operation.
