To help customers replace older CO2 and YAG production lasers with energy-efficient fiber ones, IPG Photonics Corp. is offering retrofit services. By replacing their older lasers for applications such as cutting, welding and cladding, manufacturers can use their existing motion systems or transfer lines while they obtain newer laser technology. The company has a calculator on its Web site that determines potential electrical energy savings realized from using a fiber laser. Customers who switch will benefit from lower maintenance, no diodes to replace and decreased downtime. Engineers familiar with systems integration, including beam delivery, application development, controllers, robots, software and safety, will provide the service.
