LW500A/LW600A PULSED Nd:YAG LASER

CHAPTER 1
SYSTEM DESCRIPTION
Section I: Features
For the rest of this manual, the LW500A(E) / ML-2651B(-CE) and LW600A(E) / ML-2650B(-CE) Laser
will be referred to simply as the Laser. The Laser is a compact, pulsed, Nd:YAG laser designed as a
precision spot and seam welder. It incorporates the following features in its design:
The Compact Nd:YAG Laser is equipped with laser power feedback control to operate with the
same performance shot after shot.
The Laser can handle a wide variety of workpieces. Up to 32 different weld schedule settings
can be programmed into the Laser, each with its own unique weld characteristics.
High output repetition (500 pps max.) supports seam welding and high-speed processing.
The Laser controller is detachable from the main body of the Laser which allows remote control.
A variety of input and output signals allow the Laser to be connected to automated equipment.
The power monitor measures both the oscillation output energy (J) and its mean power (W). In
addition, an oscillation output energy comparator (upper-lower limit judgment) is provided for
quality control purposes.
For seam welding, the output can be set to fade-in at the start of a weld and fade-out at the end
of a weld, to smooth overlaps at both ends of the weld.
Use of high-precision optical fiber eliminates the optical axis adjustment usually needed every
time the fiber is removed and reinstalled.
Options
Optical fiber brakage/detatchment detection is available.
Multi-Workstation Interlock function is available.
The External Communications function allows central control of all data, such as parameter
settings and monitored values for the Laser.
