“W” Type Lasers
Water cooled lasers require
½ inch plastic hose water connections before operation.
See “
Other Connection Details
” below. 1625 water cooled lasers detect water flow. If
the laser is operated without water flow or if the laser is not receiving enough water, a
fault will occur (see fault light chart). If the flow is too high, the pressure may exceed the
maximum limit of 60 psi and a fault will occur. Flow rates exceeding 4 gallons/min. are
not recommended or needed. If the water flow becomes too high or too low, there will
be a 10 second delay before the water fault occurs.
Operation of Unit
1. Mount the laser in a manner such that the beam will strike a target capable of
absorbing >300 watts of power. Make sure that the aperture is clear of
obstruction. See pages 14 and 15 for the power supply connections.
Remove
the aperture cover .
2. Confirm that the signal connections to the laser are secure and tight. Make sure
that the power supply unit is correctly connected, including the blue air hose.
Make sure the inner desiccant and outer air filters are in place. (The desiccant
filter must be changed every 300 to 700 hours of operation depending on the
humidity.) Make sure that the water connections are in place and the water flow
direction is correct.
3. Connect the laser power leads to power supply terminals, Red (+) and Black (-)
using at least 6-gauge wire. Be careful not to over-
tighten the 7/16” bolt on the
(+) connection at the laser. This connection is part of an RF feed-through filter
and can be damaged.
4. Make sure the "INTERLOCK" is off or the interlock line is ungrounded.
5. Start the water flow. Make sure that the water is flowing out of the flow turbine
assembly.
6. Power up the DC supply. Check that the fault light is off and the ready light is on.
Wait 20 seconds. If the ready light is still on after 20 seconds, then the air and
water flow is within the proper range.
7. If the Key Switch function is enabled, this line must be toggled from off to on to
arm the laser. If the switch is closed when power is applied, then turn it off and
then on. There will be a 6 second delay before the green "READY" light lights.
This switch must be toggled to arm the system after power up. (NOTE: This
function depends on the software version and programing. OEM lasers are
shipped without this function.)
8. When the system arms to "READY" and the interlock line is closed, the "LASE"
light might also light faintly if the tickle is being applied. The "LASE" light will get
brighter as the power (PWM duty) increases. This is normal.
