ML-2350AF/2351AF
Thank you for purchasing our YAG Laser Welder ML-2350AF/2351AF.
ML-2350AF-CDRH and ML-2351AF-CDRH are the air-cooled versions of the standard
ML-2350A-CDRH and ML-2351A-CDRH, respectively. This operation manual describes
only the difference of the air-cooled versions from the standard ones.
See the operation manual of the standard version for how to use, such as operation
method.

1. Difference from the Standard Specifications
The laser power supply, oscillator head and cooler are accommodated in one body.
Transportation and installation are easy because the piping for city water is not
necessary.
The air-cooled system does not waste water resources.
How to operate is just the same as the standard ML-2350A-CDRH and
ML-2351A-CDRH.

Power Supply
Power supply 3-phase, 220V AC+10%-15%, 60Hz
3-phase, 380V AC±10%, 50/60Hz (Tap switching)
Max. input current 11A (at 220V AC) / 6.5A (at 380V AC)
Max. apparent power 3.8kVA (at 220V AC) / 4.5kVA (at 380V AC)
Power consumption Maximum: 3.5kW / Stand-by: 0.45kW (at 220V AC)
Maximum: 3.5kW / Stand-by: 0.49kW (at 380V AC)
Breaker rated current (to
be supplied by customers)
For the power supply side, we earnestly recommend
using a leakage breaker with the rated current of 20 A
or more (at 220V) or 10 A or more (at 380V), which is
applicable to harmonics and surges.
Ground Class D (ground resistance: 100 Ωmax.) (at 220V)
Class C (ground resistance: 10 Ωmax.) (at 380V)
Cooler
Heat exchange method Forced air-cooled
Operating room
temperature
5°–30°C (40°C max. cooling water temp.)
The temperature may varies depending on LAMP
INPUT POWER (%) of 80% or higher and installation
conditions. Refer to the Cooling Capability Chart below.
(Provide the provision to measure the difference
between room and coolant temperatures.)
NOTE: Heat of 2.5 kW (2150 kcal/h) is discharged for the maximum rating.
The ML-2350AF/2351AF eliminates city water to improve the factory environment.

Up to 32 schedules can be set by combining
・Laser output waveform
・Laser energy for upper/lower limit judgment
・Number of outputs per second
・Number of repeated outputs

Dimensions 990 (H) x 521.1 (W) x 995 (D) mm
*1) Under the condition that laser output energy is at least 5 J per pulse and peak power is at
least 1
kW.
②Cooling Capability
The chart at left depicts the
cooling capability at 100%
duty cycle. Do not use in
room temperature exceed-
ing the line shown.
See the examples below
for less than 100% duty
cycle:
[Example 1]
Letting LAMP INPUT POWER be 60%, and “1-s laser output—2-s pause” be repeated.
60 x 1/3 = 20
LAMP INPUT POWER of 20% gives the room temperature of about 36C.
Keep room temperature 36C or less.
[Example 2]
Letting LAMP INPUT POWER be 80%, and “3-s laser output—2-s pause” be repeated.
80 x 3/5 = 48
LAMP INPUT POWER of 48% gives the room temperature of about 33.5C.
Keep room temperature 33.5C or less.
