Laser Mech FiberMINI 2.0 - Cable Bundling; Fiber Adapter

PLMNL0243 REV. A, Effective Date: 03/24/16 3 FiberMINI ™ 2.0 Operation Manual
 Assist Gas
See Figure 5 for location and hose size.
 Maximum pressure is 20 BAR.
Figure 5
Impurities in the assist gas such as
hydrocarbons (THC) and moisture (H
2
O)
can damage optics, cause power
fluctuations and result in inconsistent cuts.
See the table below for recommended
assist gas specifications.
Impurities can also be picked up in the
supply lines. Non-metallic materials can
allow oxygen and moisture to permeate
the system and can be a source of dust
and hydrocarbons. Stainless steel lines
and fittings are recommended. Filters that
remove particles down to .01 microns and
purifiers that guard against oil or water
getting into the optical system should be
used.
Regulators with a stainless steel
diaphragm are recommended. Industrial
regulators can aspirate air and the
neoprene diaphragm can be a source of
hydrocarbons.
 Purge Gas and Air Cooling
See Figure 5 for location and hose size.
 Purge gas pressure is 0.2 – 0.3 Bar
(3.0 – 5.0 psi).
 Air cooling pressure is 2.1 – 3.4 Bar
(30.0 – 50.0 psi).
2.3 Cable Bundling
The cables need to be bundled in a
manner which allows complete tool
movement without pinching or pulling of
the cables. The FiberMINI
®
2.0 head was
designed so that all cables input in the
same direction – allowing a sleek, easy-to-
manage bundle.
Cabling should not be tethered to the fiber
input connector or the fiber optic cable.
The manner in which the
cables are bundled is one of
the keys to having a successful
cutting cell. The end user is
responsible for documenting
and training personnel on the
best bundling methods for their
application.
2.4 Fiber Adapter
The purpose of the fiber adapter is to
connect the fiber optic cable to the head.
The fiber input is the interface between
the laser and the cutting head. FiberMINI
®
2.0 will adapt to most industrial fibers.
The key features are:
 Several industrial standard styles of
fibers ends are compatible.
o Each of these fibers has a unique
method of securing it to the fiber
input adapter. Refer to the fiber
manufacturer’s information for
specific instructions.
