FLEXTEC 650x
INSTALLATION
WARNING
ELECTRIC SHOCK can kill.
•
Only qualified personnel should
perform this installation.
•
Turn off input power to the power
source at the disconnect switch or
fuse box before working on this equipment. Turn off
the input power to any other equipment connected to
the welding system at the disconnect switch or fuse
box before working on the equipment.
•
To not touch electrically hot parts.
•
Always connect the flextec™ 650 grounding lug
(located inside the reconnect input access door) to a
proper safety (earth) ground.
VRD™ (VOLTAGE REDUCTION DEVICE)
The VRD™ feature provides additional safety in the CC-Stick
mode. The VRD™ reduces the OCV (Open Circuit Voltage) at the
welding output terminals while not welding to less than 35VDC
peak.
The VRD™ requires that the welding cable connections be kept in
good electrical condition because poor connections will contribute
to poor starting. Having good electrical connections also limits the
possibility of other safety issues such as heat-generated damage,
burns and fires.
The machine is shipped with VRD™ "Disabled". The VRD™
function can be disabled or enabled via dip switches on the
control P.C. board. Dip switch setting will differ depending on
input voltage.
The control board and dip switches can be accessed by removing
the case top and side as shown in the Operation Section figure
B.3.
SELECT SUITAbLE LOCATION
Location and ventilation for cooling
Place the welder where clean cooling air can freely circulate in
through the rear louvers and out through the case sides. Dirt,
dust, or any foreign material that can be drawn into the welder
should be kept at a minimum. Failure to observe these
precautions can result in excessive operating temperatures and
nuisance shutdowns.
LIFTING
The FLEXTEC 650x has 2 lifting eyelets and 2 handles that can be
used to lift the machine. Both handles or both eyelets should be
used when lifting the FLEXTEC 650x.
When using a crane or overhead device to lift using the handles, a
lifting strap should be connected to both handles. Do not attempt
to lift the FLEXTEC 650x with accessories attached to it.
TILTING
Place the machine directly on a secure, level surface or on a
recommended undercarriage. the machine may topple over if this
procedure is not followed.
STACkING
Multiple FLEXTEC 650x's cannot be stacked.
ENVIRONmENTAL LImITATIONS
The FLEXTEC 650x is IP23 rated for use in an outdoor
environment. The FLEXTEC 650x should not be subjected to
falling water during use nor should any parts of it be submerged in
water. Doing so may cause improper operation as well as pose a
safety hazard. The best practice is to keep the machine in a dry,
CAUTION
sheltered area.
Do not mount the FLEXTEC 650x over combustible
surfaces. Where there is a combustible surface
directly under stationary or fixed electrical
equipment, that surface shall be covered with a
steel plate at least .060" (1.6mm) thick, which shall
extend not less than 5.90" (150mm) beyond the equipment
on all sides.
INPUT AND GROUNDING CONNECTIONS
Machine Grounding
The frame of the welder must be grounded. A ground terminal
marked with the symbol shown is located inside the
reconnect/input connection area for this purpose. See your local
and national electrical codes for proper grounding methods.
HIGH FREQUENCY PROTECTION
Locate the FLEXTEC 650x away from radio controlled machinery.
The normal operation of the FLEXTEC 650x may adversely affect
the operation of RF controlled equipment, which may result in
bodily injury or damage to the equipment.
