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 mini-
mum. Failure to observe these precautions can result
in excessive operating temperatures and nuisance
shutdowns.

Both handles should be used when lifting the
Flextec™ 450. When using a crane or overhead
device a lifting strap should be connected to both han-
dles. Do not attempt to lift the Flextec™ 450 with
accessories attached to it.

The Flextec™ 450 cannot be stacked.

The Flextec™ 450 is IP23 rated for use in an outdoor
environment. The Flextec™ 450 should not be sub-
jected 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,
sheltered area.

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 meth-
ods.

Locate the Flextec™ 450 away from radio controlled
machinery. The normal operation of the Flextec™ 450
may adversely affect the operation of RF controlled
equipment, which may result in bodily injury or dam-
age to the equipment.
