A-3SELECT 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 mini-
mum. Failure to observe these precautions can result
in excessive operating temperatures and nuisance
shutdowns.
LIFTING
Both handles should be used when lifting the FX450.
When using a crane or overhead device a lifting strap
should be connected to both handles. Do not attempt
to lift the FX450 with accessories attached to it.
STACKING
The FX450 cannot be stacked.
ENVIRONMENTAL LIMITATIONS
The FX450 is IP23 rated for use in an outdoor envi-
ronment. The FX450 should not be subjected to falling
water during use nor should any parts of it be sub-
merged in water. Doing so may cause improper oper-
ation as well as pose a safety hazard. The best prac-
tice is to keep the machine in a dry, sheltered area.
