SELECT SUITABLE LOCATION
The POWER WAVE ® C300 will operate in harsh environ-
ments. Even so, it is important that simple preventative
measures are followed in order to assure long life and reli-
able operation.
• The machine must be located where there is free circula-
tion of clean air such that air movement in the back, out
the sides and bottom will not be restricted.
• Dirt and dust that can be drawn into the machine should
be kept to a minimum. The use of air filters on the air
intake is not recommended because normal air flow may
be restricted. Failure to observe these precautions can
result in excessive operating temperatures and nuisance
shutdown.
• Keep machine dry. Shelter from rain and snow. Do not
place on wet ground or in puddles.
• Do not mount the POWER WAVE ® C300 over com-
bustible 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.
WARNING
LIFTING
Both handles should be used when lifting POWER WAVE ®
C300. When using a crane or overhead device a lifting strap
should be connected to both handles. Do not attempt to lift the
POWER WAVE
® C300 with accessories attached to it.
Do not weld with the POWER WAVE ® C300 while the machine
is suspended by the handles.
STACKING
The POWER WAVE ® C300 cannot be stacked.
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.
INPUT AND GROUND CONNECTIONS
Only a qualified electrician should connect the POWER WAVE ®
C300. Installation should be made in accordance with the
appropriate National Electrical Code, all local codes and the
information in this manual.
MACHINE GROUNDING
The frame of the welder must be grounded. A ground terminal
marked with a ground symbol is located next to the input
power connection block (in the access panel under the wire
spool).
See your local and national electrical codes for proper ground-
ing methods.
HIGH FREQUENCY PROTECTION
The EMC classification of the POWER WAVE ® C300 is
Industrial, Scientific and Medical (ISM) group 2, class A. The
POWER WAVE
® C300 is for industrial use only. (See
Electromagnetic Compatibility EMC Safety Section).
Locate the POWER WAVE ® C300 away from radio controlled machin-
ery. The normal operation of the POWER WAVE ® C300 may adversely
affect the operation of RF controlled equipment, which may result in
bodily injury or damage to the equipment.
• Lift only with equipment of adequate lifting
capacity.
• Be sure machine is stable when lifting.
• Do not operate machine while suspended
when lifting.
