WELDED MATERIALS CAN BURN: Welding generates a large amount of heat. Hot surfaces and
materials in work area can cause serious burns. Use gloves and pliers when touching or moving
materials in the work area.
CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the correct
shielding gas for the process used and properly operating regulators designed for the gas and pressure
used. Always keep cylinders in an upright position securely chained to a fixed support. Do not move or
transport gas cylinders with the protection cap removed. Do not allow the electrode, electrode holder,
work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders must be located
away from areas where they may be subjected to physical damage or the welding process including
sparks and heat sources.
SAFETY MARK: This equipment is suitable for supplying power for welding operations carried out in an
environment with increased hazard of electric shock.
The manufacturer reserves the right to make changes and/or improvements in design without upgrade at the same time
the operator’s manual.
Installation and Operator Instructions
Read this entire section before installation or operation
of the machine.
Location and Environment
THE POWER WAVE
®
S350/S500 CE will operate in
harsh environments. Even so, it is important that simple
preventative measures are followed in order to assure
long life and reliable operation.
The machine must be located where there is free
circulation of clean air such that air movement in the
back, out the sides and bottom will not be restricted.
Do not cover the machine with paper, cloth or rags
when switched on.
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.
This machine has a protection rating of IP23. Keep
machine dry. Shelter from rain and snow. Do not
place on wet ground or in puddles.
Do not use this machine for pipe thawing.
Do not mount the POWER WAVE
®
S350/S500 CE
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 1.6mm thick, which shall
extend not less than 150mm beyond the equipment
on all sides.
Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on electromagnetic compatibility in
this manual.
Do not operate in areas with an ambient temperature
greater than 40°C.
Lifting
WARNING
FALLING EQUIPMENT can cause injury.
Lift only with equipment of adequate lifting capacity.
Be sure machine is stable when lifting.
Do not operate machine while suspended when
lifting.
Both handles should be used when lifting POWER
WAVE
®
S350/S500 CE. When using a crane or
overhead device a lifting strap should be connected to
both handles. Do not attempt to lift the POWER WAVE
®
S350/S500 CE with accessories attached to it.
Stacking
The POWER WAVE
®
S350/S500 CE 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.
Duty Cycle and Overheating
The POWER WAVE
®
S350/S500 CE is rated:
S350: 300A/29 V @ 100% duty cycle, 350A/31,5V @
40% duty cycle
S500: 450A/36,5 V @ 100% duty cycle, 500A/39V @
60% duty cycle
The duty cycle of a welding machine is the percentage of
time in a 10 minute cycle at which the welder can
operate the machine at rated welding current.
Example: 60% duty cycle
Welding for 6 minutes.
Break for 4 minutes.
