FLEXTEC™ 500 P

INPUT VOLTAGE SELECTION

Welders are shipped connected for 460V input voltage. If the
Auxiliary lead (indicated as 'A') is placed in the wrong position and
power is applied to the machine, the machine will protect itself and
display an error message:
• "Err" "713" or "714" will be shown on the display.
• The User Interface board and Switch Boards will blink out error 713
or 714 on their status LEDs.
• The weld output will be turned off and the control board will force
itself into an idle state. The FAN will run continuously.
• The machine will need to have the misconnect condition removed
before it will recover.
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 and front.
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™ 500 P has two handles that can be used to lift the
machine.
Both handles should be used when lifting the machine. 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™ 500 P with accessories attached to it.
Stacking
The Flextec™ 500 P cannot be stacked.

Environmental limitations

The Flextec™ 500 P is IP23 rated for use in an outdoor environment.
The machine 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, sheltered area.
Do not mount the Flextec™ 500 P 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.

HIGH FREQUENCY PROTECTION

Locate the Flextec™ 500 P away from radio controlled machinery.
The normal operation of the machine may adversely affect the
operation of RF controlled equipment, which may result in bodily
injury or damage to the equipment.
