Everlast PowerPro 256 Operator's Manual page 12

SECTION 1
1.1 This manual has been compiled to give
an overview of operation and is designed to
offer information centered around safe,
practical use of the machine. It is not in-
tended to teach welding technique. All
suggestions and techniques given are ap-
proximations and should be used as a gen-
eral guide only.
1.2 To ensure that your Everlast product is
in top condition, carefully inspect unit for
damage upon opening the box, looking for
damage on the surface of the unit and to
the machine itself and all its accessories.
Do this immediately upon receipt of prod-
uct. Any damage issues must be resolved
right away. It is further recommended that
the product be tested at the same time for
proper operation, even if it is to be stored
for a while. Check to make sure all passag-
es, connections and fittings are clear of
any packing material or other obstruction.
Record the serial number on the page pro-
vided in this manual. Include purchase date
for warranty reference. Serial numbers are
located on either the rear or side of the ma-
chine.
1.3 The Power® Series multi-process units
are used in industrial settings performing
day to day fabrication and repair activities.
The exceptional arc characteristics are
provided by the inverter based technology
that employs the use of reliable IGBT tran-
sistor technology from Germany. Light-
weight inverters allow a machine to be fine-
ly tuned for precise arc characteristics,
while consuming less power than the larg-
er transformer based machines. Although
it varies upon the model, precise control of
the welding arc cycle is managed through
the adjustments available on the panel
face. The independent controls allow for a
virtually limitless number of configurations
to suit every type metal and weld condition
encountered. The use of High Frequency
arc starting in the TIG mode, greatly simpli-
fies the TIG(GTAW) process. The incorpo-
ration of the advanced Pilot Arc in the Plas-
ma Mode eliminates the need for touch
starts and greatly improves consumable
life.
INTRODUCTION AND SPECIFICATIONS
1.4 Be careful to observe duty
cycles of the machine posted in
this manual and on the machine
itself. A duty cycle is a rating of
percentage of time out of 10 minutes the
machine can be used at the rated power
setting . Overheating may occur if the duty
cycle is exceeded. On multi-voltage, multi-
phased machines, note that the rated duty
cycle will change. For example, the duty
cycle of the PowerPro 256 is 35% at 250
amps which continuous operation is al-
lowed for 6 out of 10 minutes before a cool-
ing period of 4 minutes is needed. SMAW
operation on all units is restricted to 35% at
maximum amperage.
1.5 The unit should be stored in a dry
place for long term storage. Humid/wet
conditions can contribute to the eventual
decay of the circuitry in the machine. For
safety reasons, do not use this machine
directly in the rain or with soaked clothing
or protective gear.
1.6 Use only the provided handles to lift the
unit. Do not suspend by cables or chains
or use fork trucks to lift the units. If neces-
sary, use two people to carry the unit.
1.7 Make sure that the units cooling fan
and exhaust vents are kept free of obstruc-
tion. Before every operation, inspect the
unit for unexpected obstructions such as
insect and rat nests. From time to time, a
cleaning of the machine with low pressure
air and a small plastic bristle brush is nec-
essary to ensure long life. On these occa-
sions only, unplug unit and remove cover
to access interior. Concentrate efforts on
aluminum heat sinks and panel vents to
remove dust and dirt.
1.8 Refer to the following pages to locate
your particular unit and its specifications.
Note that product specifications are sub-
ject to change without notice due to prod-
uct improvements. If any additional infor-
mation is needed contact Everlast. Simple
wiring diagrams may be obtained for basic
diagnosis and may be obtained from tech-
nical support.
