Safety Precautions
WARNING
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground.
• Always wear dry insulating gloves.
------------------------------------------------------------------------
FUMES AND GASES can be dangerous.
• Keep your head out of fumes.
• Use ventilation or exhaust to remove
fumes from breathing zone.
------------------------------------------------------------------------
WELDING SPARKS can cause fire or
explosion.
• Keep flammable material away.
• Do not weld on closed containers.
------------------------------------------------------------------------
ARC RAYS can burn eyes and skin.
• Wear eye, ear and body
protection.
------------------------------------------------------------
See additional warning information at the
front of this operator's manual.
-----------------------------------------------------------
• Connect the E300 grounding terminal located under
the reconnect panel (marked
cal ground per the U.S. National Electrical Code and
any applicable local codes.
• Turn the power switch on the E300 "OFF" before
connecting or disconnecting output cables or other
equipment.
• Only qualified personnel should perform this installa-
tion.

Location
The machine should be located in a clean, dry place
where there is free circulation of clean air such that air
movement in the back and along the sides will not be
restricted. Dirt and dust that can be drawn into the
machine should be kept to a minimum. Failure to
observe the precautions can result in excessive
operating temperatures and nuisance shutdown of the
machine.
Input Connections
Be sure the voltage, phase and frequency of the input
power is as specified on the welder rating plate locat-
ed on the rear panel of the machine. Either a single
phase or one phase of a three phase line can be
used.
Have a qualified electrician install the machine per the
following instructions:
Remove the input access panel on the rear panel.
Route the input power lines through the hole in the
rear panel. Lug the input leads with a ring terminal for
a 1/4" (6mm) screw. Connect lugged leads to L1 and
L2 of the reconnect panel per the diagram pasted to
the inside of the input access panel. Input connection
must conform to the U.S. National Electrical Code and
all local codes.
Models designed for two or three input voltages are
shipped connected for the highest voltage.
Reconnect instructions are on the diagram pasted to
the inside of the input access panel. Consult rating
plate on the rear panel for machine input voltage rat-
ing.
The welder frame must be grounded. A stud marked
with the symbol
panel is provided for this purpose. See the U.S.
National Electrical Code for details on proper ground-
ing methods.
Fuse the input circuit with the recommended super lag
fuses. Choose an input and grounding wire size accord-
ing to local codes or use the following table. "Delay type"
circuit breakers may be used in place of fuses. Using
fuses or circuit breakers smaller than recommended may
result in "nuisance" tripping from welder inrush currents
even if not welding at high currents.
