SAFETY PRECAUTIONS

WARNING
ELECTRIC SHOCK can kill.
• Only qualified personnel should perform
this installation.
• Only personnel that have read and under-
stood the SP-255 Operating Manual should
install and operate this equipment.
• Machine must be plugged into a receptacle
which is grounded per any national, local
or other applicable electrical codes.
• Turn the power switch on the SP-255 "off"
before connecting or disconnecting gun
and cable, output cables or other equip-
ment.

UNCRATING THE SP-255

Remove the staples from the bottom edge of the car-
ton and lift off. Cut the tape securing the two rear
wheels to the wooden shipping pallet. Using a 1/2 inch
(or 13 mm) wrench or socket, remove the two screws
which attach the pallet to the bottom of the SP-255.

LOCATION

Locate the welder in a dry location where there is free
circulation of clean air into the louvers in the back and
out the front. A location that minimizes the amount of
smoke and dirt drawn into the rear louvers reduces
the chance of dirt accumulation that can block air pas-
sages and cause overheating.

•
cally disconnected before

INSTALLATION
1. Before starting the installation, check with the local
power company if there is any question about
whether your power supply is adequate for the volt-
age, amperes, phase, and frequency specified on
the welder nameplate. Also, be sure the planned
installation will meet the U.S. National Electrical
Code and local code requirements. This welder
may be operated from a single phase line or from
one phase of a two or three phase line.
2. Models that have multiple input voltages specified
on the nameplate (e.g., 208/230) are shipped con-
nected for the higher voltage. If the welder is to be
operated on lower voltage, it must be reconnected
according to the instructions on the inside of the
removable panel near the top left side of the rear
panel. These instructions are repeated below:
Make certain that the input power is electrically
disconnected before removing the screw that
holds the removable rear panel in place.
3. The 208/230 volt 60 Hz model SP-255 is shipped
with a 10 ft. (3.0 m) input cable and plug connected
to the welder. A matching receptacle is supplied
with the machine. Mount the receptacle in a suit-
able location using the screws provided. Be sure it
can be reached by the plug on the input cable
attached to the welder. Mount with the grounding
terminal at the top to allow the power cable to hang
down without bending.
