SAFETY PRECAUTIONS
ELECTRIC SHOCK CAN KILL.
•
Only qualified personnel should install
this machine.
•
Turn the input power OFF at the dis-
connect switch or fuse box before
working on the equipment.
•
Do not touch electrically hot parts.
•
Always connect the IDEALARC SP-250 grounding
terminal (located on the side of the Case Back
Assembly) to a good electrical earth ground.
•
Set the IDEALARC SP-250 Power switch to the
OFF position when connecting power cord to input
power.
____________________________________
SELECT PROPER LOCATION
Place the IDEALARC SP-250 where clean air can
freely circulate in through the front intake and out
through the rear louvers. Dirt, dust, or any foreign
material that can be drawn into the machine should be
kept at a minimum. Not following these precautions
can result in the nuisance shutdown of the machine
because of excessive operating temperatures.
STACKING
The IDEALARC SP-250 cannot be stacked.
INPUT CONNECTIONS
All input power must be electrically
disconnected before proceeding.

INSTALLATION
IDEALARC SP-250
A-2
1.
Before starting the installation, check with the local
power company to determine if there is any ques-
tion about whether your power supply is adequate
for the voltage, 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 three-phase line.
2.
Models that have multiple input voltages specified
on the nameplate (e.g., 208/230) are shipped con-
nected for the highest voltage. If the welder is to
be operated at a lower voltage, it must be recon-
nected according to the instructions on the inside
of the removable panel (Reconnect Access Door)
near the top left side of the Case Back Assembly.
Also see the Reconnect Section of this manual for
details on reconnecting the machine to operate at
different voltages.
3.
Be sure the voltage, phase, and frequency of the
input power is as specified on the machine rating
plate. See Figure A.1 for the location of the
machine’s input cord entry, Reconnect Access
Door, Reconnect Panel, and Rear Nameplate.
