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 WIRE-MATIC 255 ground-
ing terminal to a good electrical earth ground
through the cable plug per the National
Electrical Code.
•
Set the Wire-Matic 255 ON/OFF Power switch to
the OFF position when connecting power cord
to input power.
____________________________________
SELECT PROPER LOCATION
Place the WIRE-MATIC 255 where clean, cooling air
can freely circulate in through the case back louvers
and out through the case front louvers. Dirt, dust, or
any foreign material that can be drawn into the
machine case back louvers should be kept at a mini-
mum. Not following these precautions can result in the
nuisance shutdown of the machine because of exces-
sive operating temperatures.
STACKING
The WIRE-MATIC 255 cannot be stacked.
TILTING
The Wire-Matic 255 must be placed on a stable, level
surface so it will not topple over. Do not place the
machine on an incline.

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. 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 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.
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, and Reconnect Panel, and Rear Nameplate.
