SAFETY PRECAUTIONS

WARNING
ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this installation.
• Only personnel that have read
and understood the Power MIG®
255XT Operating Manual should
install
equipment.
• Machine must be grounded per any national,
local or other applicable electrical
codes.
• The Power MIG® 255XT power switch is to be in
the OFF position when installing work cable

--------------------------------------------------------------------------------
UNCRATING THE Power MIG® 255XT
Cut banding and lift off cardboard carton. Cut banding
holding the machine to the skid. Remove foam and
corrugated packing material. Untape accessories from
Gas Bottle Platform. Unscrew the two wood screws
(at the Gas Bottle Platform) holding the machine to
the skid. Roll the machine off the skid assembly.

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
passages and cause overheating.

INSTALLATION
and operate this
Power MIG® 255XT
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 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 on lower voltage, it must be reconnected
according to the instructions in Figure A.1 for dual
voltage machines and Figure A.2 for triple voltage
machines.
WARNING
Make certain that the input power is electrically
disconnected before removing the screw on the
reconnect panel access cover.

3.The 208/230 volt 60 Hz model Power MIG® 255XT
is shipped with a 10 ft. input cable and plug
connect-ed to the welder. Obtain a receptacle and
mount it in a suitable location. 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.
The 230/460/575 volt 60 Hz model is not equipped
with a plug, an input cable or a receptacle.
