INSTALLATION
INPUT POWER, GROUNDING AND
CONNECTION DIAGRAMS
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 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.
Make certain that the input power is electrically
disconnected before removing the screw on the
reconnect panel access cover.
Read entire installation section before starting
installation.
SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Only qualified personnel should perform
this installation.
• Only personnel that have read and under-
stood the POWER MIG 200 Operating
Manual should install and operate this
equipment.
• Machine must be grounded per any nation-
al, local or other applicable electrical
codes.
• The POWER MIG power switch is to be in
the OFF position when installing work
cable and gun and when connecting other
equipment.
WARNING
UNCRATING THE POWER MIG 200
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 pas-
sages and cause overheating.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts such as
output terminals or internal wiring.
• All input power must be electrically dis-
connected before proceeding.
