WARNING

ELECTRIC SHOCK can kill.

•Only qualified personnel should perform this installation.

•Only personnel that have read and under- stood the POWER MIG® 215 Operating Manual should install and operate this equipment.

•Machine must be grounded per any national, local or other applicable electri- cal codes.

•The POWER MIG® power switch is to be in the OFF position when installing work cable and gun and when connecting other equipment.

UNCRATING THE POWER MIG® 215

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.

WARNING

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.

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.

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.

WARNING

Make certain that the input power is electrically disconnected before removing the screw on the reconnect panel access cover.
