INSTALLATION
SPARKS can
POWER MIG
ONLY QUALIFIED PERSONNEL SHOULD
INSTALL, USE OR SERVICE THIS EQUIP-
MENT.
UNCRATING THE POWER MIG
350MP
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.
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. The POWER MIG 350MP is supplied connected
®
for 230 Volt Input. If the welder is to be operated on
another voltage, it must be reconnected according
