Lincoln Electric INVERTEC IM526-B - Manual (Page 7)

PRODUCT DESCRIPTION
The Invertec V300-PRO is a 300 amp arc welding
power source that utilizes single or three phase input
power to produce either constant voltage or constant
current outputs. The V300-PRO is designed for 60 Hz
supply systems. The welding response of the Invertec
has been optimized for GMAW, SMAW, TIG and
FCAW processes. It is designed to be used with the
LN-25 and LN-7 semiautomatic wire feeders.

WARNING
LOCATION
The Invertec has been designed with many features to
protect it from harsh environments. Even so, it is
important that simple preventative measures are fol-
lowed in order to assure long life and reliable opera-
tion.
• The machine must be located where there is free
circulation of clean air such that air movement into
the sides and out the bottom and front will not be
restricted. Dirt and dust that can be drawn into the
machine should be kept to a minimum. Failure to
observe these precautions can result in excessive
operating temperatures and nuisance shutdown of
the Invertec.
• Keep machine dry. Shelter from rain and snow. Do
not place on wet ground or in puddles.
ELECTRICAL INSTALLATION
1. The Invertec should be connected only by a quali-
fied electrician. Installation should be made in
accordance with the U.S. National Electrical Code,
all local codes and the information detailed below.
2. Single voltage, 575 VAC machines, can only be
connected to 575 VAC. No internal reconnection
for other input voltages is possible.
3. Initial 208 VAC and 230 VAC operation will require
a voltage panel setup, as will later reconnection
back to 460 VAC:
a. Open the access panel on the right side of
the machine.
b. For 208 or 230: Position the large switch to
200-230.
For 460: Position the large switch to 380-460.
c. Move the “A” lead to the appropriate terminal.
