Lincoln Electric IM789 WELDMARK 135 PLUS - Manual (Page 13)

A-6 A-6 INSTALLATION
CODE REQUIREMENTS FOR INPUT
CONNECTIONS
This welding machine must be connected to
power source in accordance with applicable elec-
trical codes.
The United States National Electrical Code (Article
630-B, 1990 Edition) provides standards for amperage
handling capability of supply conductors based on
duty cycle of the welding source.
If there is any question about the installation meeting
applicable electrical code requirements, consult a
qualified electrician.
Requirements For Rated Output
A power cord with a 15 amp, 125 volt, three prong
plug (NEMA Type 5-15P) is factory installed on the
welder. Connect this plug to a mating grounded recep-
tacle which is connected to a 20 amp branch circuit
with a nominal voltage rating of 115 to 125 volts, 60
Hertz, AC only.
The rated output with this installation is 90 amps, 18
Volts, 20% duty cycle (2 minutes of every 10 minutes
used for welding).
Do not connect the welder to an input power sup-
ply with a rated voltage that is greater than 125
volts.
Do not remove the power cord ground prong.
Requirements For Maximum Output
In order to utilize the maximum output capability of the
machine, a branch circuit capable of 25 amps at 115
to 125 volts, 60 Hertz is required. This generally
applies when welding steel that is equal to or greater
than 12 gauge, 0.105
” (2.5 mm) in thickness.
