WELD-PAK 90i
INPUT POWER CONNECTION
The machine has one input connection, the power input cable. The
power input cable is located on the rear.
The Weld-Pak 90i is provided with a 120V cable, 6.0ft. (1.8m)
in length, with a 15Amp 5-15P plug molded onto the cord.
The rated output of the Weld-Pak 90i
connected to a 20A branch circuit. When connected to a branch
circuit with lower capacity, lower welding current and duty cycle
must be used.
CODE REQUIREMENTS FOR ELECTRICAL INPUT
CONNECTIONS
WARNING
This welding machine must be connected to a power source
in accordance with applicable electrical codes.
The National Electrical Code 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.
WARNING
Do not connect the machine to an input power supply with a
rated voltage that is greater than 125 volts.
Do not remove the power cord ground prong.
EXTENSION CORD USAGE
If an extension cord is required, use one that is rated for the
application and is 3 conductor #14 AWG (2.1 mm2) or larger. The
recommended maximum lengths are 25 ft (7.5 m) if #14 AWG (2.1
mm2) is used and 50 ft (15 m) if #12 AWG (3.3 mm2) is used.
FLUX-CORED (INNERSHIELD) WELDING
The recommended electrode for the flux-cored, self-shielded
process is 0.035" (0.9 mm) diameter Lincoln Innershield
