120V INPUT

The INVERTER ARC™ 120 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 INVERTER ARC™ 120 is
available when connected to a 20A branch circuit.
When connected to a branch circuit with lower ampac-
ity, lower welding current and duty cycle must be
used. An output guide is provided below. The values
are approximate and must be adjusted downward if
the fuse or circuit breaker trips off. Other loads on the
circuit and fuse/circuit breaker characteristics will
affect the available output. Do not exceed these weld-
ing conditions: (See Table A.1)
