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)

OUTPUT CONNECTIONS

A quick disconnect system using Twist-Mate™ cable plugs is used for the welding cable connections.

WARNING

ELECTRIC SHOCK can kill.

• Keep the electrode holder and cable insulation in good condition.

•Do not touch electrically live parts or electrode with skin or wet clothing.

•Insulate yourself from work and ground.

•Turn the input line Switch on the INVERTER ARC™ 120 “off” before connecting or discon- necting output cables or other equipment.
