GENERAL DESCRIPTION
The INVERTER ARC™ 120 is a 90 amp arc welding power source which utilizes single phase input power to produce constant current output. The welding response of this Inverter has been optimized for stick (SMAW) welding.
WELDING CAPABILITY
The INVERTER ARC™ 120 is rated at 70 amps, 22.8 volts, at 20% duty cycle on a ten minute basis. It is capable of higher duty cycles at lower output currents. If the duty cycle is exceeded, a thermal protector will shut off the output until the machine cools. See Table A.1 in the INSTALLATION Section for other rated out- puts.
The INVERTER ARC™ 120 is recommended for the following Electrode Types and Diameters:
