PRODuCT DESCRIPTION

The FX450 is a multi-process CC/CV DC inverter and is rated for 450 amps, 38 volts at a 60% duty cycle. This machine is intended for both factory and field operation. It comes in a compact, rugged case that is designed for portability and outdoor use with an IP23 environmental rating. The user interface of the FX450 is simple and intuitive. Weld modes are selected by a 4 position selector switch. Volts and Amps are dis- played on an easy to view LED display, and the amps and volts are set by a large output control knob. A hot start toggle selector switch and an arc control knob allow for finer tuning of the welding arc. The FX450 operates on 380V, 460V, or 575V 50hz or 60hz power.

DuTY CYCLE

The FX450 is capable of welding at a 100% duty cycle (continuous welding) at 400 amps rated output. The 60% rating is 450 amps base off of a 10 minute cycle - 6 minutes on time and 4 minutes off time. The maxi- mum output of the machine is 500 amps.

The FX450 is also rated for Desert Duty, elevated temperature operation, in a 55°C(131°F) ambient. The machine is output de-rated for this application.
