PRODUCT DESCRIPTION

The FLEXTEC™ 450 CE is a multi-process CC/CV DC inverter and is rated for 450 amps, 38 volts at a 60% duty cycle. The Flextec is intended for both fac- tory and field operation. It comes in a compact, rugged case that is designed for portability and out- door use with an IP23 environmental rating. The user interface of the FLEXTEC™ 450 CE is simple and intuitive. Weld modes are selected by a 4 position selector switch. Volts and Amps are displayed 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 FLEXTEC™ 450 CE operates on 380V, 400V, or 415V 50hz or 60hz power.

DUTY CYCLE

The FLEXTEC™ 450 CE 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 maximum output of the machine is 500 amps.

The FLEXTEC™ 450 CE 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.
