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.

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 55NC(131NF) ambient.
The machine is output de-rated for this application.

• Severe Duty Design for outdoor use (IP23 rating).
• Passive Power Factor Correction – reliably gives
95% power factor for lower installation costs.
• 89% Efficiency rating – reduces electrical utility
costs.
• Simple user interface - designed with the operator in
mind. Getting setup for the weld is several clicks
away and even the most novice welder can be confi-
dent he is setup properly.
• F.A.N. (fan as needed). Cooling fan runs when the
output is energized and for a 5 minute cool down
period after output is disabled.
• Thermal protection by thermostats with Thermal
Indicator LED.
• Error Codes display on LED screen for ease of trou-
ble shooting.
• Electronic over current protection.
• Input voltage misconnection protection.
• Utilizes digital signal processing and microprocessor
control.
