The Flextec™ 450 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 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 Flextec™ 450 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 out-
put control knob. A hot start toggle selector switch
and an arc control knob allow for finer tuning of the
welding arc. The Flextec™ 450 operates on 380V,
460V, or 575V 50hz or 60hz power.

The Flextec™ 450 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 is also rated for Desert Duty, ele-
vated temperature operation, in a 55NC(131NF) ambi-
ent. The machine is output de-rated for this applica-
tion.

• 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

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.
