Product Description
The FLEXTEC™ 650 is a multi-process CC/CV DC
inverter and is rated for 650 amps, 44 volts at a 100%
duty cycle.
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™ 650&450 are
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
FLEXTEC™ 650 operates on 3 phase 380V, 460V, or
575V 50hz or 60hz power. The FLEXTEC™ 450 CE
operates on 380V, 400V, or 415V 50hz or 60hz power.
The FLEXTEC™ 650&450 are designed for CC-SMAW,
CC-GTAW (lift tig), CV-GMAW, CV-FCAW-SS, CV-
FCAW-GS and CV-SAW (only for Flextec™ 650)
welding processes. CAG (arc gouging) is also supported
Design Features
Severe Duty Design for outdoor use (IP23 rating)
Passive Power Factor Correction – reliably gives
88% (for Flextec™ 650) and 95% (for Flextec™
450) power factor for lower installation costs.
91% (for Flextec™ 650) and 89% (for Flextec™
450) Efficiency rating – reduces electrical utility
costs.
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
trouble shooting.
Electronic over current protection.
Input voltage misconnection protection.
Utilizes digital signal processing and microprocessor
control.
VRD™ Voltage Reduction Device - Enable this
function for reduced OCV in CC modes for added
safety.
Capabilities
The following capabilities are supported: Wire Feeders:
LF33, LN10, DH10, LN25-Pro, LT-7Tractor and NA
series (only for Flextec™ 650).
