OPERATION
FLEXTEC ® 650x
PRODUCT DESCRIPTION
The FLEXTEC ® 650x is a multi-process CC/CV DC inverter and is
rated for 650 amps, 44 volts at a 100% duty cycle. The
FLEXTEC
® 650x 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
® 650x is simple and intuitive. Weld
modes are selected via a 6 position selector switch. Volts and
Amps are displayed on an easy to view LED display, and the amps
and volts are set via a large output control knob. A hot start and an
arc control knob allow for finer tuning of the welding arc for the
application.
The FLEXTEC ® 650x is designed for the North America and export
markets and operates on 3 phase 380V, 460V, or 575V 50hz or
60hz power.
DUTY CYCLE
The FLEXTEC ® 650x is capable of welding at a 100% duty cycle
(continuous welding) at 650 amps rated output. The 60% duty
cycle rating is 750 amps (based off of a ten minute cycle – 6
minutes on time and 4 minutes off time). The maximum output of
the machine is 815 amps.
The FLEXTEC ® 650x is also rated for Desert Duty, elevated
temperature operation, in a 55°C ambient. The machine is de-
rated for this application. (See Table in the Installation Section.
DESIGN FEATURES
• Severe Duty Design for outdoor use (IP23 rating)
• Passive Power Factor Correction – reliably gives 88% power
factor for lower installation costs.
• 91% Efficiency rating – reduces electrical utility costs.
• Simple user interface - user interface is designed with the
operator in mind. Getting setup for the weld is several clicks
away and even the most novice welder can be confident 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.
• Reversible handles for ease of lifting and transporting
• Multiple options for lifting / transporting: Reversible handles;
eyelet lifting bolts; and single forklift fork access
• Error Codes display on LED screen for ease of trouble
shooting
• Electronic over current protection.
• Input voltage mis-connection protection.
• Utilizes digital signal processing and microprocessor control.
• VRD™ (Voltage Reduction Device)- Enable this function for
reduced OCV in CC modes for added safety.
RECOmmENDED PROCESSES
The FLEXTEC ® 650x is designed for CC-SMAW, CC-GTAW (lift tig),
CV-GMAW, CV-FCAW-S, CV-FCAW-G and CV-SAW welding
processes. CAG (arc gouging) is also supported.
