Description

Big Blue 450 Duo CST

Durable dual-operator welder/generator. 
The Big Blue 450 Duo CST delivers proven CST stick/TIG performance with two superior arcs in one compact package, for maximum productivity and efficiency.

Mitsubishi S4L2 four-cylinder diesel Used in industrial applications around the world, the S4L2 is designed to run 10,000 hours before major overhaul

Superior stick arc performance  even on the difficult-to-run electrodes like E6010. 

Adaptive Hot Start™ for stick  arc starts automatically increases  the output amperage at the start of  a weld should the start require it. Prevents the electrode from sticking and creating an inclusion.  

Lift-Arc™ start for TIG starts without the use of high frequency. 

Remote amperage control provided through 14-pin receptacle on front  of the machine permits the use of standard and wireless amperage control devices. 

Vandalism lockout kit (not shown) Lockable hinged steel panel protects front control panel and ignition switch.

Meter maintenance displays.

• Hour meter function
• Oil change interval
• High coolant temperature and low oil pressure shutdowns
• Low fuel shutdown — engine shuts down before system runs out of fuel, making restarts easy

Quiet operation At just 71 decibels at 23 feet (7 m), it’s quieter than most single-operator models, improving jobsite communication and safety. 

Thermal overload protection prevents machine damage if the duty cycle is exceeded or airflow  is blocked. 

High efficiency Three-phase,  rotating-field generator requires less fuel and horsepower to operate.
