Intuitive Interface LCD Display 

Ensure proper machine setup and parameter selection with informative on-screen explanations and dynamic images.  


Program Memory 

Allows easy naming, saving and recalling of favorite weld settings. 


Pro-Set Feature (professional settings) 

This feature eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of pre-set controls. Simply select the feature and adjust until Pro-Set appears on the display. The Pro-Set feature is available for Balance, Frequency, Pulse and DIG parameters. 


Locks and Limits 

Provides control of the weld parameter ranges minimizing deviations from the welding procedure specifications (WPS). 



QuietPulse is activated by changing the waveshape for DC pulse welding, creating a slower, more fluid transition between the background and peak amperage to create the least possible audible noise. 


USB Port 

Provides the ability to easily update software, back-up settings and transfer saved weld programs from one unit to the next. 


Auto-Line™ Technology 

For portability and reliability this inverter power supply allows for any single-phase input voltage hookup (208–600 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power. 


Stick Features 

Tailored arc control (DIG) allows the arc characteristics to be changed for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010. Hot Start™ adaptive control provides positive arc starts without sticking.
