Auto-Line™ provides state-of-the-art flexibility by automatically connecting to 120-460 VAC, single- or three- phase power without removing the covers to relink the power source. Low OCV Stick reduces open-circuit voltage to 9-14 VDC when power source is not in use. This built-in circuit design eliminates the need for add-on voltage reducers.

Superior Stick arc performance on all input voltages. Even on the difficult to run electrodes like E6010. Portable in shop or at job site - at 32lb the Maxstar 200 STR is easily moved from location to location. Adaptive Hot Start™ for Stick arc starts automatically increases output amperage at start of weld should the start require it. Prevents electrode from sticking and creating an inclusion.

Lift Arc™ start for TIG arc starts without the use of high frequency. Fan-On-Demand™ operates only when needed reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine. Wind Tunnel Technology™ Internal air flow that protects electrical components and PC boards from dirt, dust, debris... greatly improving reliability.

LVC™ Line Voltage Compensation Keeps output of the power source constant regardless of fluctuation in input power ± 10%
