Maxstar® 200 LX

Industry standard - Miller Electric pioneered the Maxstar-type market, now we've perfected it. Maxstar 200 Series provides a solution for every user's needs; from simple to fully automated.

LX Model: With the Automation Interface Connector, the integrator can quickly interface to the output disable, weld start/stop, gas start/stop inputs, valid arc, pulse lock out, and end of weld sequence outputs.

 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. No longer is there a concern if you have the correct machine for the shop or the job site.

Portable in the shop or at the job site - at 37lb the unit is easily moved from location to location.

Superior TIG/Stick arc performance on all input voltages. Even on the difficult-to-run electrodes like E6010.

Low OCV Stick is a simple design that 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.

Inverter-based, DC power source has state-of-the-art operator interface allowing the user extra set-up capabilities in a compact machine. Features more precise control of output parameters than traditional knobs and switches.

HF arc starting provides non-contact arc starting that eliminates tungsten or material contamination.

Lift-Arc™ start provides TIG arc starting without use of high frequency.

Programmable HF start parameters allows the operator to independently set HF starting conditions based upon electrode diameter and material thickness for each application.

Fan-On-Demand™ operates only when needed reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine.

Wind Tunnel Technology™ is an Internal air flow that protects electrical components and PC boards from dirt, dust, and debris, greatly improving reliability.

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

Adaptive Hot Start™ for Stick
Automatically increases output amperage at the start of a weld should the start require it and prevents the electrode from sticking and creating an inclusion.
