Miller Dynasty 200 SD TIG Welder

Maximum flexibility - Miller Electric combines advanced inverter technology with Auto-Line™ technology, offering the most flexible AC/DC TIG/Stick power supply in the welding industry.

Advanced Squarewave arc for improved weldability on aluminum and magnesium using low power. Continuous high-frequency is NOT needed because of the advanced Squarewave arc.

AC frequency control range of 20 - 250 Hz provides control for a focused arc, resulting in better directional control to help produce desired arc/weld bead characteristics.

Fan-On-Demand™ cooling system only operates when needed.

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 45 lb 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 5-10 VDC when power source is not in use. This built-in circuit design eliminates the need for add-on voltage reducers.

Inverter-based, AC/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.

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.

Extended Balance Control range (30-90% EN) allows precise cleaning control and prolonged tungsten life.

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%.

Squarewave
The AC output of a power source that has the ability to rapidly switch between the positive and negative half cycles of alternating current.

Thermal Overload Protection
Internal components are protected from damage by thermal overload protection hich automatically shuts down the unit if duty cycle is exceeded or air flow and cooling are restricted.
