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.

Dynasty 200 SD - Provides the basic features that are required for most AC/DC TIG or Stick welding applications.

Wireless Remote Control Compatible
Improve productivity, eliminate clutter and cord tangles in the work area. Eliminate cord failure and associated downtime/repair costs and extend the operator's welding range without adding cord extensions. 

Lift-Arc™ starting provides x-ray clean welds in AC or DC arc starting without the use of high frequency.

Blue Lightning™ - High Frequency Arc Starter

For TIG non-contact arc initiation. Provides more consistent arc starts and greater reliability compared to traditional HF arc starters. Easy to set up and increases productivity.
Auto-Line Power Management Technology

Auto-Line Power Management Technology
Allows for any input voltage hookup (115-460 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.
AC and DC TIG Features

Extended AC balance (30-99%) controls the amount of oxide cleaning (amperage time in EN) which is essential for high quality welds on aluminum.

AC frequency (20-250 hz) controls the width of the arc cone and the force of the arc.

DC TIG provides exceptionally smooth and precise arc for welding exotic materials.
Stick Features (AC/DC)

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.

AC frequency control adds additional stability when Stick welding in AC for smoother welds.

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.
