MILLER DYNASTY 210 AC/DC TIG WELDER
Miller Dynasty 210 AC/DC TIG/Stick Welder
Precision, flexibility and portability rarely coexist at this level — but the Miller Dynasty 210 delivers all three without compromise. Combining sophisticated inverter technology with the full suite of advanced Dynasty TIG features, the Dynasty 210 is the most capable and flexible AC/DC TIG/Stick power supply in the welding industry at this power class. Weighing just 21.3kg and accepting any input from standard 240V single-phase through to 480V three-phase via Auto-Line™ technology, it goes anywhere — from a workshop bench to a remote job site — without sacrificing a single degree of arc control or precision.
For aerospace technicians, precision fabricators, motorsport builders, defence contractors and infrastructure specialists who need Dynasty-grade performance in a truly portable package, the Dynasty 210 is the definitive choice.
True AC/DC TIG Performance in a Portable Inverter
The Dynasty 210 supports the full range of AC and DC TIG processes — including high-frequency and Lift-Arc starts, and full pulse capability (GTAW-P) — across a welding range of 1–210A DC and 2–210A AC on three-phase input. Whether you're running fine DC TIG passes on stainless steel tube, performing delicate AC TIG work on aluminium panels, or using pulse to control heat input on thin gauge exotic alloys, the Dynasty 210 delivers the arc quality and control that defines the Dynasty family.
Auto-Line™ Technology — Any Power, Anywhere (210–480V)
Auto-Line™ allows the Dynasty 210 to accept any single or three-phase input voltage between 210V and 480V with no manual linking or reconnection required. It will run from a standard Australian 240V single-phase supply, connect to 415V three-phase workshop power, and operate from generator sources — all without changing a single setting. This makes it uniquely versatile for operators who move between locations, work from vehicles or trailers, or need a machine that simply connects and performs regardless of available power.
Intuitive LCD Interface for Confident Setup
The Dynasty 210 features a clear, informative LCD display with on-screen explanations and dynamic images that guide operators through machine setup and parameter selection. Incorrect settings are harder to miss, and even less experienced operators can navigate the machine's advanced capabilities with confidence. An online simulator is also available, allowing operators to familiarise themselves with the interface before they even touch the machine.
Pro-Set™ — Eliminate Guesswork, Accelerate Setup
Pro-Set™ pre-set controls automatically calculate key welding parameters based on the operator's material and process inputs, eliminating guesswork and reducing setup time significantly. For precision environments where consistency matters — aerospace, defence, motorsport fabrication — Pro-Set™ ensures every setup starts from an optimised baseline, every time.
Program Memory and USB Port for Production Efficiency
Named weld programs can be saved, recalled instantly and transferred between Dynasty 210 units via the built-in USB port. For workshops running repeat jobs or operating multiple machines across shifts, this eliminates the time and variability of manual parameter re-entry — delivering consistent, repeatable results from the first arc to the last.
Stick Welding Capability Across All Input Voltages
The Dynasty 210 supports AC and DC Stick (SMAW) welding across a 5–210A range on all input voltages, including standard 120V single-phase at reduced output. For field operators who need occasional Stick capability alongside precision TIG work, the Dynasty 210 handles both without requiring a second machine.

Frequently Asked Questions:
What is the Miller Dynasty 210? The Miller Dynasty 210 is a professional portable AC/DC TIG and Stick inverter welder supporting 1–210A DC TIG, 2–210A AC TIG, pulsed TIG and 5–210A Stick. It weighs 21.3kg and accepts any single or three-phase input voltage from 210–480V via Auto-Line™ technology, making it the most flexible portable AC/DC TIG machine in its class.
Can the Miller Dynasty 210 run on single-phase 240V power? Yes. The Dynasty 210 accepts single-phase input from 208V to 480V via Auto-Line™ technology, including standard Australian 240V household or workshop single-phase supply — with no manual reconnection or linking required.
What is the amperage range of the Miller Dynasty 210? The Dynasty 210 offers a TIG welding range of 1–210A (DC single-phase) and 2–210A (AC three-phase), and a Stick welding range of 5–210A across all input configurations. On 120V single-phase, the TIG range is 1–150A DC / 2–150A AC.
How much does the Miller Dynasty 210 weigh? The Dynasty 210 weighs 21.3kg (22.7kg with the optional Cooler Power Supply), making it the most portable machine in the Miller Dynasty AC/DC TIG range.
What is the difference between the Miller Dynasty 210 and Dynasty 300? The Dynasty 210 is the entry point to the Dynasty AC/DC TIG range — lighter (21.3kg vs 25kg), lower maximum amperage (210A vs 300A) and without MIG/Flux-Cored capability. The Dynasty 300 Multiprocess adds MIG and Flux-Cored welding via CV output. The Dynasty 210 is the better choice for operators who need maximum portability and pure TIG/Stick performance; the Dynasty 300 Multiprocess suits those who also require portable MIG capability.
