The Miller Dynasty 400 Auto-Line 380–575V delivers serious TIG performance in a compact, high-end inverter. It suits workshops and heavy fabrication jobs that demand precision, control, and reliability. With an output range of 3–400 amps, it handles everything from thin material to aluminium up to around 16 mm.

This machine gives you full control of the arc. Adjust AC balance, frequency, and amperage independently. Fine-tune cleaning action and penetration with ease. The result is cleaner welds, better bead appearance, and stronger results—especially on aluminium.

Multiple AC waveforms let you tailor the arc to the job. Choose from squarewave, soft squarewave, sine, or triangular. Increase travel speed. Reduce heat input. Improve puddle control.

Auto-Line™ technology makes setup simple. Plug into any 380–575V three-phase power without manual linking. Get consistent performance even when power conditions vary.

Starts stay sharp and clean with high-frequency arc starting. High-speed pulse improves stability and reduces distortion on thinner materials. Save your settings. Repeat results every time.

The interface stays clear and easy to use. No guesswork. No wasted time. Just fast setup and consistent output.

If you want power, precision, and total control in one machine, the Dynasty 400 Auto-Line stands at the top. Built for professionals. Designed to perform.
