Miller Dynasty 400 Complete Package

The Miller Dynasty 400 Complete Package is a new AC/DC TIG welder rated at 400 amps output, capable of welding 5/8-inch material and built to handle mild steel, stainless, and aluminum on the same machine. Auto-Line technology accepts any input voltage hookup from 208 to 575 volts, single or three phase.

What it is for

An integrated cooler power supply is built into the case, reducing the number of loose power cords on the shop floor compared to a separate water cooler unit. Advanced waveform technology and full balance control are aimed at clean, controlled aluminum welds rather than general-purpose fabrication alone.

What to check before buying

• Power input: accepts 208, 220, 230, 240, 460, or 575 volts depending on your shop's service.
• Duty cycle: rated 60 percent at 300 amps on three-phase power.
• Weight: 367 pounds, a shop-floor machine rather than something moved often between sites.

What processes does it support? Stick, TIG, and air carbon arc cutting and gouging.

How many memory settings does it have? Nine program memory settings for saved weld parameters.

What is the warranty? This Dynasty package carries Miller's standard 3-year manufacturer's warranty.

Blue Lightning high frequency and dig and hot-start stick capabilities round out a machine built for shops that move between aluminum TIG work and heavier stick or gouging jobs in the same day. welding equipment
