Description

Miller Maxstar 400

EXCEPTIONALLY SMOOTH & PRECISE ARC PERFORMANCE

The Miller Maxstar 400 is an advanced TIG and Stick welding solution, delivering consistent, precise arc performance for demanding applications such as tube mills, precision metal fabrication, and exotic material welding. Designed for professional welders, this machine provides robust power with reliable features like Auto-Postflow, Program Memory, and Wind Tunnel Technology™. Whether you’re working with exotic materials or performing high-quality pipe fabrication, the Maxstar 400 ensures superior arc performance and control.

Key Features:

  • DC TIG Features:
    • Exceptionally Smooth & Precise Arc: Ideal for welding exotic materials, delivering a stable and precise arc.
    • DC Pulse Technology: Increases puddle agitation and stability, enabling higher travel speeds and reducing heat input.
  • DC Stick Features:
    • DIG Control: Tailors arc characteristics to the specific electrode and application.
    • Hot Start Adaptive Control: Ensures positive arc starts without electrode sticking.
  • Advanced Arc Initiation Options:
    • Lift-Arc™ Starting: Provides AC or DC arc initiation without the use of high frequency.
    • Blue Lightning™ HF Arc Starter: Non-contact arc initiation that delivers reliable starts every time.
  • Cooler-On-Demand™:
    • Operates the cooling system only when needed, reducing noise, energy use, and pulling of contaminants into the machine.
  • Fan-On-Demand™:
    • Operates the cooling fan only when needed, reducing energy consumption and airborne contamination.
  • Program Memory:
    • Nine independent memory programs to maintain and save specific parameters.
  • Auto-Postflow:
    • Automatically calculates postflow time based on the amperage setting to optimize gas coverage and protect the tungsten from contamination.
  • Wind Tunnel Technology™:
    • Protects internal components from contamination, extending the lifespan of the machine.
  • Cooler Power Supply (CPS):
    • A dedicated 120V receptacle to power the Coolmate™ 3.5 cooler.
  • Meter Calibration:
    • Allows meters to be calibrated for certification.
