Miller True Blue Warranty Logo

  All Miller machines come with Miller True Blue three year warranty.

Miller MaxStar 700The Maxstar 700 provides the features you need in an advanced DC TIG/Stick inverter and the amperage capacity for even the biggest jobs. Add total AC arc shaping capabilities for the ultimate in control by stepping up to the Dynasty 700!

Main Features

  • Auto-Line™ allows for any input voltage hook-up (208-575 V) with no manual linking, providing convenience in any job setting.
  • NEW! Patented thread lock cable connectors and torch adapter are designed for high-amperage applications and feature1/4-turn locking threads.
  • Adjustable HF arc starting parameters - start amperage (amps), start time and start polarity (EP/EN). Optimize the arc start based on tungsten electrode diameter, material thickness and shielding gas.
  • Program memory features 4 independent memory levels per process (DC TIG and DC Stick) with last procedure recall to maintain established parameters in each memory.
  • Inverter-based, power source has state-of-the-art operator interface allowing the user maximum set-up capabilities. Features more precise control of output paramters than traditional knobs and switches.
  • Optional Automation interface kit has 28-pin interface to provide key automation controls and functions for plug and play system integration.
  • Fan-On-Demand™ cooling system only operates when needed.
  • HF arc starting provides non-contact arc starting that eliminates tungsten or material contamination.
  • Lift-Arc™ start provides TIG arc starting without the use of high frequency.
  • Low OCV Stick™ reduces open-circuit voltage to 10-15 VDC when power not in use.
  • Superior arc performance even on difficult to run electrodes like E6010.
  • 115 V auxiliary power provides 15 amps of 115 volt power to operate a Coolmate™ coolant system, grinder or other small power tool.
