Quantity: In Stock


The Miller Maxstar® 210 STR is a portable 210 amp stick and Lift-Arc DC TIG welder. Weighing only 36 pounds, the Maxstar® 210 STR provides up to 210 amps of code-quality DC output, delivering enough power to weld with 1/8 and 5/32 inch diameter E6010 and E7018 electrodes.

The Maxstar 210 STR features Auto-Line™, which allows you to plug into any outlet ranging from 115 to 460 volts, single or three-phase, 50 or 60 hertz, without manual re-linking. Low OCV (Open Circuit Voltage) in the Stick mode, reduces open circuit voltage to 13 volts when not in use. Other features include Adaptive Hot Start and Adjustable Dig for Stick, Lift Arc for TIG, and remote facilities for easy remote hook up.


  • Stick (SMAW)


  • Heavy Industrial Applications
  • Petro/Chem Fabrication
  • Mechanical Contractors
  • Shipboard Installation/Repair
  • Mining
  • Process Plant Piping
  • Maintenance and Repair


  • Dual schedule allows operators to switch welding parameters for specific electrodes without readjusting the machine, minimizing downtime and enhancing quality.
  • DIG control allows the arc characteristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth running electrodes like E7018 and increase the DIG setting for stiffer, more penetrating electrodes like E6010.
  • Hot Start™ adaptive control provides positive arc starts without sticking.
  • Stick-Stuck detects if the electrode is stuck to the part and turns the welding output off to safely and easily remove the electrode. Menu selectable.
  • Upgradeable and expandable. Front panel memory card data port provides the ability to easily upgrade software and expand product features.
  • Pro-Set™ feature (professional settings) eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of pre-set controls. Simply select the feature and adjust until Pro-Set appears on the display. The Pro-Set feature is available for Balance, Frequency, Pulse, and DIG parameters.
  • Lift-Arc™ start provides TIG arc starting without the use of high frequency.
  • Sleep timer conserves electricity. This programmable feature will power down the machine if it sits idle for a specific time.
  • Auto-Line™ provides state-of-the-art flexibility by automatically connecting to 208-575 VAC, single- or three- phase power without removing the covers to re-link the power source. No longer is there a concern if you have the correct machine for the shop or the job site.
  • Meter calibration. Digital meters can be calibrated to a standard device for certification.
  • Wind Tunnel Technology™ protects internal electrical components from airborne contaminates, extending the product life.
  • Fan-On-Demand™ power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminates pulled though the machine
  • Thermal Overload Protection - Internal components are protected from damage by thermal overload protection which automatically shuts down the unit if duty cycle is exceeded or air flow and cooling are restricted.
  • Wireless remote compatible - fully compatible with Miller wireless remote control solutions so you can work the way you want
