Maxstar® 200 TIG Welders

Industry standard - Miller Electric pioneered the Maxstar-type market, now we've perfected it. Maxstar 200 Series provides a solution for every user's needs; from simple to fully automated.

Maxstar 200 SD
  • Maxstar 200 SD
  • Maxstar 200 SD Front Panel

Three Models Available

Maxstar SD - Provides the basic features that are required for most TIG or Stick welding applications.
Maxstar DX - When the job demands greater control the DX provides pulse on/off, pulse frequency, peak % time, background amps, initial amps, initial slope time, final slope time, and final amperage control.
Maxstar LX - With the Automation Interface Connector, the integrator can quickly interface to the output disable, weld start/stop, gas start/stop inputs, valid arc, pulse lock out, and end of weld sequence outputs.

Wireless Remote Control Compatible

Improve productivity, eliminate clutter and cord tangles in the work area. Eliminate cord failure and associated downtime/repair costs and extend the operator's welding range without adding cord extensions. Learn more >>


Lift-Arc™ starting provides x-ray clean welds in AC or DC arc starting without the use of high frequency.

Stick Features (DC)

Tailored arc control (DIG) allows the arc characteristics to be changed for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010.
Hot Start™ adaptive control provides positive arc starts without sticking.
Low OCV Stick is a simple design that reduces open-circuit voltage to 5-10 VDC when power source is not in use. This built-in circuit design eliminates the need for add-on voltage reducers.

Blue Lightning™ - High Frequency Arc Starter 

For more consistent non-contact starts and greater reliability compared to traditional HF arc starters.

Auto-Line Power Management Technology

Auto-Line Power Management Technology
Allows for any input voltage hookup (115-460 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.

DC TIG Features

DC TIG provides exceptionally smooth and precise arc for welding exotic materials.
