Item Details

  • Miller® Deltaweld® 452 MIG Welder Power Source operates in 3-phase and features digital meters that are easy to read. Welding machine is rated at 230/460/575 V and has an operating frequency of 60 Hz. Welder Power source is used in heavy industrial applications such as sheet metal fabrication, truck and trailer manufacturing, ship and boat building, heavy equipment manufacturing, structural steel fabrication and more.


  • Superior arc welding performance with MIG welding
  • Internal digital voltage control (DVC) enables operator to preset weld voltage before striking an arc
  • Line voltage compensation ensures consistent weld performance by keeping output power constant even if primary input power varies by ±10%
  • Power efficient for exceptional value and return on your investment
  • Two positive output terminals provide high/low stabilizer selection
  • Allows operator to optimize arc performance
  • Thermal overload protection light indicates power shutdown
  • Helps prevent machine damage if the duty cycle is exceeded or airflow is blocked
  • Power cord strain relief provided for your convenience at installation
  • Digital voltmeter and ammeter are easy to read, even at 30 ft
  • Simple control panel provides easy, efficient operation
  • 14-pin receptacle provides quick, direct connection to Miller 14-pin wire feeders and accessories
