In Southeast Asia, the Miller® Deltaweld® 402, Deltaweld® 602 and Deltaweld® 852 are popular MIG welding machines that are known for their outstanding reliability and superior arc welding performance. The Deltaweld® series is used in many heavy industrial applications such as heavy equipment manufacturing, truck and trailer manufacturing, and pressure vessel fabrication, just to name a few.

With advancements in technology and the need to meet the expectations of new welders and businesses, Miller Electric Mfg. LLC is launching a new Deltaweld® series to replace the legacy Deltaweld® 402/602/852.

The New Deltaweld® Welding Machines

The new Deltaweld® series comes in two models: Deltaweld® 350 and Deltaweld® 500. The welding machines operate on 380/400VAC, 50/60Hz, 3-phase input power, which is common in Southeast Asia.

  • The Deltaweld® 350 has a rated output of 350A at 60% duty cycle.
  • On the other hand, the Deltaweld® 500 has a rated output of 500A at 100% duty cycle. The Deltaweld® 500 also has a dedicated constant-current gouge mode.

Because the new Deltaweld® 350 and Deltaweld® 500 are designed based on the latest inverter technology from Miller®, metal fabricators will experience exceptional arc welding performance and significant power savings as compared to the legacy Deltaweld® 402/602/852.

The New Intellx™ Wire Feeders

Accompanying the latest Deltaweld® 350 and Deltaweld® 500 are three newly-designed wire feeders: Intellx™, Intellx™ Pro and Intellx™ Elite. These wire feeders will connect to the Deltaweld® via ArcConnect™, a next generation communication from Miller®. ArcConnect™ utilizes high speed signals to improve weld performance and allow point-of-use controls to be located at the feeder’s interface. This means that welders no longer need to walk back to the welding machine to make parameter or process changes.

  • The Intellx wire feeder offers basic MIG welding and Arc Control. Arc Control allows welders to finetune the welding arc so they can produce better welds.
  • The Intellx™ Pro wire feeder adds EZ-Set and Accu-Pulse®. EZ-Set lets welders quickly get into a good starting parameter by showing them what material thickness they should be welding on. This reduces welder training time and gets them into production quicker. The Accu-Pulse® technology is a pulsed MIG process developed by Miller®. When compared to traditional MIG welding, the Accu-Pulse® process delivers a more forgiving arc with a 28% wider operating window. Consequently, even inexperienced welders can produce better welds with less rework and spatter in production. The Intellx™ Pro also has two memory slots and inbuilt steel and stainless-steel welding programs.
  • Lastly, the Intellx™ Elite wire feeder introduces eight memory slots and advanced settings such as Locks & Limits and Weld Sequencing. There are also more inbuilt welding programs within the Intellx™ Elite, notably for aluminium and nickel. In order to make it easy for welders to quickly setup and operate this fully-featured wire feeder during production, the Intellx™ Elite is equipped with a full-colour LCD screen.
