907747003 - Miller Deltaweld 350 MIG Welder 208-230/460V with ArcConnect, 14-Pin & Insight Core

Industrial Precision with Digital Intelligence

The Miller Deltaweld 350 (907747003) represents a significant leap forward in industrial MIG welding technology, blending robust power delivery with advanced digital monitoring capabilities. Designed for heavy manufacturing, structural steel fabrication, and transportation industries, this 350-amp power source operates on 208-230/460V 3-phase power. It is engineered to simplify complex welding operations while providing actionable data to improve shop floor efficiency.

Integrated Insight Core™ Technology

This model comes standard with Insight Core™, an internet-based welding information solution. Insight Core gives production managers visibility into their operations by tracking arc-on time and identifying welding costs. By simply connecting the machine to the internet, users can access secure data dashboards on any web-connected device, allowing for data-driven decisions that enhance productivity and reduce operational expenses.

Versatile Connectivity: ArcConnect™ & 14-Pin

Flexibility is a hallmark of the Deltaweld 350. It features both the next-generation ArcConnect™ receptacle and the traditional Miller 14-Pin receptacle. ArcConnect utilizes high-speed signals to improve weld performance and allows point-of-use controls to be located at the feeder, specifically designed for Miller Intellx™ feeders. Meanwhile, the standard 14-pin connection ensures backwards compatibility with older Miller wire feeders, allowing facilities to upgrade their power sources without immediately replacing all ancillary equipment.

Advanced Reliability Features

Miller has incorporated their proprietary Wind Tunnel Technology™ into the Deltaweld 350. This internal airflow design routes air through a dedicated tunnel, protecting sensitive electrical components and PC boards from dirt, dust, and debris. Coupled with Fan-On-Demand™, which operates the cooling system only when necessary, the machine runs quieter, consumes less energy, and pulls in fewer contaminants.

Simplified Operation

For operators, the EZ-Set feature removes the guesswork from parameter setup. By simply selecting the material thickness, the machine automatically adjusts to the optimal settings, reducing training time and ensuring consistent weld quality across different operators. Whether used for standard MIG or Flux-Cored processes, or upgraded for Pulsed MIG with an Intellx Pro feeder, the Deltaweld 350 is a versatile asset for any industrial environment.
