Compatibility Snapshot
- The March 2026 data sheet is Deltaweld 350-specific and separates the 350 package list from the broader Deltaweld 350/500 catalog route.
- ArcConnect is standard on Deltaweld 350; selected stock numbers add meters, 14-pin receptacle, Insight, or 575 V input.
- Accu-Pulse requires Intellx Pro or Intellx Elite feeders; Versa-Pulse, high-deposition MIG, RMD, and XR Plus push-pull gun compatibility require Intellx Elite.
- XR Plus push-pull guns are only compatible with Intellx Elite feeder, Intellx Elite ROI / remote wire drive, or Intellx Elite Swingarc boom-mounted feeder.
- Use the exact package or power-source stock number before ordering 14-pin, ArcConnect, Insight, cooler, cart, or dual-wire accessory parts.
