Miller Big Blue 500XPro with Arc Reach Diesel Engine Driven Welder-Basic Upgrade
Big Blue 500X Pro with ArcReach®
High-Output Power. Industrial-Grade Versatility.
The Big Blue 500X Pro with ArcReach is built for demanding worksites. For remote projects, heavy fabrication, or critical structural welding where uptime matters, it delivers up to 500 A of welding power, multi-process flexibility, and productivity-focused controls.
Why It Stands Out
-
Massive Weld Output
100% duty cycle at 400 A / 36 V, 60% at 450 A / 33 V, and 40% at 500 A / 30 V. High open-circuit voltage for confident arc starts. -
Multi-Process Capability
Stick (SMAW), Pulsed MIG (GMAW-P), MIG (GMAW), Flux-Cored (FCAW), DC TIG (GTAW), RMD, and Air Carbon Arc (CAC-A). -
ArcReach® Productivity
Adjust parameters at the weld with ArcReach wire feeders/remotes to reduce walking, improve safety, and increase arc-on time. Front-panel lockouts help prevent accidental changes. -
On-Site Power
Generator output for tools and site needs: three-phase 380–415 V (approx. 21 kW peak / 15 kW continuous) and single-phase 240 V (approx. 4 kW continuous). -
Enhanced Safety Features included with this model
Equipped with an Emergency Stop, Double Pole Battery Isolator, and Lockout Device for maximum operator and site safety.
Ideal For
- Structural steel, heavy fabrication, pipeline and vessel work
- Maintenance & repair in remote or off-grid locations
- Construction and rental fleets needing robust, low-maintenance equipment
