Big Blue 500X Pro with ArcReach®
High-Output Power. Industrial-Grade Versatility.
The Big Blue 500X Pro with ArcReach is built for the toughest jobs. For remote sites, heavy fabrication, or critical structural work where downtime isn’t an option, it delivers up to 500 A of welding power, multi-process flexibility, rugged reliability, and safety-minded 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 reliable 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 compatible ArcReach feeders/remotes to reduce walking, improve safety, and increase arc-on time. Front-panel lockouts help prevent accidental changes on busy sites. -
Power & Efficiency
Generator power 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).
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
