Power and Performance
Power Input: 380/460 V, 50/60 Hz or 575 V, 60 Hz, Three Phase
Rated Output: 650 A at 44 VDC, 100% Duty Cycle
Output Range: 15–815 A, 10–65 V
Net Weight: 158 lb (71.7 kg)
The Dimension 650 delivers high-quality performance with advanced arc control for precise adjustments, making it suitable for various welding needs, including thin metal welding with its short-arc MIG capabilities.
Durability and Reliability
Built for tough environments, the Dimension 650 features:
- Robust Construction: A durable, corrosion-resistant, all-aluminum case protects internal components.
- Wind Tunnel Technology™: An internal airflow system shields electrical components and PC boards from dirt, dust, and debris, significantly increasing reliability.
- Fan-On-Demand™: The fan operates only when needed, reducing noise, energy consumption, and airborne contaminants.
- Elevated Design: 3.25 inches of ground clearance helps keep the machine away from water, mud, and dirt.
Compact and Lightweight
Weighing only 158 lb (71.7 kg), the Dimension 650 is significantly lighter and more compact than previous models, making it easier to maneuver on job sites. It also occupies 40% less floor space.
Energy Efficiency
The Dimension 650 boasts high electrical efficiency and an excellent power factor, allowing for more welding with less energy. At 460 V input, it consumes only 43 A at rated load and can operate on a 50 A circuit. Four Dimension 650 units can run simultaneously on a 200 A circuit, consuming less amperage than three older models.
ArcReach® Technology
Optional ArcReach technology provides cord-free remote voltage control directly from the wire feeder or remote, eliminating the need for control cords. This enhances safety and productivity by allowing operators to adjust welding parameters without returning to the power source.
- Benefits of ArcReach:
- Reduced downtime and maintenance costs associated with damaged control cords.
- Improved safety by minimizing the need to travel across job sites to adjust settings.
- Automatic process selection simplifies setup.
- Enables remote control of preheating and tempering applications up to 600°F (315°C) using induction heating.
User Interface and Controls
Digital Meters: SunVision™ digital meters provide clear visibility of welding parameters from various angles, even in direct sunlight.
LED Process Indicator: Clearly identifies the active welding process from a distance.
14-Pin Receptacle: Features Auto-Remote Sense™ for easy connection of remote controls and wire feeders.
Arc Control: Provides fine-tuning of arc characteristics for SMAW and wire welding, allowing adjustments for different materials and welding positions.
Additional Features
- Remote In Use Indicator: Confirms when a remote device is connected.
- Auto-Bind: Establishes a secure communication link between the power source and wire feeder.
- Fleet Compatibility: ArcReach-equipped equipment works with non-ArcReach equipment, but full benefits are realized with the ArcReach system.
- Front-Mounted Power Switch: Easily accessible for convenience.
- Rear Panel: Provides 120 V auxiliary power for electric tools.
- Durable Welding Cable Connections: Serrated lugs ensure secure connections.
