Described by Miller as a compact and energy efficient machine, it features a corrosion-resistant, all-aluminum case to protect against the environment and a protection input inductor that protects against "dirty power" commonly found on jobs. This prevents power fluctuations from affecting performance or reliability, claims Miller.
The company's Wind Tunnel Technology directs internal airflow to protect sensitive electronic components from dirt, dust and debris. A Fan-on-Demand feature operates only when needed, reducing noise, power consumption and the amount of airborne contaminants that are pulled through the machine.
The Dimension 650 features high electrical efficiency that allows for more welding using 32 per cent less power. Its full-load welding draws fewer than 50 amps of power, so the machine can function properly in a wider variety of locations.
The machine's gouging mode provides 800 amps of usable power. A full 650 amps of power at 100 percent duty cycle makes the Dimension 650 ideal for heavy gouging with 3/8-in. carbons and the exceptional short-arc MIG performance offers the necessary precision for welding of thin metals — with less risk of distortion or burn-through. The machine also provides excellent Stick and Lift-Arc TIG welding capabilities, and easier fine-tuning of the arc makes superior performance possible even on tough-to-weld materials and out-of-position applications. A Subarc (SAW) mode provides capability to retrofit into non-digital Subarc applications and a Flux-Cored Arc Welding (FCAW) mode provides reliable welding performance for wires commonly found in infrastructure construction.
