Multi-Process Welding in a Smaller Package

Designed specifically to withstand harsh environments, the Dimension™ 650 multi-process welder from Miller Electric Mfg. Co. (Appleton, WI) offers an unbeatable combination of durability, output, efficiency and capability — all in a smaller, easier-to-handle package. The Dimension 650 provides both power-intensive output for heavy welding and carbon-arc gouging, as well precision arc characteristics designed for thin-metal welding. This compact and energy efficient machine features a tough, corrosion-resistant, all-aluminum case to protect against the environment. Exclusive protection input inductor protects against “dirty power” commonly found on jobs, preventing power fluctuations from affecting performance or reliability.

Adding to its durability is exclusive Wind Tunnel Technology™ that directs internal airflow to protect sensitive electronic components from dirt, dust and debris, significantly improving reliability. Fan-on-Demand™ operates only when needed, reducing noise, power consumption and the amount of airborne contaminants that are pulled through the machine. 3-1/4 in of ground clearance keeps the machine away from water, mud and dirt to protect interior components. The reduced size and weight of the new Dimension 650 makes it easier to handle while still providing the welding performance of a larger machine. Compared to the legacy Dimension 652, the new Dimension 650 is 3-1/2 times lighter and has a 40 percent smaller footprint, making it easier to move.

The Dimension 650 features high electrical efficiency that allows for more welding using 32 percent 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.

In other equipment applications, the stick and TIG-capable CST™ 280 Series is ideal for welding pipe and plate in power plant construction, petrochemical construction, maintenance and repair and shipbuilding applications. It is now available with an optional digital meter for more precise control when presetting of monitoring welding amperage. “With a digital weld meter, the welding operator can quickly identify both preset and welding amperage levels. This allows operators to know they are within specified parameters, so they can weld with confidence,” said Caleb Rosera, a product manager at Miller Electric. “Supervisors can also benefit from the technology, since they can visibly see that parameters are being met for the identified specifications of the job.”

The 41 lb machine is highly portable and can be easily moved around the shop or at a jobsite. The welder delivers up to 280 amps of output power and superior stick arc performance even on the most difficult-to-run electrodes like E6010. Adaptive Hot Start™ for stick arc starts automatically increases the output amperage at the start of a weld should the start require it — preventing the electrode from sticking. When TIG welding, Lift-Arc™ start provides TIG arc starting without the use of high frequency. A simple voltage-changeover switch saves time when changing primary voltage. The input voltage can be changed without removal from inverter rack or removal of machine case. The machine is rack mountable for protection, storage and transportation of multiple power sources using a single primary power cable.

The CST 280 Series comes standard with a 6 ft power cable and is fully compatible with Miller wireless remote control solutions — operators can work safer and faster up to 300 ft away from the power source. The elimination of cord tangles or failures helps to increase time and money savings, and precise operator control at the weld joint further improves overall weld quality.

Adding to their extensive welding safety and health offering, Miller Electric has also introduced a new line of protective eyewear with enhanced coverage for greater protection and shatterproof polycarbonate lenses in a wide range of styles for any application, including:

• Classic: Angle adjustable temples for personalized fit; lightweight for all-day comfort; frameless design for unobstructed view.
• Classic with Strap: Elastic strap holds glasses tight to face for improved protection; foam padding blocks debris; lightweight for all-day comfort.
• Spark™: Wraparound design enhances vision; flexible over-molded temples conform to user’s head; rubber nosepiece provides comfort and prevents slipping.
• Spatter™: Rubber temples and nosepiece provide extreme comfort and security; enhanced comfort and styling promote compliance; half-frame increases view.
• Slag™: Rubber temples and nosepiece provide extreme comfort and security; enhanced comfort and styling promote compliance; full-frame design optimizes protection.

A variety of lens options is also offered for customer needs, including Clear, I/O, Smoke, and Shade #3 and #5. All lenses feature anti-fog coating and high-quality optics. Clear offers general protection for a working shop environment. I/O (Indoor/Outdoor) lenses feature light shading with a mirrored finish to reduce glare in indoor and outdoor applications. Smoke lenses provide shade protection in outdoor applications. Shade #3 and #5 green IR lenses offer protection for cutting, brazing or soldering applications.
