Miller Introduces Syncrowave® 250 DX and 350 LX with Integrated Cooler

- Cool-On-Demand(TM) technology prevents torch damage

- Syncro-Start(TM) technology enhances arc starting precision

- First and only integrated cooler design to offer a three-year warranty

APPLETON, Wis. September 2, 2004-- Miller Electric Mfg. Co. has developed the industry's first AC/DC, TIG/Stick power sources to feature an optional integrated water cooler in the new Syncrowave® 250 DX and 350 LX. To prevent torch damage by monitoring coolant flow and temperature, the Cool-On-Demand(TM) feature operates only when needed, increasing reliability by reducing unnecessary pump and motor wear. Miller offers a three-year warranty on its integrated coolers while other manufacturers offer only a one-year warranty.

To significantly improve high-frequency TIG arc starting performance, Miller engineers developed Syncro-Start(TM)technology, which allows operators the choice of three different starting conditions to optimize starts to match tungsten diameter and material thickness. Other benefits include international dinse connectors that simplify torch and work hook-ups, a built-in consumables storage drawer for convenient access and built-in cable hangers to reduce workplace clutter and help prevent torch damage. In addition, a tilted operator interface with dual digital meters allows easy viewing of actual and preset voltage and amperage values.

The Syncrowave 250 DX and 350 LX feature AC/DC TIG, Pulsed TIG, Stick welding capabilities, Lift-Arc(TM) for DC TIG starts and adjustable DIG(TM) control and Adaptive Hot Start(TM) for better Stick performance. The Syncrowave 250 DX provides a welding range of 3 to 310 amps (200 amp/28 volts at 60 percent duty cycle) while the Syncrowave 350 LX provides a welding range of 3 to 400 amps (300 amp/32 volts at 60 percent duty cycle). Both Syncrowave models now offer the same excellent low-end arc performance- 3 amps.

Syncrowave applications include those in light and heavy manufacturing, precision metal fabrication and maintenance and repair industries, such as aerospace, automotive, tool and die, tube and pipe, shipbuilding and vocational education.

Reliable System and Three-Year Warranty

Cool-On-Demand technology monitors coolant flow and temperature to prevent torch damage due to overheating. By operating only when necessary, the Syncrowave's integrated water cooler offers increased reliability and reduces idle noise to create a more worker-friendly environment.

"The Syncrowave units are the most integrated machines and the easiest to use. My guys call it the plug, pour and go welder. Just plug it in, pour water in the cooler and start welding," states Scott Pickens of All Ways Metal.

While the industry standard is a one-year warranty on coolers, Miller offers the first and only three-year warranty on its integrated cooler design. "Customers asked for an all-in-one design. Miller wanted to provide them with not only an integrated package, but also a reliable system and worry-free warranty," says Brent Williams, Miller product manager.

Customized, Fine-Tuned Arc Starts

Because the Syncrowave is used for a wide variety of applications, Miller designed Syncro-Start technology. This patented arc start technology allows operators to customize and fine-tune arc starts based on tungsten diameter, material thickness and shielding gas.

"The guys in the shop love the fact that they can easily switch from AC to DC and that the HF changes automatically. We do a lot of switching between stainless and aluminum, so Syncro-Start technology is a great benefit and time saver for us," states Pickens.

Users have the option of choosing from three different starting conditions:

- Start #1, used for precision welding on thin materials at low amperages with small diameter electrodes.

- Start #2, the factory default, optimized for the industry standard 3/32-inch diameter tungsten electrode.

- Start #3, provides additional energy during the arc start, helping ignite larger diameter tungsten in heavy-duty or thick applications.

"With this technology, users can select the best arc start for the job. Syncro-Start technology makes it easy to achieve crisp, clean arc starts, regardless of the application," states Williams.

Reduction in Size

Recognizing that floor space is a heavily scrutinized expense in many different industries, the integration of the water cooler offers a more compact system with clean connections, reducing the required area that must be dedicated to welding equipment. The height reduction allows the Syncrowave TIGRunner® package to be tucked away under workbenches, providing an increase in work cell and manufacturing space. The configuration and positioning of component connections is now conveniently located at the front of the system providing necessary access. In addition, a water-cooled torch reduces size because it doesn't require the extra mass of an air-cooled torch to dissipate heat. Operators favor water-cooled torches because they provide better maneuverability, reduce fatigue and increase comfort by keeping the torch cooler.

Torch and Work Hook-Ups Simplified

Another new feature of both Syncrowave products is the addition of international dinse connectors. By providing dinse connectors instead of studs, the Syncrowave offers simplified torch and work hook-ups, eliminates the need for additional (peripheral) hoses and provides the ability to quickly change between a TIG torch and Stick electrode holder. Dinse connectors also address OSHA regulations, by helping shield users from hazardous energy.

To further clean up workspace areas, the Syncrowave 250 DX and 350 LX offer a built-in consumable storage drawer. This drawer allows the operator to store and readily access necessary consumables. In addition, built-in cable hangers conveniently fold out to allow all weld cables to be neatly stored, preventing torch or cable damage.

The Syncrowave product line is covered by Miller's True-Blue® three-year factory warranty.
