Miller Showcases Dimension™ NT 450 Multiprocess Welder,
New High Volume MIG and TIG Solutions at FABTECH/AWS
APPLETON, Wis., August 19, 2005—Miller Electric Mfg. Co. will showcase no fewer than five new innovative and productivity-enhancing welding products the Fabtech International/AWS Welding Show in Chicago, November 13-16 in booth #6030.
These products, new since the AWS show in April, include new graphic designs for the Big Window Elite™ auto-darkening helmet and the Dimension™ NT 450 multi-process welding power source. The Dimension NT 450 features a new generation welding of technology designed for heavy industrial applications and offers the superior arc performance associated with Miller’s inverter products but with the reliability of its Dimension™ 452 three-phase welder.
Miller will also introduce revolutionary new MIG and TIG systems designed for high volume fabrication and manufacturing of aluminum, new systems for high volume MIG and TIG welding of ferrous metals and new diesel engine driven welding generators.
Dimension NT 450
The Dimension NT 450 provides a CC/CV welding output for MIG, Stick and Lift-Arc™ DC TIG welding, as well as air carbon arc gouging. It has a duty cycle of 100 percent at 450 amps/38 volts and an output amperage range of 5 to 500 amps and a voltage range of 10 to 38 volts. The low amperage output provides superior low-end TIG arc control, while the low voltage range provides excellent performance for short circuit MIG welding on thin materials or open root joints with beveled edges, such as pipe. A maximum open circuit voltage of 80 VDC delivers better starting performance for all welding processes.
Heavy industrial fabrication and construction operations that benefit from the Dimension NT 450’s arc performance include: pressure tank/vessel fabricators, pipe welders, shipbuilders, refineries and foundries, railcar manufacturers, construction/agricultural equipment manufacturers and heavy maintenance/repair operations.
“Many of the applications and companies in heavy industry require two or more different welding processes, and the Dimension NT 450 provides uncompromising multi-process arc performance. This overcomes the single biggest limitation of conventional welding equipment,” says Jeff Hietpas, Miller product manager. He adds that, “To give users peace of mind, the Dimension NT 450 transforms primary power using the same reliable ‘copper and iron’ design as our Dimension 452 power source.”
The Dimension NT 450 weighs 376 lbs., uses three-phase input power (230, 460 or 575 VAC) and features line voltage compensation to keep the welding output constant even if input power varies by ± 10 percent.
Hietpas notes that Miller developed the Dimension NT 450 because industrial customers wanted the arc performance of Miller inverters, which sets the industry standard for CC/CV multi-process power sources, but are not concerned about the size, weight and portability that is associated with inverter products.
With headquarters in Appleton, Wis., Miller Electric Mfg. Co. is a leading worldwide manufacturer of Miller and Hobart brand arc welding equipment and related systems for metalworking, construction, maintenance and other applications. Miller Electric is a wholly owned subsidiary of Illinois Tool Works Inc. (ITW), Glenview, IL. ITW is a diversified multinational manufacturer of highly engineered components, assemblies and systems.
