An up-close look at the Precision Master plasma cutter from Advanced Cutting Systems.
Although many hvacr and sheet metal machinery companies save their big new product announcements for the AHR Expo in January, many manufacturers use Fabtech to show off improvements in existing products or build anticipation for future developments. Among the products on display:

Hanover, N.H.-based Hypertherm was showing off its new G3 Series of manual cutting systems. The Powermax1650 - the latest addition to the lineup - offers greater speed, longer parts life and lower overall operating costs, according to company officials. The unit's maximum cut capacity is 1.5-in., and it delivers gouging capabilities at a rate in excess of 22 lbs. per hour. The 1650 also features an active pilot arc for cutting expanded metal or grating, a patented easy torch removal system, and Auto-voltage? input sensing of 200 to 600 volts, three phase. No manual linking is required.

The company was also displaying new power supplies, torches and cut samples from Hypertherm's mechanized systems, including the Hypertherm HT2000, HT4400 and HD4070.

Advanced Fabricating Machinery used its booth to demonstrate several products, including the Stierli-Bieger Ram Bender Model 300 HE. The mechanical/hydraulic horizontal bending machine uses maximum ram speed throughout the length of the stroke and can produce 600 bends per hour.

Advanced Fabricating Machinery also showed the Stierli-Bieger Plate Shear 250, a mechanical flat shear that uses a working power of 77 short tons throughout the full stroke length. The cutting angle and blade gap can be adjusted to suit a variety of specifications and allows for the shearing of small parts.

Trumpf Inc. used Fabtech to debut its new TC L 2530 Plus laser cutting machine. Company officials say its use can result in productivity gains of up to 40%. The four- by eight-ft. machine uses new motion technology to allow the laser head to accelerate quickly. Called Sprint Axis, the technology increases "beam on" time. Also on display at Trumpf's large booth were the Trumpf Qualifier visual inspection tool, series C and V press brakes, power tools and a laser marking machine.
