ESAB Introduces the Continuous Cleaning Downdraft Table

ESAB Cutting Systems introduces its next generation of self-cleaning cutting tables designed to reduce operating cost and improve efficiency. The simple design of these continuous cleaning downdraft (CCD) tables pushes slag and small parts to the end of the table for easy clean out. This reduces down-time between cuts, because the table does not require a separate cleaning cycle, and reduces maintenance labor because the table cleans itself. Parts are removed quickly with less fouling from slag.

The CCD table works on a simple principle. A heavy duty drag chain pulls a plow across the floor below the cutting surface. This simple, sturdy blade design can run under the table even while plasma or oxy-fuel cutting. The endless loop chain arrangement allows the plow to continuously run in the same direction, with no complicated reversing mechanism and no reversing switches or electrical control systems. The standard AC motor and rugged gearbox operate in only one direction.

As a self cleaning table, the CCD reduces operating costs by eliminating periodic system shutdown while the table is cleaned. It also eliminates the need to remove burning bars or lift and empty slag trays. Slag and small parts are automatically plowed to the end of the table for easy cleanout. For high volume applications or extended table lengths, the frequency of cleaning can be increased by installing additional plow blades on the chain. The simple, continuous chain design permits multiple blades without any effect on performance or construction.

Designed for plasma and oxy-fuel cutting of materials up to four inches thick, the CCD table provides efficient fume capture through a system of mechanically actuated zone dampers. Because fumes are exhausted from both sides of the table, plates do not need to be biased toward one side.

The modular design of the CCD table allows a variety of table sizes to be assembled from common modules. The table is shipped in modules and easily bolted together on site. This reduces lead times and shipping costs, since no oversize loads are required.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
