Welder Generator Provides Superior Arc Performance

Miller Electric has introduced the Big Blue 300 Pro CC/CV engine-driven welder generator. With 12kW of generator power and a 20 to 410A welding output, the Big Blue 300 Pro is said to provide superior arc performance and stability, along with durability for reliable operation in demanding conditions. Suitable for pipe and construction contractors, as well as MRO and fabrication professionals, the Big Blue Pro 300 is available with CAT, Deutz or Perkins diesel engines for 1,800rev/min operation, fuel efficiency and 71dBa sound levels at maximum output.

As with all Big Blue models, the Big Blue Pro 300's circuit board is protected by Miller's Vault, a hermetically sealed aluminum case that is impenetrable to dust, salt and moisture. To ensure performance and reliability in high-heat applications, Miller rates its engine drives at 104F. Said to give excellent arc performance in all processes (TIG, Stick, MIG, flux cored and carbon arc gouging), the Big Blue 300 Pro features improved arc starts and stability over the Pro 300. It provides tailored arc control (DIG), which allows the operator to change arc characteristics for specific applications and electrodes, such as 7018 and 6010.

Weighing 1,100lb with CAT or Perkins engines and 1,208lb with a Deutz engine, the Big Blue 300 Pro's 32 x 26.25 x 56in size allows it to fit sideways in a standard pickup truck's bed, leaving extra room for tools and supplies. It features a low fuel shutdown that will shut down the engine before it runs out of fuel, making restarting easy and eliminating the need to re-prime the engine. High-temperature and low oil pressure shutdowns protect the engine, while hour- and oil- change-interval meters make it easier to track maintenance requirements.

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.
