Acer Veriton series supplemented by business PC platform with Clarkdale
The desktop S680G is available from 700 euros. For 800 euro you get up in April in the M680 Micro-tower chassis. Chipset is in any case, Intel's new Q57 Express.

Acer has updated its PC line for business. The two new models lead Intel's newest processor core models i3, i5 and i7 a (code name Clarkdale). The Veriton M680 at prices from 799 euros sitting in a micro-tower chassis that can S680G for 699 euro entry to be placed under the monitor as a desktop.
The case designs allow different stages of development: The Mini-Tower features two 5.25-inch bays and six places for 3.5-inch drives. The desktop can hold only one large or four small ones. There are no differences in the number of ports, however: in both cases are about ten USB 2.0 ports (four in front), VGA, DVI and serial port. Also both have a card reader.
The basic configuration is also identical: installed, the Intel Q57 Express chipset. The customer has the choice between Intel CPUs from Pentium to Core i7 with and without vPro technology. The main memory (four DIMMs, DDR3, 1066 MHz or 1333) can expand to a maximum of 16 GB. What the above entry level configuration as required, not Acer.
SATA disks can be mirrored by the RAID principle. There are the levels 0, 1, 5 and 10 and Intel Rapid storage are available.
The operating systems of Windows 7 and Acer offers XP with Service Pack 3, Linpus Linux X and FreeDOS. On Windows, you also get Acer's Veriton Dientsprogramme Control Center, Acer Acer Security Suite and Client Manager.
The delivery of two new models will start Acer in April 2010.

Abstract: The principle of AC and DC welding power and features to achieve, and from AC-DC inverter welding power source technology, digital control technology, intelligent control technology to the study describes in detail the current situation, pointing out that the AC and DC arc welding power along the high-performance digital and intelligent direction of the trend.

Aluminum and its alloys commonly used frequency sine wave AC TIG welding, arc welding power supply but poor stability, positive and negative electrodes can not be used for basic arc. In particular, it demands higher for some welding work, such as aluminum welding thin pieces of small current, one-side welding forming, welding and other high strength requirements, are difficult to obtain satisfactory weld quality. With the high-power semiconductor devices and power technology development, successfully applied in China in recent years, AC and DC arc welding process, and to develop and produce the corresponding arc welding power.
AC and DC arc welding is an ideal thin aluminum arc welding method, which not only can control the weld penetration, but also can improve the welding efficiency. AC and DC TIG function which is best suited aluminum and aluminum alloy, magnesium and magnesium alloy welding, its regulatory function with aerosol can effectively eliminate the surface oxide film; weld forming a good, bright surface appearance.
