Ws 315a Argon Arc Welding Machine - China

price: contact company for price

A new generation TIG welding machine manufactured by Jinan Aohua co.,

ltd. adopts the advanced soft switching inverter based on the core

fitting of imported IGBT and microcrystal magnetic cores with the 20KHZ

inverter frequency. The product owns high load duty cycle with arc

igniting current and current thrust control function. It owns the

advantages of automatic compensation function for voltage fluctuation,

stable arc, even weld crater, little splash and good weld formation. And

on the other hand, it first applies the digital circuit control

technique for the purpose of quality of welding, which not only reduces

the weight and volume much and improves the portability but simplifies

the operation of facility, getting good arc ignition and welding

performance to improve the precision of welding.

Due to adopting the digital circuit control, the pre-welding set value can be displayed by the number. The actual value is displayed during the welding, and the value is locked automatically after welding, which makes convenience for presetting and control of welding criterion.

The way of arc striking is the HF arc striking. It adopts one kind of new electric HF arc igniter with strong HF discharge. The unique property improves the adaptability of welding machine, and even connecting long cable, it can keep good arcing performance. Its top inverting frequency of 20KHZ reduces the current fluctuation influence for arc much, which makes arcing and arc static current very low (20A). The arc burns steadily and quietly with dense arc and small heat affected zone, especially suitable for welding thin metal plates. Considering all aspects of factors?influence for the welding machine in designing, the advanced design is adopted in some minutiae. The shell adopts the engineering plastic, and the die is shaped by single-pressing with prominent edge for protection; the inner bare line adopts the insulating varnish with high insulating strength for protection that can cope with rugged environment. In addition, fully considering the economy of welding machine use in the design, the power consumption efficiency of all digital TIG welding machine reaches 90%, and the power factor reaches 0.89. Finally these serials advanced design passes the strictest test and reaches the following standard: CCC- meets the GB15579.1-2004 standard; shell protection grade: IP21S, suitable for field use, insulation grade: F, waterproof and preventing foreign materials.

  • Business Description: Founded in 2003, Jinan Huaao Welding Machine Co., Ltd is a hi tech enterprise specializing in producing high power inverter welding machine. The company employs 70 people, including 20 technical personnel with technical secondary school or junior college degree, has established sound design, development, production and marketing system, and formed solid strength. The company has established partnership with Shandong University Scientific Research Institute, and develops new products constantly through independent innovation and launches a number of new products every year. The company adopts modern enterprise management system, and has passed ISO9001: 2000 Quality Management System Certification, realizing whole process control from product development and production management, quality assurance, marketing to after sales service. The company was rated as Contract stressing & Promise keeping Enterprise by Jinan Municipal Peoples Government for two successive years. Its seven serial products were awarded "CCC" Certificate issued by China Quality Certification Center.

    All the companys products adopt soft switch and full bridge IGBT technology, and cover seven series including internationally advanced NBC series IGBT inverter carbon dioxide gas welding machine, ZX7 series IGBT inverter manual arc welding machine, LGK series IGBT inverter air plasma cutting machine, MZ series IGBT inverter automatically submerged arc welding machine, WS series IGBT inverter welding machine, WSM inverter DC welding machine, WSME AC DC pulse inverter welding machine seven series, In particular, WSM series and WSME series have realized digital and been put into production since 2006. In January 2008, the company successfully developed the ZX7 2000A inverter DC arc welding machine and LGK 250A inverter air plasma cutting machine, with technological innovation ranking the first in China. And, we also could produce the welding machine with input voltage DC 250V, DC 550V, AC 660V.

    In 2007, the Company developed a new generation of energy saving inverter welding machine, which is waterproof, anti mist, anti corrosion, and anti electronic jamming, to meet the requirements of poor working conditions of global shipbuilding industry. These products have significant effect in use and won high appraisal of customers.

    In 2010, Huaao welding make a further machine technology development. Basing on the market and customers request, Huaao welding redesign and assemble the machine connection to diesel generator for special power supply situation. No load voltage below 25V is designed on MMA machine for more safe working condition. New technology for cellulose electrode welding on Huaao MMA machine will be much better than other at whole market of Huaao.

    In todays global economic integration, Huaao Welding Machine Co., Ltd will continue to implement the quality principle of "to win by quality, to serve customers with faith, to satisfy customers with warmth," taking quality as enterprise s life, developing enterprise based on honesty and trustworthiness, and taking users needs as the goal. We are looking forward to cooperate with domestic and foreign merchants, to continuously expand the development space of products and the industry, and promote the development of welding technology of China!
