Zx7 200 Real Metal Manual Arc Welding Machine - China

price: contact company for price

CE certificated machine.

ZX7 series welders are general MMA arc welder which adopts the latest pulse width modulation (PWM) technology and the insulated gate bipolar transistor (IGBT) power module. It can change work frequency to medium frequency so as to replace the traditional hulking work frequency transformer with the cabinet medium frequency transformer. Thus, it is characterized with portable, small size, low consumption and etc.

ZX7 series have excellent performances: constant current output makes welding arc more stable; fast dynamic response speed reduces the impact from the arc length fluctuation to the current; accurate stepless current adjustment and pre-setting function. There are also some automatic protection functions for under voltage, over current, over heat, etc. inside the welders, when the problems listed before occurred, the alarm on the front panel is light and at the same time the ourput current will be cut off. It can self-protect and prolong the using life and greatly improved the reliability and practicability of the welders.

ZX7 series welders can also realize TIG operation. While MMA operation, if the electrode touches workpiece over two seconds, the welding current will drop to the minimum current automatically to protect the electrode. While TIG operation, the minimum current will be outputted firstly until the arc is ignited by lifting method, the output current will rise to the preset value, which can protect the electrode. At the same time, the arc force and hot start will be provided with MMA operation.

This machine is with the real 200A/28v output power for welding work.

Plug is with size of 3050.

  • 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!
