Wsm 315a Argon Arc Pulsed Welding Machine - China

price: contact company for price

WSM series digital welding machine produced is changed to “ARV” (

microcomputer controller) control from the analog control of traditional

inverter welding machine ( refers to the main part which influences

welding machine) .

Centralized Treatment of all welding data by Digital “ARV”. Control and monitor all the welding process by digital, make reaction for change of any welding process quickly. The monitoring system makes the digital comparison and adjustment timely for the actual welding parameters and the setting parameters, so the machine shows the incomparable welding accuracy so far.

Outstanding characteristic of WSM digital TIG welding machine:

1. Structure aspect

● Volume and weight ( WSM- 400 main engine only 38kg) WSM series welding machine adopts the digital micro- processing technology combining with the high frequency converting technology, and decreases 20% electronic components.

● Fault self- diagnosis function The welding machine can detect all the unnormal conditions of welding machine, such as the circuit voltage status of main engine connection automatically ( open- phase, fluctuation) , damaged part of the inner components of welding machine, and etc. , which has a great significance for protecting the welding machine and timely debugging ( the welding machine has no fuse wire) .

● Techniques in the setting function Air supply in advance, rise time of striking current, constant current control, decay time of current, arc stopping current, gas delay, base current, peak current, duty cycle and pulse frequency are adjustable. Hua’ao welding machine doesn’t set up the corresponding button on the panel to influence the visual sense of operators, and it is set in the inner module of welding machine and can be moved out to adjust just like moving out from a computer.

● Low –power and high- performance The efficiency reaches 90% and the power factor reaches 0.89, which saves energy by more than 40% than general welding machine.

2. Operation aspect

● The panel adopts the intelligent design Air supply in advance, rise time of striking current, constant current control, decay time of current, arc stopping current, gas delay, base current, peak current, duty cycle and pulse frequency can be realized by two buttons the function option and parameter option.

3. Welding performance aspect

● Most excellent welding quality The heart of welding machine is the digital microcontroller that makes centralized treatment for all welding data, gives digital control and monitoring for the whole welding process, make reaction for change of any welding process quickly, and the arcing is especially steady.

● Exact arcing function the welding machine has a method of high frequency, which makes a very high arcing success rate.

● Suitable for multiple materials Suitable for welding carbon steel, stainless steel, galvanized sheet, copper, and etc.

● Special four- step welding process The arc striking and arc suppression current can be set exactly, which reduces the welding defect of arc striking and arc suppression greatly.

Published date: December 24, 2014 -

  • 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!
