New electric welding machines are shipped in batches! Professional welding equipment covering all kinds of scenarios

[Latest news from Chongqing Lianwai Technology] A full range of new generator welding machines are officially launched on the market, and are available for direct shipment worldwide

In June 2025, Chongqing Lianwai Technology Co., Ltd. announced that its new generation of welding machines has completed mass production and will start shipping to global customers from now on. The new products include core categories such as Portable Welding Generator , Diesel Engine Driven Welders , and Oil & Gas Pipeline Welding Machines , and simultaneously support MMA/TIG/ FCAW (manual welding/argon arc welding/ flux core welding ) and other welding process scenarios to meet professional needs in the fields of construction , industry, mining, energy, etc.

New product highlights: technical upgrades for full-scenario adaptation

Multi-fuel power matrix

• • Petrol-Powered : Models such as SUA200A and WDF-250 are equipped with high-efficiency gasoline engines, supporting 120A-250A welding currents, suitable for mobile scenarios such as outdoor emergency repairs and civil maintenance, and come standard with an AC 5.5kW auxiliary power supply that can simultaneously power lighting and tools.
  • Diesel-Powered : The WD600 and LWG8000iE series use low-fuel-consumption diesel engines with a maximum output of 600A current, meeting the heavy-load requirements of oil and gas pipelines (Oil & Gas Welding), steel structure welding, etc., with a load continuity rate of 100% .
  • Gas/silent design : New 7kW silent gasoline generator (GENWELD LWG-5000i) and 4L intelligent variable frequency generator, with noise less than 70 dB, suitable for environmentally friendly scenarios such as urban construction and indoor operations.
•  

Industrial-grade process coverage

• • Special for pipeline welding : H400 and WD400-Ⅱ double-handle welding machines support professional processes such as cellulose welding and downward welding. They have passed the oil pipeline engineering certification and are suitable for high-pressure pipeline docking and oil and gas field construction.
  • Full arc welding solution : LWG600 series integrates MMA/TIG/ FCAW/ Gouging (manual welding/argon arc welding/ flux core welding/ carbon arc gouging) functions, can weld 1.6-10 mm electrodes , is compatible with stainless steel, carbon steel and other materials, and meets the industrial needs of ships, pressure vessels, etc.
•  

Balance between portability and efficiency

• • Lightweight models such as SUA130A (120A) weigh only 25kg, suitable for single-person handling and suitable for municipal maintenance and agricultural machinery repair (Agriculture Welding);
  • Large equipment such as the 800A oil and gas pipeline welder is equipped with a 40kW auxiliary power supply, which can drive the welding equipment and lighting system at the same time, improving field construction efficiency.

Why choose Lianwai Technology's new products?

• Certification and quality : All products have passed CE and ISO9001 certification. The diesel engine model is equipped with a turbocharged water cooling system, which improves the continuous operation stability by 30% and is suitable for extreme environments of -20℃ to 50℃.
• Stock and Service : Directly shipped from Chongqing factory, supports global sea/air transportation, provides 2-year warranty and remote technical support, and launches customized voltage (220V/120V) models for Southeast Asia, the Middle East and other regions.
• Industry adaptation cases :
  • The Philippines construction project purchased 200 portable welder generators for infrastructure repairs;
  • The Middle East oil and gas field ordered WD600 series welding machines to meet the needs of pipe welding in desert environments.
