The HW320DS is a silent diesel power generation welding all-in-one machine, which uses the Kubota D905 three-cylinder water-cooled diesel engine imported from Japan, with a rated output power of 14.2kW. The welding machine adopts TLQ two-stage four-pole brushless power generation welding technology and is equipped with a unique DCCs digital computer control system. It provides 45-300A welding current adjustment and supports double-handle simultaneous welding. It is suitable for long-distance pipelines, municipal pipe networks, oil field operations and other field construction scenarios.

Application Scenarios
Long-distance pipeline welding
Suitable for field pipeline welding of DN200 ~ DN600 pipe diameters, a single device can complete 8-12 welds per day, the efficiency of double welding mode is increased by 80%, and the comprehensive construction cost is reduced by 35%. It has been successfully applied to national key projects such as the West-East Gas Transmission and the China-Russia East Line.
Municipal pipe network construction
The silent design meets the environmental protection requirements of urban construction. The three-phase power generation output can drive power tools such as cutting machines and angle grinders, and one machine can be used for multiple purposes to reduce equipment input. It is suitable for the construction of municipal works such as tap water pipeline networks, gas pipelines, and thermal pipelines.
Oilfield Maintenance Operations
Plateau adaptive design, no power attenuation at an altitude of 4500m, has been put into use in many oil fields of PetroChina and Sinopec, and is used for oil well pipeline maintenance, gathering pipeline rush repair, water injection pipeline construction and other operations.
