three phase gasoline welding generator for construction work

The three-phase gasoline welding generator is a multifunctional device that not only provides essential power support for worksites, but also meets demanding welding requirements and ensures high welding quality. It is ideal for complex working environments such as fieldwork, construction projects, and municipal emergency repairs, offering both stable power output and reliable welding current for smooth operations where stable grid power is unavailable.

Working Principle of Three-Phase Gasoline Welding Generator

This generator adopts an OHV four-stroke gasoline engine as its power source, which drives the generator set to deliver stable three-phase power output. At the same time, it features a dedicated welding function, supplying strong and stable current for welding by adjusting the current and voltage as needed. The three-phase current system provides efficient power distribution and maintains a stable current during welding, effectively preventing voltage fluctuations from affecting welding quality.

The engine’s optimized fuel injection system ensures complete gasoline combustion for lower emissions, reduced noise, and improved fuel efficiency. The use of an all-copper wire motor further enhances output stability, extends equipment life, reduces voltage distortion, and ensures high-quality welding current.
