Product Description
500A Single Welding Generator With Two-wheel Trailer for Oil, Gas & Water Pipeline Applications
H500 500A Pipeline Welding Machine
The H500 is a professional-grade oil and gas pipeline welding generator designed for field operations without power access. This versatile machine delivers 500A welding current and supports multiple welding processes including MMA (Cellulose), TIG, FCAW, and Gouging. Equipped with powerful auxiliary power output, it can simultaneously run electric tools on site.
Compatible with renowned diesel engines including Kubota, Perkins, and Weichai for reliable power, stable operation, low noise, and fuel efficiency. Available with trailer configuration for easy mobility and self-generation capabilities.
Key Features
  • Advanced Welding Performance: Rotating magnetic field generation with excitation current adjustment for high efficiency, precise control, smooth current output, and fast response
  • Enhanced Reliability: Innovative coaxial structure eliminates intermediate power transmission links for simple design and reduced failure rates
  • Powerful Auxiliary Output: 500A welding current with AC tri-phase 25kW/400V and single phase 6.9kW/230V auxiliary power
Applications
  • Power tower construction projects
  • Water pipe network installation and maintenance
  • Highway and railway isolation network installation
  • Emergency welding and repair operations for ocean-going vessels
  • Construction and emergency repair of offshore oil drilling platforms
