The H300 is a professional-grade portable welding generator specifically designed for oil and gas pipeline applications, featuring robust construction and reliable performance in field operations.
Product Overview
The H300 portable oil and gas pipeline welding generator is widely used in railway construction, CNPC, SINOPEC projects, and field welding operations where power supply is unavailable. This unit delivers 300A welding current and provides DC 3kW 220V auxiliary power. Its compact size, lightweight design, and self-generation capability make it ideal for remote locations and field construction operations.
Key Features
Advanced Welding Performance: Utilizes rotating magnetic field technology with excitation current adjustment for high efficiency, precise control, smooth current output, excellent dynamic characteristics, and fast response times.
Enhanced Reliability: Innovative coaxial structure eliminates intermediate power transmission links, resulting in simple construction, reliable performance, and minimal failure rates.
Premium Engine: Powered by Honda GX630 engine with integrated oil protection system and decompression starting mechanism to prevent engine damage from oil deficiency and ensure easy starting in low-temperature conditions.
Versatile Auxiliary Power: DC 220V/3KW output power supports operation of various site tools including lighting, grinding equipment, and other powered devices.
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 maintenance of offshore oil drilling platforms
