Product Description
400A Pipeline Engine Driven Welder Generator With Two Wheel Trailer
H400 400A Oil/Gas Pipeline & Steel Structure Single Welding Generator
Product Introduction
The H400 is a classic oil and gas pipeline welding generator widely used in China railway, CNPC, SINOPEC, and field welding construction without power. This unit outputs 400A welding current and supports multiple welding functions including MMA (Cellulose), TIG, FCAW, and Gouging. Additionally, it provides auxiliary power: AC three-phase 16kW/400V and single phase 6.9kW/230V. The H400 can be equipped with various renowned diesel engines (Kubota, Perkins, Weichai, etc.) offering strong power, stable operation, low noise, and low fuel consumption. When fitted with a trailer, it enables easy movement and self-generation, making it ideal for welding in locations without power supply and field construction operations.
Key Features
- Outputs 50/60Hz single/three-phase power simultaneously during welding process
- Equipped with renowned diesel engines for strong power, stable operation, low noise and fuel consumption
- Integrated with MMA, Cellulose, TIG, Gouging, FCAW and other welding processes for wide application
- Wide current regulating range capable of carbon arc gouging with 8mm (or above) carbon rod
- Simultaneously weld, grind, light, or run other powered tools on work-site
- Welding current/voltage parameter preset function for easy regulation
- Fast dynamic response and excellent welding performance
- Separate meters for water temperature, oil pressure and fuel volume for easy monitoring
- One-side integrated maintenance design for easy servicing
- Engine alarm functions for low oil pressure, high water temperature, low oil; generator/welder has low-voltage protection
- Forklift holes and lifting rings for easy transfer and handling
Applications
- Power tower construction
- Water pipe network construction
- Highway and railway isolation network installation
- Emergency welding and repair operations for ocean-going ships
- Construction and emergency repair of offshore oil drilling platforms
