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
