Weichai Power 400-500A diesel generator-electric welding machine，In the field of industrial power generation and welding equipment, the 400-500A diesel-powered integrated generator and welder serves as an efficient solution that caters to both power supply and welding needs. Below is a comprehensive summary of key parameters and features:

I. Core Configuration and Technical Parameters

Power generation system

Rated power: 10-20 kW (for power generation), with standby power reaching 12-20 kW for some models

Voltage/Frequency: 220/380V, 50Hz (compatible with single and three-phase output)

Fuel tank capacity: 50-60L, supporting 8-12 hours of continuous operation

Welding performance

Current adjustment: Wide adjustment range of 0-500A, compatible with welding rods of 2.0-8.0mm

Arc characteristics: No-load voltage 65-70V, industrial-grade inverter DC welder, 100% duty cycle

Multi-function welding: supports manual welding, TIG welding, MIG/MAG welding, and cellulose welding electrodes

"Power and structure"

Engine model: Weichai 4100D four-cylinder water-cooled diesel engine (30.1 kW) or equivalent

Fuel consumption: 206-225g/kW·h, optimized fuel efficiency

Protection design: IP21 protection level, silent model with noise level ≤75dB (at a distance of 7 meters)

Mobility: Trailer-type design (dimensions approximately 2×1.65×2m), with a net weight ranging from 950 to 1400kg

II. Functional Advantages

Dual-station operation: Some models support simultaneous operation by two welders (such as the 500A model), enhancing construction efficiency

Intelligent control: digital current regulation, automatic arc stabilization technology, reliable arc initiation in low voltage environments

Safety protection: built-in leakage protection, oil pressure/temperature/overspeed triple engine protection

III. Typical application scenarios

Field engineering: oilfield pipeline laying, municipal emergency repair, construction in areas without power grid

Heavy manufacturing: ship repair, steel structure welding, pressure vessel manufacturing

Note: Weichai diesel engines (such as the 4100D model) serve as the core power source for some integrated machines, but the overall machine brand is "Dazedong"
