Product Advantages
Diesel Engine Built for Long Life
The WI series uses forged steel crankshaft with lifetime warranty (broken crankshaft qualifies for free machine replacement). High-strength housing with 12.9 grade bolts, NSK or BANDUN main bearings, and WEIFU fuel system ensure reliable operation. The engine undergoes independent fuel injection angle and compression ratio tuning with recorded test data for each unit. Compared to same-power petrol generators, diesel construction provides approximately three times longer service life.
Stable Welding with Inverter DC Module
The built-in inverter DC welder delivers smooth arc performance and stable welding current from 120A to 400A, supporting electrodes up to 10mm. The inverter technology improves welding controllability and reduces current ripple compared to traditional generator welders, making it suitable for site repairs, structural welding, and general fabrication work.
Efficient Power Generation with Strong Motor Starting
Self-excited brushed alternator with AVR provides stable voltage output and handles high starting currents for inductive loads like motors, compressors, and pumps. The alternator uses cold-rolled silicon steel sheets, oil-painted reinforced winding, and extended carbon brushes (1.4 times standard life). Direct coupling between engine and alternator minimizes power loss.
Protection Features for Tough Conditions
Low oil alarm automatically shuts down the engine and lights a red LED indicator when oil level is too low. Optional HJ501/502 intelligent control system allows users to set safety ranges for frequency, voltage, and engine speed, with auto-stop on out-of-range conditions. The welding module has its own circuit breaker, which can be turned off to prevent accidental operation.
Open Frame Benefits
The open-frame design allows maximum airflow for engine and alternator cooling, making it suitable for prolonged high-load operation in hot environments. Easy access to all service points simplifies maintenance and reduces downtime for our customer.
