Product Overview

The HW380 is the high-power flagship model in the Denvo/engine welder Gasoline Engine-Driven Welders series. It is equipped with an American Kohler engine and has a rated welding current of 380a. It is the model with higher output power in the gasoline welder series and is suitable for large-diameter pipe welding. The equipment is driven by unleaded gasoline, air-cooled for heat dissipation, and one-button operation for electric start-up. The weight of the whole machine is about 185kg, and the field welding operation can be completed without external power supply. It is an efficient choice for construction and emergency repair of urban gas and water supply trunk lines.

Equipped with a 3kW auxiliary power supply and a 22L large-capacity fuel tank, the HW380 can drive multiple power tools at the same time as welding, and reduce the frequency of refueling in field operations, taking into account the power performance and field convenience. It is suitable for welding tasks such as φ159-φ426mm large diameter pipelines and medium to large steel box beams.

FAQ

1. What fuel does HW380 use?

The HW380 uses standard unleaded gasoline as fuel, convenient for refueling in the field, no special fuel required, and can work continuously for a long time with a large 22L fuel tank.

2. Can I use power tools while welding?

Yes. The HW380 is equipped with a 3kW auxiliary power supply. After welding, it can supply power to equipment such as angle grinders, lighting, and small power tools. One machine can be used for multiple purposes to improve site operation efficiency.

3. Suitable for how thick electrodes?

The HW380 is suitable for φ2.0-φ7.0mm welding electrodes with a current adjustment range of 60-380A, covering most of the manual arc welding requirements from thin plates to thick-walled pipes.

4. What are the advantages over small gasoline welders?

The HW380 delivers up to 380A — compared with HW310 and other medium models, it is better suited to large-diameter pipes and thick plates — the heavy-duty choice of the gasoline series.
