Product Overview

The HW800DS is a high-power dual-handle model in the Denvo/engine welder Diesel Engine-Driven Welders series. It is equipped with a Deutz TD226B-3D original diesel engine. It uses water-cooled heat dissipation and H-class insulation design. The rated welding current is 380a × 2. The double-handle double-arc welding technology allows two welders to work independently at the same time. The equipment has a fuel tank capacity of 79L and a weight of 1200kg. It is specially designed for heavy-duty continuous operation scenarios and can operate stably for a long time.

The HW800DS is designed for high-demand projects such as φ1000-φ1422mm ultra-large-diameter oil and gas pipelines, offshore oil and gas pipelines, petrochemical combined units and ultra-high-voltage substations. With its high current output, dual-handle synergy and reliable industrial-grade design, it provides high-power welding protection for major energy and power projects.

Core Features Explained in Detail

Deutz original engine: TD226B-3D four-stroke three-cylinder engine with abundant power and smooth operation, meeting heavy-duty industrial use standards.
Dual-torch dual-arc welding: Rated output 350a × 2, two welding guns are welded at the same time and do not interfere with each other, doubling the efficiency.
High and low current switching: The current gear can be switched without stopping, adapting to the rapid changeover of different welding tasks.
Fully instrumented and alarmed: Oil volume display, ammeter, voltmeter, timer, etc., automatic alarm for abnormal oil, water temperature, battery, and oil volume.
Industrial-grade protection: IP23 protection class, H class insulation, suitable for harsh construction site environment, all-weather reliable operation.

FAQ

1. Can the output of the HW800DS be merged?

HW800DS dual-station independent output, rated 350a × 2, can support two welders to weld at the same time. If you need a single high-current operation, you can combine high and low-grade current selection switches for flexible configuration. The specific output method can be consulted with the engineer.

2. How to switch the high current gear?

A high/low current gear switch lets you change gears without stopping — quickly matching different electrode sizes and welding positions with fewer interruptions.

3. How does the equipment ensure heat dissipation when reloading for a long time?

The HW800DS adopts a water-cooled heat dissipation system, with a 79L high-capacity fuel tank and an industrial-grade structure design of 1200kg, which can meet the needs of heavy-duty continuous operation and maintain a stable output for long-term full-load operation.

4. What safety protections are included?

The equipment is equipped with an alarm function for abnormal oil, water temperature, battery, and oil volume, and is equipped with a complete instrument display to help operators grasp the status of the equipment in a timely manner and ensure operation safety.
