Product Overview

The HW1200 is a high-power four-arc welding model in the DENVO/engine welder Diesel Engine-Driven Welders series. It adopts a diesel water-cooled engine and a large-diameter electrode output design. The welding output is realized through four independent circuits. A single device can connect four welding guns at the same time to meet the stringent needs of multi-station and large-current welding of large-diameter pipelines and heavy-duty industries. The equipment has its own power generation power supply, with high-power auxiliary power output, which can drive multiple power tools and welding equipment at the same time, and is the main model for super-heavy industrial welding scenarios.

The HW1200 is designed for ultra-large-scale projects such as φ1422mm international pipelines, LNG receiving stations, offshore platforms, and large storage facilities. With its high power output, continuous operation capabilities, and automated welding support, it provides reliable mobile welding support for major energy infrastructure construction.

Detailed explanation of four-arc welding technology

• Four independent outputs: A single device can be connected to 4 welding guns at the same time, each independently controlled, greatly improving the welding output of a single device, reducing the number of devices and site layout.
• High power output: Facing large-diameter thick-walled pipes and heavy-duty industrial welding, the rated output covers the needs of large-diameter welding electrodes, and the weld depth and forming are reliable.
• Water-cooled cooling system: Long-term full-load operation can remain stable to meet the needs of continuous high-strength construction.
• Automated Welding Support: It can be used with automatic welding equipment to provide stable power for automatic pipeline welding and robot welding.
• Industrial Grade Design: Protection class IP23, insulation class H, suitable for harsh site environment, all-weather reliable operation.

FAQ

1. Can the four outputs of the HW1200 be adjusted independently?

Yes. The four welding outputs of the HW1200 are independent of each other, each of which can independently control the current. Four welders can simultaneously carry out welding operations with different process parameters without interfering with each other.

2. Which welding processes are suitable?

The HW1200 supports manual arc welding of large-diameter electrodes and automatic welding with automatic welding equipment, which is suitable for bottoming, filling and cover welding of thick plates and large-diameter pipes.

3. Is the equipment suitable for continuous operation for a long time?

Suitable. The HW1200 adopts a water-cooled heat dissipation system and a large-capacity fuel tank design with a protection grade of IP23, which can run continuously for a long time under heavy load conditions to meet the high-strength construction needs of large-scale projects.

4. Can it be used as a generator set?

The HW1200 comes with a high-power auxiliary power supply. After welding, it can provide power output for on-site lighting, power tools and other equipment. One machine is multi-purpose, reducing the input of on-site equipment.
