HWG Hydraulic Welding Generator

DYNASET HWG Hydraulic Welding Generator converts the hydraulic power of a mobile machine into welding current and auxiliary electricity. HWG Hydraulic Welding Generators produce high quality welding current from 180 A up to 400 A. HWG 180/220/300/400 units also provide auxiliary AC-power from 6 kVA up to 10 kVA. Portable HWG models are the lightest hydraulic welders in the world weighting only 17 kg (37.4 lbs.). They produce up to 250 A welding current and provide DC electricity up to 2 kW.

Base machines and installation

The world’s best power-to-size ratio guarantees easy installation on mobile machinery such as excavators, drill rigs, service vehicles. It can be connected into any hydraulic system and thanks to its compact and light weight, it is easy to install anywhere on the mobile machine. HWG can be located in confined space since it doesn’t need to be powered by a diesel generator. How does DYNASET HWG Hydraulic Welding Generator work?

HWG Hydraulic Welding Generator produces high quality welding current using the power from the base machine’s hydraulic system. The HWG is turned on by opening the hydraulic oil flow to it. Then the hydraulic system feeds the hydraulic oil flow to the HWG’s hydraulic motor. The motor is integrated into the generator and when it starts the generator produces electricity immediately. HWG is designed to handle fluctuating hydraulic oil flows to ensure steady high quality electricity all the time.

Productivity

Having the HWG Hydraulic Welding Generator on a mobile machine increases its productivity and net worth. HWGs are compact and don’t require additional electric power source. There is no more need for dragging big separate generators to the work sites, HWG is always aboard and ready for use. No need for many several equipment you can have it all in one, welding current and auxiliary electricity.

Clean technology

DYNASET HWG Hydraulic Welding Generator is eco-friendly. As a difference from electric welders, which require diesel generator to operate, it runs with hydraulic power of the base machine. Therefore it does not require any fuel and does not generate air pollution. Thanks to DYNASET clean technology, there are less emissions and natural resources consuming equipment at worksites. HWG Hydraulic Welding Generator is maintenance-free and doesn’t require transportation since it is integrated into the base machine.

The new silent hydraulic motors integrated in the HWG Hydraulic Welding Generator (K series)

The new silent hydraulic motors, released on March 7th 2017, are integrated in the strandard models of the HWG Hydraulic Welding Generator (K series). The new hydraulic motors will improve the generators in many ways.

The most noticeable change is the drastically improved sound. The sound pressure level is significantly lower. However this is not the only factor that makes the motor sound more pleasing for the ear. The improved sound structure and frequency level are even bigger factors which make the Dynaset equipment almost feel like silent. The high pitch sounds are unpleasant for the human ear and big amplitudes tend to hurt the ears. The new Dynaset silent hydraulic motors are designed to produce sound which structure and frequency are more subtle for the ears. Therefore the motors sound very quiet. The better sound characteristics drastically improve the working environment and user ergonomics.

The silent hydraulic motors are designed to be more efficient and durable. The new Dynaset motors have less mechanical friction resulting better efficiency and increasing durability. The operating temperature is lower as well. The new shaft seal is made for higher pressure endurance. The new silent motors are easy to recognize from the all-black motors with Dynaset logo on them.

The DYNASET silent hydraulic motors bring better user experience thanks to

  • lower sound pressure level lower frequency pleasant sound structure less mechanic friction increased efficiency lower operating temperature better durability

Please notice that the portable models of HWG are made with different hydraulic motor.
