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.


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.


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.


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.
