HWG Hydraulic Welding Generator

DYNASET HWG Hydraulic Welding Generator converts the hydraulic power of a mobile machine, vehicle or vessel into welding current and auxiliary electricity. 

The HWG Hydraulic Welding Generator is a compact, hydraulically powered solution designed to deliver high-quality welding current for applications like pipe welding, drill shaft welding, road and infrastructure maintenance, and repair welding. With single-phase and 3-phase outlets, it also powers AC appliances, making it a versatile, always-ready power source that eliminates the need for a big separate diesel generator.

How Does the Hydraulic Welding Generator Work?

A hydraulic welding generator uses the hydraulic system of a machine, vehicle, or vessel as its power source. 

  1. Hydraulic oil flow is directed to the hydraulic welding generator’s integrated hydraulic motor via the pressure line.
  2. The hydraulic welding generator converts the hydraulic oil flow and pressure into welding current and auxiliary electricity.
  3. The hydraulic oil is then returned to the carrier machine’s hydraulic oil tank through the return line.
