Redstar Equipment presents the DLW-400ESW, a range of diesel welders designed for high performance, easy maintenance and low noise operation.

The engine is equipped with the Closed Breathing System, which keeps the blow-by gas in the machine while the aluminium radiator does not cause lead pollution, allowing the diesel welders to meet emission gas regulation stage 2, enforced by the Ministry of Land, Infrastructure and Transport.

A slowdown device in the DLW-400ESW diesel welders automatically lowers engine speed during no-load, reducing noise and increasing fuel efficiency.

The generator is equipped with an automatic air-venting unit that eliminates air by turning a switch key when restarting the engine after fuelling.

The use of brushes or slip rings in the alternator eliminates the need for maintenance. Additionally, the DLW-400ESW diesel welders are built for easy daily inspection and maintenance to be carried out on one side of the machine. The radiator can be cleaned easily by removing the front cover.

Safety features in the DLW-400ESW diesel welders:

  • Automatically cuts the power off when over-loading DC output 
  • Protects overloading AC output by shutting down its circuit breaker 
  • Automatically stops the engine with the warning indicators at low oil pressure, high water temperature and insufficient charging of the battery 
  • Prevents electric leakage with a relay 
The DLW-400ESW diesel welders incorporate a unique e·mode function designed to reduce fuel consumption and noise level. During e·mode operation (idling speed), the unit controls welding current up to 240A, reducing fuel consumption by 25-30% compared with other standard welders. 

Additionally, a newly developed hood structure incorporating a new cooling system dramatically reduces noise level.
