Denyo Welder Icon
Engine-Driven Welders

Denyo produces more than 50 different models of engine-driven welders in ranges spanning 30A to 500A.

Its product line includes soundproof units that surpass global standards for noise control, and many which have features unique to Denyo welders, such as extremely stable auxiliary AC power source, and idle control systems that cut oil and fuel consumption by automatically reducing engine speed under no-load conditions.

Denyo also produces a multipurpose welder which can be used for manual welding, TIG/MIG welding, Gouging, and a DC dual welder for two operators simultaneously, supplying AC power.

Denyo Welder is High Performance

High performance, Eco-friendly

Easy Maintenance

Easy Maintenance with easy access door and drainage for flowing of fuel , oil and radiator.

Superior Designed Welder

Superior Design

Compact structural with improvised engine design. In newly developed “e” mode operation, it achieves low fuel consumption and noise level that promote environmental friendly. High quality AC power can be used with welding works simultaneously.

Denyo Welder is Low Noise Level

Reduce Fuel Consumption / Noise Level

With E-mode operation (idling speed), the unit controls welding current up to 300A on DLW 300ES/DLW 300ESW and 400A on DLW 400ESW respectively, reducing fuel consumption by 25 % ~ 30% compare with other standard welders. In additional, newly developed hood structure incorporations new cooling system reduce noise level.
