Welding Machines

DLW series Welding machines

The improved diesel engine welders achieve low fuel consumption and low noise in newly developed e mode operation. High quality AC power can be used while welding is being performed

All the products are provided with the following functions

Clean engine- the engine equipped with the closed breathing system which keeps the blow by gas in the machine, and the aluminum radiator which does not cause lead pollution is categorized as a construction machine that satisfies the emission gas regulation stage 3.

Slowdown device educes noises and saves

The slowdown unit automatically lowers engine speed during no-load, reducing noise and increasing fuel efficiency

Easy Daily inspection & maintenance

Daily inspection and maintenance can be carried out on one side of the machine. In addition , the radiator can be cleaned easily removing  the front cover

Switch key operation restarts with air vented automatically the engine

The machine equipped with an automatic air venting unit that eliminates air by turning switch key when restarting the engine after fueling

Alternator requires maintenance free

The use of brushes or slip ring in the alternator eliminates the need for maintenance

Various protective systems assuring safety

The machine can automatically cut the power off when overloading DC output

Protect overloading ac output by shutting down its circuit breaker

Automatically stops the engine with the warning indicators, at low lube oil pressure, high water temperature and insufficient charring of the battery

Prevent electric leak with its relay

Remote Control Devices

The engine generator can be remotely changed from low speed to high speed operation, started and stopped, and otherwise controlled. The ability to perform these procedures automatically or manually at the location where work is being performed when the engine generator is separated by a considerable distance provides high fuel and oil savings, extends engine life substantially, and leads to a surprising level of reduction in manpower and energy requirements. In addition, this also minimizes noise and exhausts gas discharge levels, and in turn helps improve the worksite environment.

Automatic Idling Device or Slowdown Device

Automatic Idling Device
（For DCA-45 to 150, provided as standard feature for DCA-220 and above）
（Cannot be used with 45ESI, 45USI2）
This device automates warm-up operation when the engine is started. The addition of a remote-control box allows remote changeover between low-speed and high-speed operation.
（Please note that the engine cannot be started and stopped with the remote-control box.）
Slowdown Device
（For DCA-45 to 150）（ cannot be used with 45ESI, 45USI2, 60ESI2 ）
In addition to a slowdown function that automatically changes to high-speed operation when a load is applied, and to low-speed operation when there is no load, this device has an automatic idling function that per forms warm-up operation when the engine is started between 5and 180 seconds depending upon the room temperature where the unit is located）. Furthermore, the addition of a remote-control box allows the engine starting/stopping and automatic idling function as well as the slowdown functions
To be operated from a remote location.

Remote Controller（ for DCA-220 to 1100）

This device allows the engine starting/stopping and automatic idling function （idling when engine is started） to be operated from a remote location. In addition to a switch for changeover between high-speed and low-speed operation, the remote-control box has a high-speed/low-speed operation indicator lamp, a start up warming lamp (comes on when
Generator set is not started up using normal remote controller operation), and a malfunction indicator lamp illuminated when the emergency stop device is triggered）.
Note: The remote-control box for the DCA-800SPM differs from the picture.

Automatic Oil Lubrication Device

（For DCA-25 to 800, provided as standard feature for DCA-500ESM, 610SPM,
800SPM and 1100SPM, 1100SPC）（Cannot be used with 25USI2,25ESK）
This system automatically maintains engine oil at the proper level, making it possible to reduce costs for oil-related maintenance, and eliminates the need to check the engine oil level.

Automatic Fuel Replenishment Device

（For DCA-25ESI, 45 to 60）
When the level in the unit tank drops after an extended period of operation, a level sensor detects this and an electric pump is operated to automatically replenish fuel in the unit tank from a separate tank. （Cannot be used with three-way valve.）

Salt Corrosion Specifications

（For DCA-13 to DCA-220, provided as standard feature for DCA-300 and above）
These specifications are designed for when the unit will be used on the coast or on the ocean, and include treatment to prevent insulation resistance from dropping, and corrosion resistant treatment of the part.

Three-Phase/Single-Phase Output
Changeover Device

（For DCA-13LSK, 13LSY, 25ESK, 25ESI, 45ESH, 45USI2, 60ESH, 60USH2）
This device facilitates easy changeover between the three-phases and single-phase output modes with the three-phase/single-phase changeover switch in the control panel. The control panel has an output mode confirmation window and indicator lamp so that the output mode can be confirmed at any time.
（DCA-45USI2 and 60USH2 only provided with indicator lamp.）

Parallel Operation Device

A variety of optional devices are available to change from manual parallel operation to the desired type of automatic operation. Select the desired option from the table below according to the power supply application, site conditions and other factors.
（1）Manual Parallel Operation Device: Parallel operation system with unique
Denyo AVR equipped with a cross-current compensation circui（t CCR system）.
This is the most inexpensive system, where no addition equipment is required for
the DCA-125 and above.
（2）Automatic Load Sharing Device: This device operates a governor motor to share the load uniformly among the respective generators when parallel operation is being per formed. It facilitates stable parallel operation, and dramatically reduces the workload of monitoring during parallel operation.
（3）Automatic Parallel Operation Device: The troublesome synchronization verification and synchronization activation process can be automatically performed by simply pressing a pushbutton. After synchronization is activated, the Automatic Load Sharing Device is capable of performing stable parallel operation.
（4）Fully Automatic Parallel Operation Device: High-speed digital control enables all operations from star ting and stopping to synchronization verification, synchronization activation and load sharing to be performed at the touch of one button. This device has multiple functions that enable parallel operation of generators with differing capacities, the number of units being operated to be controlled and other operations.

Applicable models: DCA-220ESM, 400ESM, 500ESM, 610SPM, 800SPK, provided as standard feature for DCA-800SPM.
（5）The generator may be classified as a normal use generator according to the
Electricity Enterprises Law depending upon the installation and operation procedure. Consult with a sales person for details.
Trailer
Trailers can be fitted to generators to facilitate on-site movement.
（trail-ers for DCA-60 and below are two-wheel ; those for
DCA-75SP through 400 are four-wheel）
Bolt connectors make mounting and dismounting simple.
