Denyo DLW-300ESW [3/4] Dlw 400esw

150A

120A

Constant current

characteristic mode

Even when the arc

length becomes long

and thus the voltage

rises, the current

remains same.

Non-step automatic control with a microcomputer assures

optimum engine revolutions under any load conditions, with

slow-down （low-speed） revolutions kept under no load.

The fuel cost can thus be reduced, ultra-low fuel

consumption achieved, and ultralow noise level maintained

under any working conditions.

The best arc-welding characteristics

The e-AVC300's microcomputer-aided welding control

assures quiet, optimum operation that will accommodate

any kind of welding rod.

400ESW

DLW-300LSW

DAW-180SS

Lightweight and compact design with water-cooled

2-cylinder diesel engine.

The improved diesel engine welder achieves low fuel consumption and

low noise in newly developed e-mode operations.

High-quality AC power can be used while welding is being performed.

Two persons can perform welding simultaneously in e-mode operations.

Provided with short-circuit current regulator.

DLW SERIES

DAW/TLW SERIES

Welding Mode Selector Switch

is equipped:

DENYO’s DLW series welders are

equipped with Welding Mode Selec-

tor Switch which enables the welding

workers to change the working mode

between the drooping characteristics

mode and the constant current char-

acteristic mode.

3Position control of engine

rotation (e-mode) is equipped:

(for DLW-300LS）

DLW-300LS is able to control in a

non-step fashion the number of rota-

tions in compliance with the load to

be applied and a lower noise level

and lower fuel consumption are

attained with an excellent job perfor-

mance.

e-mode

When welding work is performed steadily, the machine becomes low

speed mode. When the alternate current generator becomes in opera-

tion, the machine operates at high speed mode and the generator

becomes in an unloaded condition, the machine comes back to low

speed mode.

Four-wheel kit

remote controller

Duty Cycle 100% is realized:

Denyo’s welding machines realized duty

cycle 100% by adopting high-performance

generators and allowance-rich engines.

Worker may select the optimum

mode or e-mode from the 3

positions of control.

This realizes a lower consump-

tion of fuel.

Width560mm!

Superior Design

(for DLW-300LSW and DLW-400ESW)

Fuel gauge will indicate with red signal when

level is low, and readability have been

enhanced in other gauges and meters, such as

Hour Meter, Frequency lamp, etc.

Drooping character-

istic mode

When the arc length

becomes long and thus

the voltage rises, the

current decreases.

Variable /Low Speed Mode

When the welding work starts, the rotation of

equipped engine works under non-step and

variable rotation manner and the welding

machine works at high speed mode when it is

connected to alternate current (AC) power and

works at low speed mode when it is under no

load of current.

High/Low Speed Mode

When the welding work is performed by the

machine or the welder is connected to

alternate current (AC) power, the machine

works at high speed mode, and when the

machine is under no load of current, it works at

low speed mode.

High Speed Mode

The welder works at high speed mode regard-

less non-load conditions or loaded conditions.

Clean Engine

The engine equipped with the Closed Breathing System which

keeps the blow-by gas in the machine, and the alminum radiator

which does not cause lead pollution is categoried as a construction

machine that satisfies the emission gas regulation stage 3

and Transport （

）

Slowdown device reduces 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 one side of

the machine.

In addition, the radiater

can be cleaned

easily by removing

the front cover.

Switch key operation restarts the engine with air

vented automatically

The machine is equipped with an automatic airventing unit that

eliminates air by turning a switch key when restarting the engine

after fueling.

Alternator requires maintenace free

The use of brushes or slip rings in the alternator eliminates the need

for maintenance.

Various protective systems assuring safety

●This machine can automatically cut the power off when

over-loading DC output.（except for TLW-230LS）

●Protect over-loading AC output by shutting down its circuit

breaker.

●Automatically stop the engine with the warning indicators, at low

lub oil pressure, high water temperature, and insufficient charging

of the battery.

●Prevent from electrial leaking with its relay.

（optional for all the products）

Options:

Four-wheel kit

（except for DAW-180SS）

, exhaust pipe attach-

ment, remote controller, mesures against salt damage.

All the products listed in this brochure

are provided with the following functions.

Welding work can be performed under a

low-speed condition of the engine: (for

DLW-300LSW and DLW-400ESW)

Full Range Mode

When welding work starts or the equipped AC

generator starts to operate, the welding machine

works at high speed mode and when the unloaded condition of current is

applied, the machine operates at low speed mode.

Short-circuit current during weld-

ing work can be adjusted:

The conditions of welding work can be

freely adjusted from “Hard” to “Soft” at the

discretion of a welding worker by Arc

Force Regulator. When “Soft” is selected,

the current for welding work becomes

stable and welding of pipes and upward

welding become easier to do. On the

other hand, when “Hard” is selected, start

of arc becomes much smoother.

Voltage reducing device is equipped:

DENYO’s engine-driven welding machines

is capable to reduce the welding open

circuit voltage down to 15V for non-working

conditions and thus it is

possible to prevent electric

shocks of welding workers

even at a place of a high

altitude and a high humidity.
