General Information - MULTIQUIP DLW400ESA4 Operation Manuals

When used in single mode applications, Multiquip's Model
DLW400ESA4 Whisper Weld™ is a 400 amp DC welder.
Dual mode applications provide 200 amps at each of the
A and B welding terminals.
This unit incorporates a brushless revolving field
simultaneous power generator, featuring stable arc
characteristics, excellent vibration resistance and durability.
The unit also incorporates an AC power source (14 kW)
which provides power for tools, submersible water pumps
and other industrial and construction machinery.
In addition, this unit features incredibly quiet operation
and can be operated at night or in restricted noise level
locations.
This instruction manual provides information necessary
for proper handling and operation of the welder/generator.
Please read the manual to ensure maximum operation and
long service life.

This welder-generator is powered by a 4 cylinder, 4-cycle
liquid-cooled Kubota D902E4B diesel engine. This engine
is designed to meet every performance requirement for
the generator. Reference Table 4 for engine specifications.
In keeping with MQ Power's policy of constantly improving
its products, the specifications quoted herein are subject
to change without prior notice.
EXTENSION CABLES
When electric power is to be provided to various tools or
loads at some distance from the generator, extension cords
are normally used. Cables should be sized to allow for
distance in length and amperage so that the voltage drop
between the generator and point of use (load) is held to
a minimum. Use the cable selection chart (Table 9) as a
guide for selecting proper extension cable size.
