MAINTENANCE
General Instructions for Diesel Engine
Welders
1. Blow out the welder and controls with an air hose
at least once every two months. In particularly
dirty locations, this cleaning may be necessary
once a week. Use low pressure air to avoid driving
dirt into the insulation.
2. “Current Range Selector” contacts should not be
greased. To keep the contacts clean, rotate the
current control through its entire range frequently.
Good practice is to turn the handle from maximum
to minimum setting twice each morning before
starting to weld.
Auxiliary Power
The AC auxiliary power, supplied as a standard, has a
rating of 3.0 kVA of 115/230V AC (60 Hz).
With the 3.0 kVA, 115/230V AC auxiliary power, one
duplex 115V grounding type receptacle (NEMA
configuration 5-15R) is provided. For the 230V AC
power, one grounding type duplex receptacle is
provided (NEMA configuration 6-15R). The circuit is
protected with circuit breakers.
The rating of 3.0 kVA permits a maximum continuous
current of 13 amps to be drawn from the 230 volt
duplex receptacle. Or a total of 26 amps can be
drawn from the 115 volt duplex receptacle. The 115
volt duplex receptacle has a configuration which
permits 15 amps to be drawn from either half.
Therefore, on this machine, up to 15 amps continuous
can be drawn from one half and the balance of 11
amps from the other half. The total combined load of
all receptacles is not to exceed 3.0 kVA.
An optional power plug kit is available. When this kit
is specified, the customer is supplied with a plug for
each receptacle. In this case, he will receive two 15
amp, 115 volt plugs (NEMA configuration 5-15P) and
two 15 amp, 230 volt plugs (NEMA configuration
6-15P).
Have qualified personnel do the maintenance
work. Turn the engine off before working inside
the machine. In some cases, it may be
necessary to remove safety guards to perform
required maintenance. Remove guards only
when necessary and replace them when the
maintenance requiring their removal is
complete. Always use the greatest care when
working near moving parts.
Do not put your hands near the engine cooling
blower fan. If a problem cannot be corrected by
following the instructions, take the machine to
the nearest Lincoln Field Service Shop.
