ASPECT ® 230 DC
INSTALLATION
SAFETy PRECAUTIONS
Read entire installation section
before starting installation.
WARNING
ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this installation.
• Turn the input power OFF at the
disconnect switch or fuse box before
working on this equipment.
• Do not touch electrically hot parts.
• Always connect the ASPECT
grounding screw (behind the terminal block located
near the back of the right case side) to a good electrical
earth ground.
• Always connect the ASPECT
grounded in accordance with the National Electrical
Code and all local codes.
SELECT SUITABLE LOCATION
Place the welder where clean cooling air can freely circulate in
through the rear vents and out through the front vents. Dirt, dust or
any foreign material that can be drawn into the welder should be kept
at a minimum. Failure to observe these precautions can result in
excessive operating temperatures and nuisance trips.
GRINDING
Do not direct grinding particles towards the welder. An abundance of
conductive material can cause maintenance problems.
STACKING
The Aspect ® 230 DC cannot be stacked .
UNDERCARRIAGE LIFTING AND MOVING
When the Aspect ® 230 DC is purchased as a welding package, or
used with any of the available Undercarriage optional accessories,
proper installation makes the Aspect
Do not attempt to lift the power source with an undercarriage
attached. The undercarriage is designed for hand moving only;
mechanized movement can lead to personal injury and/or damage to
the Aspect ® 230 DC.
TILTING
Each machine must be placed on a secure, level surface, either
directly or on a recommended cart. The machine may topple over if
this precaution is not followed.
ENCLOSURE RATING

MACHINE GROUNDING AND HIGH FREQUENCy
INTERFERENCE PROTECTION

Locate the Aspect 230 DC away from radio controlled machinery.

operation of RF controlled equipment, which may result in bodily
injury or damage to the equipment.
The frame of the welder must be grounded. A ground screw marked
with the symbol is located on the rear panel for this purpose. See
your local and national electrical codes for proper grounding methods.
The high frequency generator, being similar to a radio transmitter,
can be blamed for many radio, TV and electronic equipment inter-
ference problems. These problems may be the result of radiated
interference. Proper grounding methods can reduce or eliminate
radiated interference.
Radiated interference can develop in the following four ways:
• Direct interference radiated from the welder.
• Direct interference radiated from the welding leads.
• Direct interference radiated from feedback into the power lines.
• Interference from re-radiation of "pickup" by ungrounded
metallic objects.
Keeping these contributing factors in mind, installing the equipment
per the following instructions should minimize problems:
1. Keep the welder power supply lines as short as possible. Input
leads within 50 feet (15.2 m) of the welder should be enclosed in
rigid metallic conduit or equivalent shielding. There must be
good electrical contact between this conduit and the welder.
Both ends of the conduit must be connected to a driven ground
and the entire length must be continuous.
2. Keep the work and electrode leads as short as possible and as
close together as possible. Lengths should not exceed 25 feet
(7.6 m).
3. Be sure the torch and work cable rubber coverings are free of
cuts and cracks that allow high frequency leakage. Cables with
high natural rubber content, such as Lincoln Stable-Arc
resist high frequency leakage than neoprene and other synthetic
rubber insulated cables.
4. Keep the torch in good repair and all connections tight to reduce
high frequency leakage.
5. The work piece must be connected to an earth ground close to
the work clamp, using one of the following methods:
• A metal underground water pipe in direct contact with the earth
for ten feet or more.
• A 3/4" (19 mm) galvanized pipe or a 5/8" (16 mm) solid
galvanized iron, steel or copper rod driven at least eight feet
into the ground.
The ground should be securely made and the grounding cable should
be as short as possible using cable of the same size as the work
cable, or larger. Grounding to the building frame electrical conduit or
a long pipe system can result in re-radiation, effectively making these
members radiating antennas. (This is not recommended).
6. Keep all access panels and covers securely in place.
7. All electrical conductors within 50 feet (15.2 m) of the welder
should be enclosed in grounded rigid metallic conduit or
