SAFETY PRECAUTIONS
Read the entire installation section before starting
installation.
ELECTRIC SHOCK can kill.
xOnly qualified personnel
should perform this
installation.
xTurn the input power OFF at
the main switch or fuse box
before working on this equipment. Turn off the
input power to any other equipment connected to
the welding system at the main switch or fuse
box before working on the equipment.
xDo not touch electrically “Hot”parts.
xAlways connect the OPTIMARC®grounding lug
(located at the rear of the case) to a proper safety
(Earth) ground.
SELECT SUITABLE LOCATION
This power source should not be subjected to falling
water, nor should any parts of it be submerged in water.
Doing so may cause improper operation as well as
pose a safety hazard. The best practice is to keep the
machine in a dry, sheltered area.
The bottom of machine must always be placed on a
firm, secure, level surface. There is a danger of the
machine toppling over if this precaution is not
taken.
Place the welder where clean cooling air can freely
circulate in through the back louvers and out through
the case sides. Water,dirt, dust or any foreign material
that can be drawn into the welder should be kept to a
minimum. Failure to observe these precautions can
result in excessive operating temperatures and
nuisance shutdowns.
Locate the OPTIMARC®machine away from radio
controlled machinery. Normal operation of the welder
may adversely affect the operation of RF controlled
equipment, which may result in bodily injury or damage
to the equipment.
STACKING
The OPTIMARC®machine can not be stacked. Be
sure to locate the machines on a firm level surface.
LIFTING
The OPTIMARC®machine can be moved using the
handles .
INPUT POWER AND GROUNDING
CONNECTION
Only a qualified electrician should connect the
input leads to the OPTIMARC®. Connections
should be made in accordance with the connection
diagram. Failure to do so may result in bodily injury
or death.
Open the input box on the rear of the case. Use a
three-phase supply line, the three live wires should go
through the three holes of the input wire holder and be
securely clamped and fixed. Connect L1, L2, L3 and
ground according to the Input Supply Connection
Diagram decal, refer to Figure A.1 on this page.
Make sure the amount of power available from the input
connection is adequate for normal operation of the
machine. Refer to the Technical Specifications at the
beginning of this Installation section for recommended
fuse and wire sizes.

(Earth) ground.
WORK CONNECTION
Connect a work lead of sufficient size between the
proper output stud on the power source and the work.
Be sure the connection to the work makes tight metal to
metal electrical contact. Poor work lead connections
can result in poor welding performance.
To avoid interference problems with other equipment
and to achieve the best possible operation, route all
cables directly to the work and wire feeder. Avoid
excessive lengths and do not coil excess cable.
Cable sizes are increased for greater lengths primarily
for the purpose of minimizing cable drop.
Minimum work and electrode cable sizes are as follows:
TABLE A.1
Current (60% Duty Cycle)
Minimum Copper
Work Cable Size
200A
300A
400A
500A
Up To 30m Length

50 mm2
70 mm2
95 mm

Note: The recommended cable size may need to
change depending on its quality. When the rated
current flow goes through, the total voltage drop on
ground cable and electrode cable must not exceed 4
volts.
