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.2 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.

CONNECTIONS

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.

Always connect the OPTIMARC® grounding lug

(located at the rear of the case) to a proper safety

(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)

500A

Up To 30m Length

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.

Special instruction as follows:

For steel pulse mode, use 90%Arǃ10%CO2;

For stainless steel pulse mode, use 98%Arǃ2%CO2.

xTurn the OPTIMARC® CV machine’s power switch

“OFF”.

xConnect the control cable from the PWF wire feeder

to the 6-pin connector.

xConnect the electrode cable.

Note: GMAW or FCAW-G, electrode cable should be

connected to positive output stud;

For secure electrical connection, the screws

connecting the output terminals and cables must

be tightened. Damage may occur to the output stud

or welding performance maybe compromised.

SAFETY PRECAUTIONS

Read this entire section of operating

instructions before operating the machine.

ELECTRIC SHOCK can kill.

xDo not touch electrically live

parts or electrode with skin or

wet clothing.

xInsulate yourself from work

and ground.

xAlways wear dry insulating gloves.

FUMES AND GASES can be

dangerous.

xKeep your head out of fumes.

xUse ventilation or exhaust to

remove fumes from breathing

zone.

WELDING SPARKS can cause

fire or explosion.

xKeep flammable material

away.

xDo not weld on closed

containers.

ARC RAYS can burn eyes and

skin.

xWear eye, ear and body

protection.

PLEASE SEE ADDITIONAL WARNING

INFORMATION AT THE FRONT OF THIS

OPERATOR’S MANUAL.

DUTY CYCLE

The duty cycle of a welding machine is the percentage

of time in a 10 minute cycle at which the welder can

operate the machine at rated welding current.

60% duty cycle:

Weld for 6 minutes

Break for 4 minutes

Excessive extension of the duty cycle will cause the

thermal protection circuit to activate.

THERMAL PROTECTION

The OPTIMARC® machine is equipped with a thermal

protection device. When the machine has gone into

thermal overload, the output will be turned off and the

thermal indicator light will be turned “ON“. When the

machine has cooled to a safe temperature, the Thermal

Indicator Light will go out and the machine may resume

normal operation.

Note: For safety reasons the machine’s welding output

will not come on after a thermal shutdown until the

output is disabled and re-enabled.
