SAFETY PRECAUTIONS

Read the entire installation section before starting installation.

INPUT POWER AND GROUNDING

ELECTRIC SHOCK can kill.  Only qualified personnel

should perform this installation.

 Turn 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.

 Do not touch electrically “Hot” parts.  Always 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.

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.

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 .

WARNING

PROCESS SELECTIONS AND CONNECTIONS

ELECTRIC SHOCK can kill.  Only qualified personnel

should perform this

installation.

 Turn 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.

 Do 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

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.

Weld for 6 minutes

Break for 4 minutes

WARNING

ELECTRIC SHOCK can kill.  Do not touch electrically live

parts or electrode with skin or wet clothing.

 Insulate yourself from work

and ground.

 Always wear dry insulating gloves.

FUMES AND GASES can be dangerous.

 Keep your head out of fumes.  Use ventilation or exhaust to

remove fumes from breathing zone.

WELDING SPARKS can cause fire or explosion.

 Keep flammable material away.  Do not weld on closed

containers.

ARC RAYS can burn eyes and skin.  Wear 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:

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.

DIP SWITCH DESCRIPTIONS

OPTIMARC® CV/CC machine offers a DIP switch on the control board, which allows user to have additional

features. After disconnecting the machine from input power remove the roof To set the DIP switch。

Disconnecting the machine， before the roof removed.

See FIGURE B.7 for the right position. There are 8 individual switches integrated into this DIP switch .All the initial factory settings in the OFF position. Please see FIGURE B.6.

1. PREFLOW ON/OFF SWITCH

This switch enables preflow before turning on output voltage. Please see FIGURE B.3 for detail.

2. LONG CABLE WELD MODE SWITCH OFF = welding with a cable length less than 20M. ON = welding with a cable length more than 20M (including 20M).

3. CRATER REPEAT MODE SWITCH

Should the operator find a visible crater appearing after releasing the trigger, and within 2 seconds, activating the trigger again the power source will

crater. For more details, please see FIGURE B.5.

4. SPECIAL FUNCTION TEST

It enables a test procedure to test the control knobs and the toggle switches, when the DIP switch 4 is ON and the other DIP switches are OFF. The DIP switch should be OFF when user prepares to weld.

5. SYNERGIC

OFF = Amps and volts knobs on feeder are independent ON = Preset of volts knob is tied to the preset of the amps knob. Preset a current first , then set the voltage to match the current, as 200A, 25V, then the voltage will follow the current as machine programmed when the current adjusted. See operation feature item 8.

6. FAST RUN-IN

OFF = run-in is 35% of weld set wire feed speed (limited by the absolute wire feed speed minimum set in the parameter file) ON = run-in is 75% of weld set wire feed speed (limited by the absolute wire feed speed minimum set in the parameter file)
