SECTION 1 – SAFETY PRECAUTIONS – READ BEFORE USING

rom _nd_10/02

 Warning: Protect yourself and others from injury — read and follow these precautions.

1-1. Symbol Usage

Means Warning! Watch Out! There are possible hazards with this procedure! The possible hazards are shown in the adjoining symbols.

 Marks a special safety message.

 Means “Note”; not safety related.

1-2. Arc Welding Hazards

 The symbols shown below are used throughout this manual to

call attention to and identify possible hazards. When you see the symbol, watch out, and follow the related instructions to avoid the hazard. The safety information given below is only a summary of the more complete safety information found in the Safety Standards listed in Section 1-6. Read and follow all Safety Standards.

 Only qualified persons should install, operate, maintain, and

repair this unit.

 During operation, keep everybody, especially children, away.

ELECTRIC SHOCK can kill.

Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live whenever the output is on. The input

power circuit and machine internal circuits are also live when power is on. In semiautomatic or automatic wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is a hazard.

 Do not touch live electrical parts.  Wear dry, hole-free insulating gloves and body protection.  Insulate yourself from work and ground using dry insulating mats

or covers big enough to prevent any physical contact with the work or ground.

 Do not use AC output in damp areas, if movement is confined, or if

there is a danger of falling.

 Use AC output ONLY if required for the welding process.  If AC output is required, use remote output control if present

on unit.

 Additional safety precautions are required when any of the follow-

ing electrically hazardous conditions are present: in damp locations or while wearing wet clothing; on metal structures such as floors, gratings, or scaffolds; when in cramped positions such as sitting, kneeling, or lying; or when there is a high risk of unavoidable or accidental contact with the workpiece or ground. For these conditions, use the following equipment in order presented: 1) a semiautomatic DC constant voltage (wire) welder, 2) a DC manual (stick) welder, or 3) an AC welder with reduced open-circuit voltage. In most situations, use of a DC, constant voltage wire welder is recommended. And, do not work alone!

 Disconnect input power or stop engine before installing or

servicing this equipment. Lockout/tagout input power according to OSHA 29 CFR 1910.147 (see Safety Standards).

 Properly install and ground this equipment according to its

Owner’s Manual and national, state, and local codes.

 Always verify the supply ground — check and be sure that input

power cord ground wire is properly connected to ground terminal in disconnect box or that cord plug is connected to a properly grounded receptacle outlet.

This group of symbols means Warning! Watch Out! possible ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult symbols and related instructions below for necessary actions to avoid the hazards.

 When making input connections, attach proper grounding conduc-

tor first – double-check connections.

 Frequently inspect input power cord for damage or bare wiring —

replace cord immediately if damaged — bare wiring can kill.

 Turn off all equipment when not in use.  Do not use worn, damaged, undersized, or poorly spliced cables.  Do not drape cables over your body.  If earth grounding of the workpiece is required, ground it directly

with a separate cable.

 Do not touch electrode if you are in contact with the work, ground,

or another electrode from a different machine.

 Use only well-maintained equipment. Repair or replace damaged

parts at once. Maintain unit according to manual.

 Wear a safety harness if working above floor level.  Keep all panels and covers securely in place.  Clamp work cable with good metal-to-metal contact to workpiece

or worktable as near the weld as practical.

 Insulate work clamp when not connected to workpiece to prevent

contact with any metal object.

 Do not connect more than one electrode or work cable to any

single weld output terminal.

SIGNIFICANT DC VOLTAGE exists in inverters after stopping engine.

 Stop engine on inverter and discharge input capacitors according

to instructions in Maintenance Section before touching any parts.

FUMES AND GASES can be hazardous.

Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.

 Keep your head out of the fumes. Do not breathe the fumes.  If inside, ventilate the area and/or use exhaust at the arc to remove

welding fumes and gases.

 If ventilation is poor, use an approved air-supplied respirator.  Read the Material Safety Data Sheets (MSDSs) and the

manufacturer’s instructions for metals, consumables, coatings, cleaners, and degreasers.

 Work in a confined space only if it is well ventilated, or while

wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and lower th e oxygen level causing injury or death. Be sure the breathing air is safe.

 Do not weld in locations near degreasing, cleaning, or spraying op-

erations. The heat and rays of the arc can react with vapors to form highly toxic and irritating gases.

 Do not weld on coated metals, such as galvanized, lead, or

cadmium plated steel, unless the coating is removed from the weld area, the area is well ventilated, and if necessary, while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded.

OM-494 Page 1

Page 6

BUILDUP OF GAS can injure or kill.

FLYING METAL can injure eyes.

 Shut off shielding gas supply when not in use.  Always ventilate confined spaces or use

approved air-supplied respirator.

ARC RAYS can burn eyes and skin.

Arc rays from the welding process produce intense

visible and invisible (ultraviolet and infrared) rays

that can burn eyes and skin. Sparks fly off from

the weld.  Wear a welding helmet fitted with a proper shade of filter to protect

your face and eyes from arc rays and sparks when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards).

 Wear approved safety glasses with side shields under your

helmet.

 Use protective screens or barriers to protect others from flash and

glare; warn others not to watch the arc.

 Wear protective clothing made from durable, flame-resistant mate-

rial (wool and leather) and foot protection.

WELDING can cause fire or explosion.

Welding on closed containers, such as tanks,

drums, or pipes, can cause them to blow up. Sparks

can fly off from the welding arc. The flying sparks, hot

workpiece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before doing any welding.

 Protect yourself and others from flying sparks and hot metal.  Do not weld where flying sparks can strike flammable material.  Remove all flammables within 35 ft (10.7 m) of the welding arc. If

this is not possible, tightly cover them with approved covers.

 Be alert that welding sparks and hot materials from welding can

easily go through small cracks and openings to adjacent areas.

 Watch for fire, and keep a fire extinguisher nearby.  Be aware that welding on a ceiling, floor, bulkhead, or partition can

cause fire on the hidden side.

 Do not weld on closed containers such as tanks, drums, or pipes,

unless they are properly prepared according to AWS F4.1 (see Safety Standards).

 Connect work cable to the work as close to the welding area as

practical to prevent welding current from traveling long, possibly unknown paths and causing electric shock and fire hazards.

 Do not use welder to thaw frozen pipes.  Remove stick electrode from holder or cut off welding wire at

contact tip when not in use.

 Wear oil-free protective garments such as leather gloves, heavy

shirt, cuffless trousers, high shoes, and a cap.

 Remove any combustibles, such as a butane lighter or matches,

from your person before doing any welding.

 Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B

for hot work and have a fire watcher and extinguisher nearby.

 Welding, chipping, wire brushing, and grinding

cause sparks and flying metal. As welds cool, they can throw off slag.

 Wear approved safety glasses with side

shields even under your welding helmet.

HOT PARTS can cause severe burns.

 Allow cooling period before maintaining.  Wear protective gloves and clothing when

working on a hot engine.

 Do not touch hot engine parts or just-welded

parts bare-handed.

NOISE can damage hearing.

Noise from some processes or equipment can damage hearing.

 Wear approved ear protection if noise level

is high.

MAGNETIC FIELDS can affect pacemakers.

 Pacemaker wearers keep away.  Wearers should consult their doctor before

going near arc welding, gouging, or spot welding operations.

CYLINDERS can explode if damaged.

Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylinders are normally part of the welding process, be sure to treat them carefully .

 Protect compressed gas cylinders from excessive heat, mechani-

cal shocks, slag, open flames, sparks, and arcs.

 Install cylinders in an upright position by securing to a stationary

support or cylinder rack to prevent falling or tipping.

 Keep cylinders away from any welding or other electrical circuits.  Never drape a welding torch over a gas cylinder.  Never allow a welding electrode to touch any cylinder.  Never weld on a pressurized cylinder — explosion will result.  Use only correct shielding gas cylinders, regulators, hoses, and fit-

tings designed for the specific application; maintain them and associated parts in good condition.

 Turn face away from valve outlet when opening cylinder valve.  Keep protective cap in place over valve except when cylinder is in

use or connected for use.

 Read and follow instructions on compressed gas cylinders,

associated equipment, and CGA publication P-1 listed in Safety Standards.

1-3. Engine Hazards

BATTERY EXPLOSION can BLIND.

 Always wear a face shield, rubber gloves, and

protective clothing when working on a battery.

 Stop engine before disconnecting or connect-

ing battery cables or servicing battery.

 Do not allow tools to cause sparks when working on a battery.  Do not use welder to charge batteries or jump start vehicles.  Observe correct polarity (+ and –) on batteries.  Disconnect negative (–) cable first and connect it last.

OM-494 Page 2

FUEL can cause fire or explosion.

 Stop engine and let it cool of f before checking or

adding fuel.

 Do not add fuel while smoking or if unit is near

any sparks or open flames.

 Do not overfill tank — allow room for fuel to expand.  Do not spill fuel. If fuel is spilled, clean up before starting engine.  Dispose of rags in a fireproof container.  Always keep nozzle in contact with tank when fueling.

Considerations About Welding And The Effects Of Low Frequency Electric And Ma g netic Fields

Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such fields. However, after examining more than 500 studies spanning 17 years of research, a special blue ribbon committee of the National Research Council concluded that: “The body of evidence, in the committee’s judgment, has not demonstrated that exposure to powerfrequency electric and magnetic fields is a human-health hazard.” However, studies are still going forth and evidence continues to be examined. Until the final conclusions of the research are reached, you may wish to minimize your exposure to electromagnetic fields when welding or cutting.

1-7. Information sur les champs électromagnétiques

Données sur le soudage électrique et les effets des champs magnétiques basse fréquence sur l’organisme En parcourant les câbles de soudage, le courant crée des champs électromagnétiques. Les effets potentiels de tels champs restent préoccupants. Cependant, après avoir examiné plus de 500 études qui ont été faites pendant une période de recherche de 17 ans, un comité de spécialistes du National Research Council a conclu : « L’accumulation de preuves n’a pas démontré que l’exposition aux champs magnétiques et aux champs électriques à haute fréquence constitue un risque pour la santé humaine ». Toutefois, les études et l’examen des preuves se poursuivent. En attendant les conclusions finales de la recherche, il serait souhaitable de réduire l’exposition aux champs électromagnétiques pendant le soudage ou le coupage.

OM-494 Page 8

Afin de réduire les champs électromagnétiques en milieu de travail, respecter les consignes suivantes :

1. Garder les câbles ensemble en les torsadant ou en les fixant avec du

ruban adhésif.

2. Mettre tous les câbles du côté opposé à l’opérateur.

3. Ne pas s’enrouler les câbles autour du corps.

4. Garder le poste de soudage et les câbles le plus loin possible de soi.

5. Placer la pince de masse le plus près possible de la zone de soudage.

Consignes relatives aux stimulateurs cardiaques :

Les personnes qui portent un stimulateur cardiaque doivent avant tout consulter leur médecin. Si ce dernier les déclare aptes, il leur est recommandé de respecter les consignes ci-dessus.

Duty Cycle is percentage of 10 mi n utes that unit can weld at rated load without overheating.

 Exceeding duty cycle can

damage unit and void warranty.

If a weld module overheats, the High Temperature light goes on and the thermostat opens to stop weld output to that module. Wait fifteen minutes for module to cool. Reduce amperage, voltage, or duty cycle before welding.

This unit has separate duty cycle ratings for each operating mode. If the unit is operated in the dual operator mode, the unit is rated at 40% duty cycle. This means each side of the unit can be operated at 275 amperes at 40% duty cycle.

When the unit is operated in the single operator mode, the Welder B side (right) is rated at 40% duty cycle (550 A at 40% duty cycle).

5-3. Weld Control Descriptions (See Section 5-2)

1 Welder Selector Switch Use switch to select Dual Operator or Single

Operator welding mode. Place switch in W elder A/W elder B (dual oper-

ator) position for CC and CV output from Welder A (left) and Welder B (right) weld output terminals. Control the weld output from the terminals on each side using the weld controls on that same side.

Place switch in Welder B (single operator) position for CC weld output from Welder B (right) weld output terminals only. CV weld output terminals on both sides do not work when unit is in Single Operator mode.

 Welder A (left) weld output terminals are

disabled in Single Operator mode. Connect only to Welder B (right) terminals fo r Single O perator operation.

 When in single Operator mode, only CC

weld output is available. Welder A (left) and Welder B (right) side CV weld output terminals are disabled in Single Operator mode. (see Section 4-8).

2 Process Selector Switch Use switch to select output for weld process.

If switch is in Stick/Tig position, place Welder Selector switch in Welder A/Welder B or Welder B Position. If switch is in MIG position, place Welder Selector switch in Welder A/Welder B position only.

 CV weld output for MIG is only available

when W elder Selector switch is in Welder A/Welder B position. All weld output

stops if either Process Selector switch is placed in MIG position when Welder Selector switch is in Welder B position.

 Place optional Polarity switch in Reverse

position when using CV weld output. There is n o C V weld output when Polarity switch is in Straight position.

 Do not switch under load or with out-

put on.

3 Arc Force (Dig) Control Use control to automatically increase amper-

age as arc length is decreased to assist in arc starts and reduce the chance of the electrode sticking in the puddle. Turn clockwise to increase short-circuit amperage. Set at minimum for TIG welding.

4 Hot Start Switch Use switch to disable hot start circuit. Turn

switch On for Stick (SMAW) and Submerged Arc (SAW) Welding, and Air Carbon Arc Cutting and Gouging (CAC-A). T urn switch Off for TIG (GTAW) welding.

When switch is in On position, higher short-circuit amperage helps arc starting. After arc starts, the front panel or remote Amperage/ Voltage control setting determines weld amperage.

 The hot start circuit does not function

when constant voltage (CV) welding.

5 Amperage/Voltage Control When Process Selector switch is in the Stick/

TIG position, turn control clockwise to increase amperage. Read amperage from outer scale of control. The Amperage/Voltage control adjusts amperage only when constant current (CC) welding and does not adjust opencircuit voltage.

When Process Selector switch is in the MIG position, turn control clockwise to increase voltage. Voltmeter value changes as control knob is turned. Control can be adjusted while welding.

 When Welder Selector switch is in Welder

B position (single operator mode), weld amperage is two times the value selected by the Amperage/Voltage control. For example, if Amperage/Voltage control is set to 250 A, weld output is actually 500A.

6 Weld Meters With Process Selector switch in the Stick/Tig

position, meters read 0 (zero) with contacto off. Meters display actual output voltage and amperage with contactor on.

With Process Selector switch in the MIG posi tion, voltmeter displays preset voltage with contactor off. Voltmeter and ammeter displa actual output voltage and amperage with c on tactor on.

7 High Temperature Shutdown Light Light goes on and weld output stops if weld

rectifier gets too warm. Let unit cool before welding.

8 Remote Amperage/Voltage Control

Switch

For front panel control, place switch in Pane position. For remote control, place switch in Remote position, and connect remote device (see Section 4-17).

9 Output (Contactor) Switch For front panel control of output, place switch

in On (Hot) position. For remote control of out put, place switch in Remote position, and con nect remote device (see Section 4-17).

 Weld output terminals are energized

when Output (Contactor) switch is On and engine is running.

10 Polarity Switch (Optional)

 Do not switch under load.

Use switch to change polarity of weld outpu (see Sections 4-7 thru 4-14).

SECTION 9 – RUN-IN PROCEDURE

 Do not perform run-in

procedure at less than 20

volts weld output and do n ot

exceed duty cycle or equip-

ment damage may occur.

1 Welding Generator Run diesel engines near rated volt-

age and current during run-in period to properly seat piston rings and prevent wetstacking. See nameplate, rating label, or specifications section in this manual to find rated voltage and current.

 Do not idle engine longer than

necessary. Piston rings seat

faster if engine runs at weld/

power rpm, and the welding

generator is kept loaded during

run-in.

2 Engine Exhaust Pipe Wetstacking is unburned fuel and

oil in the exhaust pipe and occurs during run-in if the engine is run too long at light load or idle rpm.

If exhaust pipe is coated with a wet, black, tar-like substance, dry the engine using one of the following run-in procedures.

See the engine manual for additional engine run-in information.

consistent with regular (utility) system voltage and wiring.

Connect generator with temporary or permanent wiring suitable for the installation.

Turn off or unplug all equipment connected to generator before starting or stopping engine. When starting or stopping, the engine has low speed which causes low voltage and frequency.

5 Essential Loads Generator output may not meet the electrical

requirements of the premises. If generator does not produ c e enough output to meet all requirements, connect only essential loads (pumps, freezers, heaters, etc. – See Section 10-4).
