3.1.1.1
Use of the engine generator and auxiliary power
• To prevent the welding power source from being damaged or arc loss, follow the
instructions below.
When using an engine generator for the welding power source, pay attention to the following.
•
Set the output voltage of the engine generator to the voltage range between 400 and 460 V at no-load
welding operation.
Setting to an extremely high output voltage may result in damage to the welding power source.
3-1
CHAPTER
3
TRANSPORTATION AND INSTALLATION
REQUIRED EQUIPMENT
•
Use an engine generator with a damper winding that has a capacity of more than twice the rated input
(kVA) of the welding power source.
Generally, the recovery time of the engine generator's voltage for load change is slower than that of the
commercial power source. If the engine generator does not have sufficient capacity, sudden current
change such as arc start will occur and this may result in an abnormal decrease in output current or arc
loss.
•
Be sure to use a single welding power source with a single engine generator. If more than two welding
power sources are combined, output voltage will become unstable with a likely result of arc loss.
Use the auxiliary power of engine welder with an improved voltage waveform.
Some engine welders have poor electricity that may cause product damage on the welding power source.
3.1.2
Ventilation equipment/partial exhaust facility
This section explains the ventilation equipment and partial exhaust facility in welding work area.
3.1.2.1
Ventilation equipment

places of poor ventilation, ensure to provide ventilation equipment.
Condition of ventilation equipment:
Oxygen concentration of 18 % or more must be maintained in the welding work area.
• Gas of larger gravity than that of oxygen, such as carbon dioxide gas or argon gas,
retains at the bottom part.
To prevent anoxia due to the retention gas, provide ventilation equipment.
• When it is difficult to provide ventilation equipment or the ventilation equipment does
not give sufficient performance, ensure to use respiratory protective equipment.
• Periodically inspect the ventilation equipment to ensure correct and proper
performance of ventilation.
3.1.2.2
Partial exhaust facility
To prevent any health damage due to poisonous gas or particle substances (fume) emitted in the welding
operation, provide partial exhaust facility.
• When it is difficult to provide a partial exhaust facility or the ventilation or exhaust
facility does not give sufficient performance, ensure to use the respiratory protective
equipment.

• If the welding power source which is not grounded is used, voltage will be generated in
the case through the capacitor between the welding power source input circuit and the
case or floating capacity (electrostatic capacity naturally generated between the input
conductor and the case metal). If you touch the case, you may suffer from electric
shock. Be sure to ground the case of the welding power source.
• Be sure to connect the input cable (3 pcs) in the correct position and securely tighten
them to the terminal block.
Improper connection may cause electric shock, fire and damage to the welding power
source.

4.6 Wiring of Voltage Detection Cable at Base Metal Side
When the extension cable is 30 m or more in length in total, use of the voltage detection cable at the base
metal side is recommended.
The voltage detection cable needs to be wired so that the correct feedback of the arc voltage can be
obtained. Connect the voltage detection cable as near as possible to the base metal to avoid detection of
voltage decrease.
Use the voltage detection cable at base metal (optionally available: K5416N00 or K5416G00) by
connecting with the wire feeder or to the voltage direct detection terminal at the base metal side on the
front of welding power source.
When using the voltage detection cable, set the internal function F38 to "ON". ( 6.7.1 Setting

This chapter explains the procedures from preparation to completion of the welding operation.
5.1 Precaution at Welding Operation
This section explains the safety precautions for welding operation.
5.1.1
Precautions for air discharge and use of respiratory protective
equipment
To prevent suffocation or gas poisoning in the welding operation, ensure to follow the instructions
below:
• When welding is required in tank, boiler, reaction tower, or hold of a ship, closed space,
or any other places of poor ventilation, ensure to provide ventilation equipment.
• Gas of larger gravity than that of oxygen, such as carbon dioxide gas or argon gas,
retains at the bottom part.
To prevent anoxia due to the retention gas, provide ventilation equipment.
• When it is difficult to provide ventilation equipment or the ventilation equipment does
not give sufficient performance, ensure to use respiratory protective equipment.
• For preventive measure from falling due to anoxia, apply lifelines such as a safety belt.
• For the welding operation in a narrow space, perform the operation with the trained
supervisor.
• Periodically inspect the ventilation equipment to ensure correct and proper
performance of ventilation.
To prevent any health damage due to poisonous gas or particle substances (fume) emitted in the welding
operation, ensure to follow the precautions below:
Chapter 5
Welding Operation
• To reduce the dust concentration, install a partial exhaust facility such as fume suction
device, or install the collective ventilation equipment.
• When it is difficult to provide a partial exhaust facility or the ventilation or exhaust
facility does not give sufficient performance, ensure to use the respiratory protective
equipment.
• In performing welding or cutting the coating steel plate or galvanized steel sheet,
provide a partial exhaust facility or let the welding operator as well as the surrounding
operators use respiratory protective equipment. (Welding or cutting the coating steel
plate or galvanized steel sheet will cause toxic gas or fume.)
• Do not perform welding operation in the vicinity of degreasing, cleansing, or spraying
operation. Performing the welding operation in such places may generate poisonous
gas.

Precaution for protective equipment
For protection from arc ray generated from welding, spatter and spattering dross and hearing disorder
from noise, observe the following:
• Wear safety goggles with sufficient blocking effect or face shield in the work area and
the surrounding.
Ignoring the above may cause inflammation and burn from arc ray.
• Wear safety goggles in the work area and the surrounding.
Ignoring the above may cause injury in the eye or burn from spatter and spattering
dross.
• Wear protective equipment such as protective leather gloves, long-sleeve clothes, leg
covers, and leather apron.
Ignoring the above may cause electrical shock and burn.
• Install protective screens or barriers to protect the eyes of others in the work area from
arc ray.
• Wear an ear protector when noise level is high.
Ignoring the above may cause hearing disorder.
5.1.3
Precautions on welding place
To avoid poor welding, ensure to follow the instructions below:
• When the welding is performed outside with wind or when wind is caused by the indoor
ventilation facility (including fan), provide a partition to avoid the arc generating part
being exposed to wind.
5.2 Check before Welding
This section explains the check parameters before welding. To avoid welding problems beforehand,
check the parameters below when the welding environments are prepared. (These are the check
parameters recommended by OTC. They also contain check parameters after power ON or after shield
gas supply.)

6.5 Memory Function of Welding Conditions
This section explains the memory function of welding conditions.
The welding power source is equipped with the function to register the welding conditions and reads
them out for use. The number of welding conditions that are able to be registered are 100 at maximum.
Single welding condition can contain the following information at registration:
•
Welding mode selected by the keys on operation panel (Shield gas/Wire/Crater/Penetration control, etc.)
•
Welding current/voltage for each welding sequence (
•
Part of internal function (

This section explains the adjustment procedure of arc characteristics (arc status). Using this function
enables to adjust the arc status into soft or hard condition.
Press the ARC CONTROL key. When the LED of the key is ON, it means the arc control is ON.
The setting value is displayed on the right digital meter, and can be adjusted by the parameter
adjustment knob. (Positive value: soft arc condition, negative value: hard arc condition)
TIPS
• It is likely that good weld can be obtained by adjusting it to "hard" in low current region and
"soft" in high current region.
• When using an extended cable for the base material side /torch side or using an extended
torch cable, it is likely that good welding can be performed by adjusting it to "hard."
6.6.7
Penetration control adjustment
This section explains how to adjust the penetration control. Using the constant penetration function
enables to automatically adjust the wire feed speed so that the constant welding current can be assured
even when the wire feeding length changes.
Press the CONSTANT PENETRATION key. When the LED of the key is ON, it means the penetration
control is ON.
This results in reduction of changes in penetration depth and bead width of the base material. Especially
for welding where you desire to make penetration depth constant, use the welding power source with
this penetration control function enabled.
TIPS
• The penetration control functions only during the production weld while it does not during
the initial and crater processes. Also, the function cannot be used in arc spot.

6.7.2.13 F16: Slowdown speed adjustment
Slow-down speed is the speed to slowly feed the wire from the time of the machine start to the time of
arc start.
The slowdown speed is automatically set to an appropriate speed depending on the welding method and
wire diameter; meanwhile, it can be adjusted through this function if manual setting is preferred.
The setting range is ±1.0 m/min, yet cannot be adjusted slower than 0.4 m/min. Based on "0," adjusting
it to the negative direction lowers the speed, and adjusting it to the positive direction accelerates the
speed.
When the starting performance is poor, decrease the slow-down speed to a negative value (which lowers
the wire feed speed).
When the starting performance is not poor, setting the slow-down speed to a positive value (which
accelerates the wire feed speed) can shorten the tact time.
6.7.2.14 F17/F18: Anti-stick time/voltage adjustment
Set the anti-stick time/voltage, which is the anti-stick processing time and voltage. Optimum setting of
the anti-stick time/voltage enables to obtain the following effects:
•
At the welding completion, wire adhesion to the base material can be prevented.
•
The shape of wire tip can be arranged to obtain a stable start of the next welding.
The time and voltage for anti-stick process are automatically set to appropriate conditions depending on
the welding method (wire type) and wire diameter; meanwhile, it can be adjusted through this function
if wire should cause adhesion at the end of welding or if burning is too intense.
•
Adjust the anti-stick process time in the range of ±50 (unit: 0.01 seconds) through the internal function F17.
Based on "0," adjusting it to the negative direction shortens the time, and adjusting it to the positive
extends the time.
•
Adjust the anti-stick process voltage in the range of ± 9.9 V through the internal function F18. Based on
"0," adjusting it to the negative values decreases the voltage, and adjusting it to the positive increases the
voltage.

Wire consumption
Wire consumption is controlled according to the setting range.
•
P20 (Cumulative wire consumption used in welding)
Wire consumption (kg) used in welding is measured and counted.
The setting range of count value is between 0 and 999 kg. The count value will be cleared according to the
"P22" setting.
(If continuous operation is enabled, the value will be cleared when exceeding 999 and returns to 0.)
TIPS
• Approximate wire consumption will be obtained with the wire consumption control
function.
The table below shows the wire unit amount (g/m3) calculated from the specific gravity
(g/cm3) of the wire material. Wire consumption is calculated based on the unit amount
and the wire feeding amount during welding. Therefore, there will be differences
between the actual consumption and the calculated value depending on the wire
constituents.
• When wire consumption is 100 kg or lower, the value after the decimal point is also
displayed.
• The wire consumption used in inching or wire slowdown is not measured.

Simplified data log function
The welding status can be checked on a computer by sampling the data during welding and backing
them up in the USB memory. Only three of the following data can be sampled.
• Welding current set value
• Welding voltage set value
• Wire feeding speed set value
• Welding current actual value • Welding voltage actual value • Wire feeding speed actual value
The data types/sampling speed should be specified in the internal function F52/F53 (data log function).
( 6.7 Setting Internal Functions)
Simplified data log will be created below the "DAIHEN_OTC_Welbee\DAT\DAT00001" folder. A csv
file will be created per welding.
When DAIHEN_OTC_Welbee\DAT\DAT00001 folder is already existing, "DAT00002" folder will be
created below the "DAIHEN_OTC_Welbee\DAT" folder and folder for the consecutive number will per
created for each simplified data log.

8.1 Precautions for Maintenance and Inspection
Chapter 8
Maintenance and Inspection
This section explains the precautions for maintenance and inspection work.
To prevent electric shock or burn injury, ensure to follow the instructions below:
• Do not touch the input and output terminals and the internal live electrical parts of the
welding power source.
• Perform periodical maintenance and repair damaged parts if any before use.
• Maintenance, inspection and repair should be performed by qualified persons or
persons familiar with the Welding power source.
• Before starting maintenance and inspection, make sure to cut the input power with the
disconnect switch in the box connected with the welding power source and wait three
minutes or more.
The capacitors may be still charged even after the input power is cut. Make sure that
there is no charged voltage before starting the work.
• During maintenance and inspection, take an appropriate measure to prevent turning on
the input power.
Special attention is necessary because the welding power source contains many parts
connected to the input side due to its high-frequency inverter method.
• Periodically blow the parts of welding power source with dry compressed air to remove
dust.
Powder dust accumulating inside may cause insulation deterioration, resulting in
electric shock or fire.
• Before maintenance and inspection, wait until the temperature inside the welding
power source becomes low.
The main circuit parts such as DC reactor and heat sink are hot just after welding.
Touching them accidentally may cause burn injury.
To prevent being caught/pinched by the rotating parts, ensure to follow the instructions below:
• Removing the cases for maintenance, inspection or repair should be performed by
qualified persons or persons familiar with the Welding power source. Also put up a
barrier around the Welding power source or take other necessary measure to prevent
other people from getting in the nearby area.
• Keep your hands, fingers, hairs and clothes away from the rotating cooling fan and the
open parts around the cooling fan;

MAINTENANCE AND INSPECTION
PRECAUTIONS FOR MAINTENANCE AND INSPECTION
To prevent damage and problem of the welding power source and loss of the data, ensure to follow the
instructions below:
• The welding conditions (electronic data) stored by this function are susceptible to
occurrence of static electricity, impact, repair, etc., and there is a possibility that the
stored contents may be changed or lost. Important information should also be stored
as printed document.
Please note that OTC will not be liable for any alteration or loss of electronic
information.
• When cleaning the welding power source, do not expose the cooling fan directly to
compressed air.
Otherwise powder dust may get inside the cooling fan. Also the cooling fan may rotate
at high speed due to compressed air, resulting in wearing of the bearing.
• When using a vacuum cleaner to remove powder dust accumulating on the welding
power source, do not vacuum between the rotating part of cooling fan and the main
body.
Otherwise lubricant of the bearing of cooling fan may also be removed, resulting in
failure or shorter service life of the cooling fan.

• Check that there is no deterioration, damage or other abnormality in
consumable parts of the welding torch. Abnormality in consumable parts can
prevent smooth wire introduction.
• Blow with dry compressed air from the front slit (ventilation hole) to the back side
to remove dust inside the welding power source.
Dust accumulating on the heat sink of transistor and rectifier may prevent heat
radiation, adversely affecting the transistor. Also, accumulation of dusts
between the winding of transducer could deteriorate insulation.
Cleaning inside the welding power
source
Compressed air
• Dust accumulating on the fin or winding of heat sink can cause insufficient heat
radiation.
Remove the left side panel and fan frame and check the the dirt inside. If there
is heavy dirt, blow the fin and coils of heat sink directly with compressed air to
remove dust inside.

8.4 Periodical Replacement Parts
This section explains the parts to be replaced periodically.
•
Printed circuit board PCB7 ( 10.1 Parts List)
The printed circuit board PCB7 inside the welding power source has a high voltage electrolysis capacitor.
The high voltage electrolysis capacitor supplies stable direct current to the inverter circuit, but its
performance will degrade year by year.
-
For replacement of the printed circuit board PCB7, contact your dealer.
• Even if the part is replaced by the user, please contact your dealer.
• When inserting the connector to the printed circuit board, check that the number
printed on the printed circuit board is the same as the number indicated on the
connector, and insert firmly to the end.
• Do not turn on the power switch of welding power source when the connector of printed
circuit board is disconnected.
•
Others
Fan, relay, and rated power supply has a certain lifetime; they are recommended to be replaced once in
approximately five years.
When replacement of fan, relay, and rated power supply is necessary, please contact your dealer.
8.5 Insulation Resistance Measurement and Withstand
Voltage Test
If insulation resistance measurement and withstand voltage test is necessary, please contact your dealer.
• The customer MUST NOT perform the withstand voltage test. If withstand voltage test
is necessary, ensure to contact your dealer.
• Insulation resistance measurement should be conducted by qualified persons or
persons familiar with the welding machine. Also, fence and other neccessary measures
should be taken around the welding machine to prevent other people from getting in
the nearby area.
• Conducting insulation resistance measurement by customer may result in injury or
equipment failure. For insulation resistance measurement, be sure to ask your dealer.
•
When measuring insulation resistance and testing withstand voltage, follow the steps below.
Refer to the schematic diagram, parts layout, and parts list for maintenance.
‒
Disconnect the input power cable and grounding cable from the disconnect switch and short-circuit
the input terminal.
8-5
Chapter 8
Maintenance and Inspection
If the printed circuit board PCB7 is used for an extended period without being replaced, it may result in
performance degradation of the welding power source and damage of the high voltage electrolysis
capacitor or other parts.
It is recommended to replace the printed circuit board PCB7 every five years.
CHAPTER
8
MAINTENANCE AND INSPECTION
INSULATION RESISTANCE MEASUREMENT AND WITHSTAND VOLTAGE TEST
‒
Short-circuit the positive (+) and the negative ( - ) sides of the output terminal.
‒
Unground all the case grounding cables (line No.80, total of 6 positions) and insulate them with
insulation tape.
‒
For DR1, 2 and 4, short-circuit the AC side and positive (+) output side and the AC side and negative
( - ) output side respectively.
‒
Short-circuit between TR1 (C1) and (E1C2), TR1 (E1C2) and (E2), TR3 (C2) and (E2).
‒
Apply NF.
‒
After finishing insulation resistance measurement, return the above to the original state.
• After finishing insulation resistance measurement, it is necessary to remove the
shortcircuit cables and return the welding power source to the original state.
If the power is turned on without returning it to the original state, the welding power
source will burn out.

Chapter 9 Troubleshooting
This chapter explains the typical troubleshooting for the welding power source.
The cause of problems can be categorized as below:
•
Mechanical problems (e.g., problems of driving mechanism of the wire feeder)
•
Electric and control problems
•
Operational errors
A problem may become complicated as a result of mix of multiple causes. If a problem has occurred in
the welding power source, it is necessary to identify its cause and address it appropriately.
For question concerning problems, contact your dealer.
9.1 Action in Case of Error
•
The "WARNING" LED and the "Temperature WARNING" LED light/flash
