INSTRUCTION
Read and understand the entire manual regarding the rules for users’
safety before installing, operating, or servicing the equipment.
A procedure, when not properly followed, may cause injury to the
operator or others in the operating area.
Equipment Identification
Receipt of Equipment
The identification number (specification or part number), model, and serial
number of this unit usually appear on a nameplate attached to the control
panel; record these numbers for future reference.
When you receive the equipment, check it against the shipping documents.
Make sure it is complete and inspect the equipment for possible damage
during shipping. If there is any damage, notify the carrier immediately to file a
claim.
Move the equipment to the installation site before uncrating the unit. Use care
to avoid damaging the equipment when using bars, hammers, etc. to uncrate
the unit.
Falling machine due to lifting device failure may cause death or injury.
﹡Lifting device may fail when overloaded.
﹡Avoid sudden jerks, drops or swinging.
﹡Check lifting device components visually for loose spot and signs of metal fatigue.
﹡Before changing any hardware, check grade and size of bolts, and replace with bolts of equal or higher
size and grade.

Protection
Operation and maintenance involve potential hazards. All operators and
personnel should be alerted to possible hazards and precautions should
be taken to prevent possible injury.
Electrical
Maintenance
Personal
Machine：
﹡The system’s non-fuse breaker is compatible with its maximum power and main
voltage.
﹡The connection, single-phase or three-phase, is possible on a stand compatible with
the plug of its cable link.
﹡To prevent accidental electrical shock, do not leave the ground cable disconnected
when the system’s power is connected to local power network.
Work place：
﹡Be very careful to avoid contact between metal part of phase conductor and the
neutral of electric network.
﹡Electrical messes of different electrical machine and apparatus are connected
between themselves and with the terminal of earth neutral wire.
Interventions：
﹡Before control and repair, see that the apparatus is switch off and electrically
insulated.
﹡Connection with fixed installation cable is impossible.
﹡Switch off by fixed connection is multi-polar (phase and neutral).
﹡It’s on “STOP” and connection is impossible.
Some apparatus are provided with starting circuit HT HF (with a plate). Never enter
into the corresponding switch cupboard.
﹡Only qualified persons are authorized for intervention concerning electrical
installation.
*Check regularly the equipment’s power cords, switch, extension cords’s electrical
insulation and connection and make sure they are in good state
*Maintenance and repairing of cable insulation are important to prevent injury.
*Do request trained personnel for system repair and replacement of defective
accessories.
*Check regularly all electrical connections for any sign of overheating.
﹡Avoid touching metal area with bear hands..
﹡Wear safety clothes, gloves, apron, safety shoes and glasses for protection against
welding burns, welding radiation and slag.

2.9 WELDING CURRENT SETTING
100% amperage value setting (analog output 1).
A1 Initial current (A) Initial current level after arc ON signal is received.
A2 Peak current (A) Main welding current. If pulse wave function is enabled, this
value is the peak current value.
A3 Valley(low) current(A) If pulse wave function is enabled, this value is the low current
value. Can’t set more than A2.
A4 Welding crater current(%) Welding ending current.
T1 Initial current time(sec) 0~10 sec, initial arc stabilize time after arc ON signal is received.
T2 Rise current time(sec) 0~10 sec, rise time from initial current A1 to peak current A2
T3 Peak current time(sec) 0.01~10 sec, peak current duration before change to valley
current.
T4 Valley current time(sec) 0.01~10 sec, valley current duration before change to peak
current.
T5 Current fall time(sec) 0~10 sec, amount of time current drop from A2 to A4. The count
starts after welder output is switched off. \
T6 Welding crater time(sec) 0~10 sec, amount of time for crater current.
CH2 Analog voltage(%) Channel 2 analog voltage 0~100% = 0~10VDC.
Note 1: If both T3 & T4 are set to 0, the wave pulse function is disabled.
Caution: Even though pulse wave function’s output voltage can reach a frequency of 50Hz, the
welder may not be able to change current at this rate.
