current welding or all-position welding, selecting the correct arc force current is even more important.
Set it according to the requirement of the welding process.

4.2.5 Arc ignition current potentiometer

It is used to adjust the arc ignition current value, and it does not function in TIG mode. Generally, it is
recommended to set the arc ignition current at a higher value. It can be adjusted to a lower value to
reduce spatter during arc ignition or to avoid workpiece burn-through when the workpiece is very thin.

4.2.6 Interface for the remote control

When using the remote control with cable wire, insert the aviation plug on the remote control cable into
the interface for the remote control on the power source, and tighten it clockwise. Turn the local
control/remote control switch on the front panel of the power source to “remote control” position, to set
the power source to remote control state. At this time, the current control knob on the front panel of the
power source will not function, and the welding current can only be adjusted through the current
control knob on the remote control. Connect the remote control to the corresponding interface when
using remote control, and then the welding current can be adjusted by the remote control.

4.2.7 MMA/TIG switch

Turn the MMA/TIG switch to “MMA” position, to use MMA welding function. Turn the MMA/TIG switch
to “TIG” position, to use the TIG welding function.

NOTE!

Lift-arc is adopted in TIG mode.

1. Lean the ceramic nozzle of the TIG torch to the work piece.

2. Lower the electrode gradually to contact the work piece by shaking the torch.

3. Move the electrode away from the work piece gently by shaking the torch
again.

4.2.8 LED indicator

When the overcurrent indicator illuminates, it indicates that the power source fails or an accidental halt
occurs. In this condition, shut down the power source and restart it. If the problem persists, shut down
the power source and contact the service personnel. When the overheating indicator illuminates, the
power source will stop welding. In this condition, it is unnecessary to shut down the power source, and
welding can be continued after the overheating indicator goes out. The thermostat is used to protect
the power source from overheating, to prolong the lifespan of the power source. Overheating might be
caused by many factors, for example the fan does not work normally, the power source has been used
for a long time beyond the rated duty cycle, or the power source has worked for a long time in the
environment with a high temperature (over 40 °C). Once overheating occurs, the thermostat will turn
off the current and voltage output of the power source.

4.3 Welding operation

MMA welding process

Switch on the air switch on the back panel after correctly installing the power source, and the power
source will be started. Then, the current meter on the front panel displays the preset current value,
and the fan begins to work, then, adjust the welding current and adjust the arc force current.

4.4 Precautions

Overcurrent/overvoltage/overheating protection circuit is installed in this power source. When the
mains voltage, output current or inner temperature exceeds the set standard, the power source will
stop automatically. Too high voltage or other excessive use might cause damage. Pay attention to the
following precautions.

Good ventilation

This power source can create powerful welding current and has strict cooling requirements that cannot
be met with natural ventilation. Therefore the built-in fan is very important for effective cooling and
stable operation. The operator should make sure that the louvers be uncovered and unblocked. The
minimum distance between the power source and nearby objects should be 30cm.

Overvoltage is forbidden

This power source has automatic mains voltage compensation, which ensures that the welding current
varies within a given range. In case that the input mains voltage exceeds the tolerance value, it might
damage the power source. The operator should understand this circumstance fully and adopt relevant
precautions.

4   OPERATION

Overload is forbidden

Remember to observe the max load current at any moment (refer to the corresponding duty cycle).
Make sure that the welding current should not exceed the maximum load current. Overload might
shorten the power source's lifespan, or even damage the power source.

A sudden stop occurs with the yellow indicator on the front panel illuminating while the power source is
in overload state. Under this circumstance, it is unnecessary to restart the power source. Keep the fan
working to lower the temperature inside the power source. Welding can be continued after the inner
temperature falls into the standard range and the yellow indicator goes out.

4.5 Work after welding

1) Turn off the power of the power source 3–5 mins after the welding work is finished.

2) When shutting off the power, turn off the air switch on the power source firstly and then switch off
the power in the switching box.

power source (for example that the unit is not being overloaded)

Check that the welding power source is not clogged with dirt.

connected.

Check that the correct current value is set.

Check that the correct electrodes are being used.

6.2 Troubleshooting

Type of fault Cause and solution

The fan does not work and
the meter does not display
after the power source is
started.

1. Make sure that the power switch is closed.

2. Make sure that the input voltage is normal.

3. Check that the fuse on the back panel is blown.

The fan works, the meter
displays normally, but there
is no welding output.

1. The overheating indicator illuminates:

• The power source is under overheating protection.
In this condition, it is unnecessary to pull out the
power plug, and it will recover automatically after
the power source is cooled down.

• Check that the thermal switch is damaged, and
replace it if necessary.

2. The overcurrent indicator illuminates:

• The power source is under overcurrent protection.
In this condition, shut down the power source, and
power it on again to carry out welding.

• If the overcurrent indicator still illuminates after the
power source is powered on again, it indicates that
the power device may be damaged. If this occurs,
contact our service center.

The rated current of the electrode holder is smaller than its actual
working current. Replace with a higher rated current.

1. The output polarity connection is incorrect. Reverse the
polarity.

2. The arc force current is too high. Adjust the arc force
current appropriately.
