WELDING OPERATION
Once the installation of the equipment is completed, connect the work Cable to the
negative output terminal and the cable end of the electrode holder to the Positive output
terminal. These cable connections should be tightened properly to avoid electrical heating
due to loose connections. Put the Main Switch box in 'ON' position and turn on power
ON/OFF switch. The green lamp on the panel of the Power Source will now glow and the
fan will start rotating. Now the equipment is ready. Connect an Electrode with the
Electrode Holder. The welding current can be controlled by the current control
potentiometer mounted on the front panel of the Power Source or through Remote
Controller as explained below.
a) WELDING CURRENT ADJUSTMENT
Put the local/remote switch to 'Local' mode. Now set the DC output current as required
with the help of the current control potentiometer and ignite an experimental Arc. For the
fine tuning of the required current, set the parameters using the Ammeter mounted on the
front panel of the power source.
b) LOAD VOLTAGE/OPEN CIRCUIT VOLTAGE
Press and set Amps/Volts switch to volts position, the meter on the front panel will now
indicate the output DC voltage. On releasing this switch, it will automatically come back to
Amps position and the meter will read the output DC Welding current.
c) REMOTE CONTROLLER
The output Welding current can be increased and decreased as desired from the
operation point with the help of the Remote Controller unit as per the following guideline,
even on load condition.
Set the Local/Remote switch to remote position and connect the remote controller to the
socket provided in the power source. Now set the Welding current by turning current
control potentiometer. Graduation of the current value mentioned on the Remote
Controller Unit should be followed as guideline. However, for accurate output current,
adjust the potentiometer to a proper value from the METER mounted on the Front panel
of the power source after generating as experimental arc.
