4. Switch ON using the switch
located on the rear panel.
• The display on the front panel
will come on and show the
current setting in amps.
•
If the machine stops at any time
and the thermal overload
indicator comes ON, the thermal
overload device has intervened.
Wait until the welder has cooled
sufficiently (the thermal overload indicator goes out) before restarting
work.
5. Set the required current using the
current selector.
• With practice you will gain a
feel for the correct current
setting for different welding rod
thicknesses.
VRD-VOLTAGE REDUCTION DEVICE
The VRD is a safety feature that It is also known as “Anti-shock”.
Its function is to lower the open circuit voltage across the output terminals to a
safe 12V when the welder is not in use.
As soon as the welder is used (a load
of 200 ohms or less is detected), the
voltage will increase to the full output
to enable welding to commence.
The “VRD” will only turn the output of
the welder back to a reduced output
state of 12 volts once the electrode Is
removed from the work piece or If
the resistance across the output rises
above 200 ohms.
If you wish to turn off this feature, set the VRD switch on the front panel to OFF.
We recommend that you leave it switched ON.
