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.
