The following sizes of rods can be used and are available from your CLARKE dealer.

5. Attach the earth clamp to the workpiece as close as possible to the area being

welded. Clean the workpiece with a wire brush where necessary to ensure the

connection is as clean as possible.

PREPARING THE WORKPIECE

The area being welded should be perfectly clean. Any coating, plating or corrosion

must be removed, otherwise a good weld will be impossible to achieve.

CONTROL SETTINGS

Refer to page 12 for control panel functions.

1. Set the Welding Current Selector knob (4) according to the size of the weld being

performed.

2. Confirm the electrode and cables are configured as shown on page 15.

3. Aim at the welding line and scratch the work piece to start the arc. The “working”

indicator will be on.

With practice you will gain a feel for the correct current setting for different welding

rod thicknesses.

THERMAL OVERLOAD

The ‘Thermal Overload’ shuts off the welder when it becomes too hot, due to the duty

cycle being exceeded. This is to prevent any damage to the machine.

When this occurs, the warning lamp will light up. Allow the welder to cool until the

amber light extinguishes before resuming work.
