2. Depress the operating lever fully
and insert the M6 screw provided,
into the threaded hole as shown in
Fig 5.
3. Screw in fully so that the lever is
held in the fully down position as
shown. This is the position used for
adjusting the electrode gap.
4. Before setting the electrode gap
however, it is important to ensure
that the electrode arms are parallel to each other and the electrodes are
perfectly in line, on the same axis, when the operating lever is fully
depressed. This is achieved by slackening the respective arm clamp and
rotating the arms within the receptacle until the electrodes meet exactly
and are perfectly in line. When satisfied, tighten the clamps.
5. Slacken off the upper electrode clamp and move the electrode so that a
piece of material of the same total thickness as that to be welded, can be
inserted between the electrodes, then tighten the electrode clamp. The
correct gap is now set.
6. Remove the M6 screw and release
the lever.
7. Adjust the pressure to be exerted
by the electrodes by turning the
adjuster screw (item 1, Fig.4), using
the hex. wrench provided,
(clockwise to increase,
anticlockwise to decrease)
according to the scale shown in
Fig 6.
NOTE:
Always remember that too high a pressure will result in damage to
the electrode tips, whereas too little pressure will result in a poor
weld. Pressure is also dependant upon the length of electrode
arms....the longer the arms the lighter the pressure setting. This
must be taken into account if/when replacing the electrode arms
with any of those available from you Clarke dealer, (see
Accessories).
8. Set the welding time by either turning the dial adjuster, shown in Fig 1,
(model 6T), or pressing the button shown at 1 Fig 2 (model 13T). Generally
the thicker the workpiece, the longer the welding time.
NOTE:
The time scale shown on the control panel of the 13T is a general
guide only. It is advisable to make a few test welds on material
similar to the workpiece before commencing work, making
