QUICK INSTALLATION PROCEDURE
For people with previous experience of the Cir-Kit Weld 450. Inexperienced people should
refer to the full instructions in the INSTALLATION PROCEDURE on page 9.
To adjust the foot cable and electrodes
Set the height adjustment on the front of the machine to 0 mm adjust the electrodes so there is
a 4 mm gap between the bottom of the electrodes and the glass table. Make sure that the
electrodes are both at the same height by bringing them down gently on to a piece of abrasive
paper and if you gently pull the paper forward, 2 equal lines should be made on the paper.
Next with the height setting still at 0 mm put a piece of paper under the electrodes and gently
push down on the foot pedal until the paper is clamped, this should be firmly clamped
without trying to weld and the adjusting screw will have stopped moving. You should still
have approximately ¼ of the downward foot pedal movement left. Now pushing a little more
on the foot pedal, the white arm below the height adjustment screw should continue to move
down giving a gap of 2-3 mm between the nut and the white arm, compressing the spring and
putting clamping pressure on the electrodes, the welder should now try and weld, beep and
show the clean light.
This 2-3 mm movement of the white arm will ensure that there is pressure on the electrodes
which is needed to give a good electrical contact to measure the current flow / resistance. If
there is insufficient pressure, the machine will not sense the correct welding times. To
increase the spring pressure wind the 2 knurled nuts upwards.
If it welds early or not at all adjust the foot pedal cable to achieve this setting.
Welding settings
The settings on the welding machine can be very difficult to control if you start changing
both amps and time settings. We have found that if you leave the time setting always at 3.40
mil seconds and always adjust the amps up or down this gives much better results.
The machine is designed to adjust the time setting for itself, therefore it will not always use
the 3.40 mil seconds set but will sense the welding resistance and cuts the time accordingly to
its threshold setting.
Only for experienced operators
If the threshold is set to 65 this will give a weak weld, 70 is normal and 75 is a very
aggressive weld. To adjust threshold setting push both amps and time button together and
adjust with + or - (on older machines, the version number of the software will display on
power up. version 5 or before the threshold setting was 120).
For normal welding the time should be 3.40, threshold 70 and only adjust the amps starting
low and working up to achieve a good weld.
