IMPORTANT NOTE:
Refer to RECOMMENDED SETTINGS on page 23 of this manual for the
recommended settings for specific track widths. However, as copper composition
varies considerably, these are only guidelines. Adjustments will inevitably have to be
made for fine-tuning.

To store in memory depress Store Button (S) followed by either, adjust b or -,
until a vacant memory channel is selected. Depress (S) again. The Time, Amps and
Work lamp intensity has now been stored in that channel. The display will return to
either Time or Amps.
The above procedure can be repeated up to 99 times.
9
To recall any memory channel, depress Recall (R), followed by adjust b or -
until the channel number is displayed Depress (R) again and the Amps or Time
allocated to that channel will be displayed. The
CIR-KIT WELD 450
will operate at
that energy level and work lamp intensity.
10
To operate in a manual mode, use the Time, Amps and Work lamp intensity with the
adjust b or -, but do not press the Store (S) button.

Clean the PC Track with the Glass Fibre Cleaning Pencil supplied. Remove dust, etc.
Select a repair ribbon from the spools supplied, ie the nearest in width to the PC track
that you intend to repair.

With the damaged track positioned under the Electrodes, but slightly to the left,
slowly depress the Foot Pedal Switch and by viewing through the Microscope, lower
the Electrodes onto the track. Once the Electrodes are in contact with the track, final
adjustment of the PCB to the Electrodes can be made.
IMPORTANT NOTE:
Once contact between the Electrodes and the PC track has been made, do not continue
to exert pressure on the Foot Pedal Switch as the weld circuitry will automatically be
fired, which may damage the track further.

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 it senses the welding resistance and cuts the
time accordingly to its threshold setting. (see threshold settings at end of this section
only for experienced operators)
