Operating Instructions
Description
Ensure the unit is situated in a location so the supervisor or welding co-ordinator can operate
the switch easily.
It is important that the welding cables coming from the welding power source are connected
to the Isolation Switch so that the '+' and '-' terminals match.
If you are using a power source fitted with a polarity switch, still make sure the welding cables
match like-for-like and set the switch on the power-source to negative (-Ve).
NOTE 1:
The panel, (top left side) indicates by use of the symbols 'A' and 'B' which polarity may be selected.
The desired polarity will depend on whether the welding stinger cable or the return (earth)
cable is connected to either 'A' or 'B' terminals.
The terminal connections fitted to each Firefly unit are standard DIN (35-50mm2) plugs/socket
(see duty cycle table for ratings).
Ensure you only use approved standard DIN cable connections.
Ensure you connect cables from the welding power-source to the correct side on the Firefly unit.
These should be connected to the panel plug side, as marked on the panel – TO WELDING PLANT.
Ensure you connect like-for-like, matching the polarity symbols to the welding power-source.
Once the cables from the welding power-source are connected, turn on the machine and check to
see that the volt meter registers (no need to connect the welding cables to the diver yet).
The volt meter is a zero centred meter and so the needle should rise in an upwards direction.
If the meter falls (drops) in a downward direction, then the cables are not matched like-for-like!
(Check connections and/or polarity switch and re-test).
NOTE 2:
When using the on/off knob, do not use excessive force, particularly when making COLD, as the
switch will operate with the minimum of resistance.
Connect the cables to the power-source and ensure the machine is 'on'.
Test whether the indicator light operates correctly, pull the red on/off knob to make a live (HOT)
connection; the indicator lamp will now illuminate.
By pushing the red on/off knob down (making is COLD) the indicator light will extinguish.
This procedure now ensures the correct set-up and you are ready to connect the welding cables
to the diver.
Should the lamp fail to illuminate, then the bulb may have blown. (Please return your unit for inspection).
