SYNERGY UW CUTTING /WELDING SAFETY ISOLATION SWITCH # SY-BRUW-CWS
Now you are ready to connect the welding cables to the
diver side on the Firefly unit. You will note that on this side
of the panel as well as the usual +/- polarity symbols, you
will also see instructions on how to change polarity. All
polarity changes
MUST ONLY
be made from the diver side
of the panel. To deliver positive (+Ve) polarity to the stinger
(electrode holder) connect the stinger cable to the terminal
marked [A]. To deliver negative (-Ve) polarity to the stinger
cable, connect the stinger cable to the terminal marked [B].
DO NOT ALTER THE CABLES FROM THE WELDING MACHINE
SIDE OF THE PANEL, OR CHANGE THE CABLES ON THE
WELDING MACHINE.
The Synergy Safety isolation switch is fitted with an approved 400-amp, dual pole switch; the duty
cycle of which is as shown on the data label, affixed to the panel (see copy below). As the switch is
fitted in an enclosed space, the duty cycles are adhered too, otherwise serious overheating may
occur. If you notice the unit getting hot during operational use, then allow an extended cooling
period to take place.
It is important to ensure you use the correct sire of welding cable for the selected current.
However, please note voltage drop may also need to be taken into account, as the size and length
of the welding cable used may also need to be considered. Typical current ratings data for use with
copper welding cables manufactured in accordance with BSEN 50525-2-81:2011 are shown below.
