5 INSTALLATION
Connection to Electrical Mains
Power Supply
The Weldmatic Fabricator is supplied with
a 5 metre 4 core 50/0.25 Heavy Duty PVC
mains power supply cable. This cable
should be correctly connected to a suitable
3 Phase plug top or fixed connection point.
The minimum capacity of the mains wiring
and power outlet supplying a welder is
selected according to the effective primary
current of the machine. The effective
primary current for a Weldmatic Fabricator
is 18 Amps.
The minimum recommended mains circuit
breaker rating for a Weldmatic Fabricator is
25 Amps.
Note: Due to normal variations of
sensitivity, the tripping time of some 25A
circuit breakers may limit the duty cycle
available from the Weldmatic Fabricator.
A higher rated circuit breaker can be
selected, but the mains wiring capacity
must be increased to suit.
The current rating of the mains cable
depends on cable size and method of
installation. Refer to AS/NZS 3008.1,
Table 9.
If it becomes necessary to replace the
mains flexible supply cable, use only cable
with correct current rating. Access to the
supply terminals is gained by removing the
power source side panels.
The replacement cable must be fitted
and retained in the same manner as the
original.
Output Voltage Polarity
The design of the Weldmatic Fabricator
allows selection of the output voltage
polarity.
Positive Wire
G.M.A.W. with solid consumable wires is
carried out with the work piece Negative
and the welding wire Positive.
To setup for this condition, connect the
‘WORK’ lead plug into the (-) output socket
on the Power Source, and the ‘WELDING’
lead from the wirefeeder into the (+) socket
on the Power Source, as in Figure 2.
NOTE. All electrical work shall
only be undertaken by a qualified
electrician.
