Supply
Negative Wire
Some ‘self-shielded’ flux cored consumable
wires are operated with the work piece Positive
and the consumable wire Negative. Refer
to the manufacturers data for the particular
consumable wire to be used.
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 3.

NOTE. All electrical work shall only be
undertaken by a qualified electrician.
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 21 Amps.
The minimum recommended mains circuit
breaker rating for a Weldmatic Fabricator is 20
Amps.
Note : Due to normal variations of sensitivity,
the tripping time of some 20A 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.
Fitting Eye Bolts
Remove 12mm transport bolts and replace with
supplied eye bolts and fibre washers.
Centralise the internal nut as the eye bolt is
tightened. Use a bar through the centre of the
eye bolts to tighten firmly.
