5 INSTALLATION
Connection to Electrical Mains
Power Supply
The Weldmatic 356 is supplied with a 5
metre 4 core 47/0.20 Heavy Duty PVC
mains power supply cable. The Weldmatic
396 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 Weldmatic 356 and
Weldmatic 396 are 15 Amps.
The minimum recommended mains circuit
breaker rating for a Weldmatic 356 is 20
Amps and Weldmatic 396 is 25 Amps.
Note: Due to normal variations of
sensitivity, the tripping time of some circuit
breakers may limit the duty cycle available
from the Weldmatic 356 & 396 machines.
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.
Fig 2 Positive Wire
Output Voltage Polarity
The design of the Weldmatic 356 & 396
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.
