6 INSTALLATION
Connection to Electrical Mains
Power Supply
The Weldarc 135 & 145 is fitted with a 10 Amp
supply cable and plug.
The Weldarc 185 is fitted with a 15 Amp
supply cable and plug recognisable by a
wide earth pin. Power supply authorities
require that equipment fitted with a 15 Amp
plug shall ONLY be connected to a 240 Volt,
15 Amp power point. DO NOT modify the plug.
The minimum capacity of the main power
supply wiring and power outlet supplying
a welder is selected according to the
Effective Primary Current of the equipment.
Refer to Section 3.
The minimum recommended main power
supply circuit breaker ratings for Weldarc
inverters are listed in Section 3.
If it becomes necessary to replace the
mains flexible supply cable, use only cable
with correct current rating. See Section 3.
If it is necessary to use an extension power
supply cable, ensure that it is rated as per
Section 3. Voltage drop which will occur
over long lengths of cable will reduce the
quality of welds and the maximum welding
current available from the equipment.
As noted previously, it is not recommended
that the Weldarc inverter be powered from
small engine-driven generator sets unless
they have adequate voltage regulation. Poor
regulation results in peaks of supply voltage
which can occur with some equipment
of this type. Excessive voltage peaks
can damage the circuits of the welder.
Machines with PFC will be tolerant of poor
generator voltage regulation.
7 BASIC WELDING INFORMATION
Stick Welding (MMAW)
Connection for Stick Welding
It is important to select the electrode
polarity in accordance with the
manufacturer’s recommendations for
that electrode. Most common electrodes,
including cellulose types, are operated
with the electrode at positive polarity,
as illustrated in Figure 3.

Be certain that you are wearing suitable
protective clothing, gloves etc and that
you are working in a non-hazardous area.
If necessary, refer again to Section 1 -
Safe Practices in this manual.
Connect the work clamp to the work
piece. Place the desired electrode in the
electrode holder.
Turn on the power switch located on the
rear panel. Wait approximately 5 seconds
as the unit goes through its initiation
sequence.
