Fitting the Gas Cylinder
Place the gas cylinder on the tray at the rear
of the welder. Retain the cylinder with the

clamp also supplied.
Remote Wirefeeder
The remote wirefeeder is connected to the
Weldmatic Fabricator power source via the
composite cable interconnecting lead. Check
all connections are firmly made to ensure good
electrical contact, and to prevent gas leaks.
Output Voltage Polarity
The design of the Weldmatic 270 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
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.
