4.15 Wire Feeder Set Up MIG (GMAW) Welding with Gas Shielded MIG Wire
Power Source Connections
A. Remove all packaging materials. Do not block the air vents at the front or rear of the Power Source.
B. Connect the work lead to the negative welding terminal (-) [positive welding te) for flux cored electrode
wire]. If in doubt, consult the electrode wire manufacturer. Welding current flows from the Power Source via dinse
terminals. It is essential, however, that the male plug is inserted and turned securely to achieve a sound electrical
connection.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in the
terminal.
!
WARNING
Before connecting the work clamp to the work piece make sure the mains power supply is switched off.
Secure the welding grade shielding gas cylinder in an upright position by chaining it to a suitable stationary
support to prevent falling or tipping.
C. Position a gas cylinder on the rear tray of the Power Source and lock securely to the Power Source cylinder bracket
with the chain provided. If this arrangement is not used or the Power Source is not fitted with a gas cylinder tray
then ensure that the gas cylinder is secured to a building pillar, wall bracket or otherwise securely fixed in an upright
position.
D. Select MIG mode with the process selection control button.
Wirefeeder Connections
A. Connect the welding power cable from the Wirefeeder's interconnection cables to the positive welding terminal (+)
[negative welding terminal (-) for flux cored electrode wire]. If in doubt, consult the electrode wire manufacturer.
Welding current flows from the Power Source via dinse terminals. It is essential, however, that the male plug is
inserted and turned securely to achieve a sound electrical connection.
B. Connect the control cable from the Wirefeeder to the 19 PIN socket on the Power Source as applicable.
C. Fit the gas regulator/ flowmeter to the gas cylinder then connect the gas hose from the rear of the Wirefeeder to
the flowmeter outlet.
D. Dual groove feed rollers are supplied as standard. Select the roller required with the chosen wire size marking
facing outwards.

E. Fit the electrode wire spool to the wire spool hub. Ensure that the wire spool hub alignment pin engages the mat-
ing hole in the wire spool. Push the retaining clip into place to retain the wire spool securely. The electrode wire
should feed from the bottom of the spool.
F. MIG Gun Connection (Please refer to Section 4.05)
G. Lift up the wire feeder pressure levers and pass the electrode wire through the inlet guide, between the rollers,
through the center guide, between the rollers, through the outlet guide and into the MIG Gun.
