4.16 Wire Feeder Set Up MIG (GMAW) Welding with Gasless 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 positive welding te). 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. 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 negative welding terminal
(-). 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. Dual groove feed rollers are supplied as standard. Select the roller required with the chosen wire size marking
facing outwards.

D. 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.
E. MIG Gun Connection (Please refer to Section 4.05)
F. 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.
!
WARNING
DO NOT WEAR GLOVES WHILE THREADING THE WIRE OR CHANGING THE WIRE SPOOL.
G. Lower the pressure levers and with the gun lead reasonably straight, feed the electrode wire through the gun. Fit
the appropriate contact tip, eg a .035" tip for .035" wire.
H. Press the INCH button to feed the wire through the gun.
