TRANSMIG VAF4HD
Manual 0-5269 3-35 INSTALLATION, OPERATION AND SETUP
3.22 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 terminal(+). If in doubt, consult the electrode wire manufacturer.
Welding current flows from the Power Source via heavy duty bayonet type 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 sta-
tionary 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
heavy duty bayonet type 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.
NOTE
For Transmig 400i or other power sources fitted with a 14 pin control socket, use interconnection
W4016000 to connect to the power source 14 pin control socket.
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 reel hub. Ensure that the wire reel hub alignment pin engages the mating
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 Torch Connection (Please refer to Subsection 3.10 & 3.13)
F Lift up the wire feeder pressure levers and pass the electrode wire through the inlet guide, between the rollers,
through the centre 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 0.9mm tip for 0.9mm wire.
H Press the INCH button to feed the wire through the gun.
