5.14 Setup for Manual MIG (GMAW) Welding with Gas Shielded MIG Wire
A. Fit the MIG Torch to the Power Source. (Refer to Section 5.06 the Tweco Professional Fusion MIG Torch).
B. Connect the Mig Torch polarity lead to the positive 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.
C. Switch the Power Source On/Off switch located on the rear of the Power Source to the On position and
ensure the Power indicator on the Front Panel is illuminated. Set the MIG Torch trigger switch operation
either 2T or 4T mode. Refer to Section 4.02.15.
D. Select MIG mode with the process selection control (refer to Section 4.02.12 for further information).
E. Fit the correct Feed Roll for the Gas Shielded MIG wire being used. Refer to Section 2.11 Options and
Accessories for Feed Roll types and Part Numbers
F. Place the MIG wire spool onto the spool holder. Refer to Section 5.07 for 300mm diameter spools or 5.08
for 200mm diameter spools.
G. Feed wire through the wire drive mechanism. Refer to Section 5.09.
H. Connect the work lead 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.
I. Set Internal Switch in the wirefeeder compartment to <1> Local / 4RX / Spool Gun position. Refer to Section
4.02.26.
J. As a guide for the welding parameter settings for the welding job refer to the Weld Guide located on the
inside of the wirefeed compartment door. Power Source settings are adjusted using the front panel controls.
Refer to Section 4.02.
