5.10 Setup for MIG (GMAW) Welding with Gasless Mig Wire
A. Fit the MIG Torch to the Power Source. (Refer to Section 5.02 Attaching the Tweco Fusion MIG Torch).
B. Connect the Mig Torch polarity 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.
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 ot 4T mode. Refer to Section 4.02.12.
D. Select MIG mode with the process selection control (refer to Section 4.02.13 for further information).
E. Fit the correct V Knurled Feed Roll for the Gasless 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 Sections 5.03 for 300mm diameter spools or 5.04
for 200mm diameter spools.
G. Feed wire through the wire drive mechanism. Refer to Section 5.05.
H. 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 Dinse terminals. It is essential, however,
that the male plug is inserted and turned securely to achieve a sound electrical connection.
I. 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.
WARNING
Before connecting the work clamp to the work make sure the mains power supply is switched off.
!
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in the terminal.
Remove any packaging material prior to use. Do not block the air vents at the front or rear of the Welding Power Source.
