3.17 Setup for SPOOL GUN MIG (GMAW) Welding with Gas Shielded Mig Wire
A. Select MIG mode with the process selection control (refer to Section 3.06.13 for further information).
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 heavy duty bayonet type terminals.
It is essential, however, that the male plug is inserted and turned securely to achieve a sound electrical
connection.
C. Fit the Euro Spool Gun to the power source using the front panel EURO torch adaptor (refer also to section
3.07 Attaching the Tweco Fusion Mig Torch). Connect the 8 pin Remote Control Plug to the 8 pin Remote
Control Socket on the power source.
D. 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 heavy duty bayonet type terminals. It
is essential, however, that the male plug is inserted and turned securely to achieve a sound electrical
connection.
E. Fit the welding grade shielding gas regulator/flowmeter to the shielding gas cylinder (refer to Section 3.14)
then connect the shielding gas hose from the rear of the power source to the regulator/flowmeter outlet.
F. Refer to the Weld Guide located on the inside of the wirefeed compartment door for further information.
G. Select MIG mode with the process selection control (refer to section 3.06.13 for further information).
H. Set the Spool Gun Switch located inside the wire drive compartment, to SPOOL GUN.
!
WARNING
Before connecting the work clamp to the work make sure the main 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.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused
in the terminal.
Remove any packing material prior to use. Do not block the air vents at the front or rear of the
Welding Power Source.
