MIG WELDING WITH GAS
Check the position of the polarity cable. To weld with
gas, the gun must be set to Positive (+) polarity, and the
ground cable must be set to Negative (-) polarity. See
also REVERSE POLARITY .
Connect the MIG welding gun to the Euro receptacle
(Fig. 3, #1) located on the front panel of the machine,
and then connect the ground cable to the Dinse
receptacle (Fig. 3 , #3) also located on the front panel
of the machine. Next, connect one end of the gas hose
to the coupling on the rear panel of the machine and the
other end of the gas hose to the flow meter or regulator
connected to your gas bottle. After making all of the
lead connections, load the wire into the machine.
THE WELDING WIRE AND THE WIRE FEED
COMPONENTS ARE ELECTRICALLY CHARGED
FOR THE FIRST FOUR (4) SECONDS. KEEP HANDS
AWAY.
After waiting four (4) seconds, insert the wire into the
wire feeder; feed the wire into the groove on the bottom
drive roll.
NOTE: The drive roll has two grooves. To choose
the desired groove size, simply flip the drive roll.
When changing the size (diameter) of the wire, you
must also change the drive roll and the contact tip to
match the new wire size (diameter).
The contact tip is the little copper tip on the gun from
which the wire exits the MIG welding gun.
TIP: Remove the nozzle and the contact tip, and
also hold the gun as straight as possible, to more
easily feed the new wire through the gun lead/cable
assembly.
Insert the power plug into a suitable power receptacle,
close the pressure roller, switch the machine on by
turning the line switch to the ON position, and press the
Manual Wire Feed Button (Fig. 2, #9) to feed the wire
through the gun lead/cable assembly. Please keep the
side panel closed while manually feeding wire through
the MIG welding gun. Switch the machine off by
turning the line switch to the OFF position.
Reinstall the contact tip and the nozzle, and then adjust
the pressure of the wire feeder (for steel wire, set the
pressure to approximately 2 or 3).
Step by Step Instructions
 With the Select Mode Button (Fig. 2, #6), select
either MIG 2T or MIG 4T. In MIG 2T, depressing
the trigger makes the wire feed and also ignites an
arc when the wire makes contact with the work
surface. Releasing the trigger stops the wire from
feeding and also extinguishes the arc. In MIG 4T,
depressing the trigger starts pre-gas flow, releasing
the trigger makes the wire feed and the arc ignite
upon contact with the work surface, pressing the
trigger again stops the wire from feeding and
extinguishes the arc, and releasing the trigger again
starts post-gas flow.
 Press the Easy Set Button (Fig. 2, #7) repeatedly until all
of the Wire Selection LEDs turn off.
 Regulate the welding voltage using the V/SET Knob (Fig.
2, #12).
 Regulate the wire speed using the Wire Speed Knob (Fig.
2, #11).
 Begin welding.
MIG WELDING IN SYNERGIC MODE

Press the Easy Set Button (Fig. 2, #7) to select an
appropriate wire diameter (indicated by LEDs; Fig. 2, #1
for .035” wire, Fig. 2, #2 for .030” wire, and Fig. 2, #3
for .023”/.024”/.025” wire). If all of the LEDs are turned
off, the machine is in manual mode.
 Select the thickness of the material to be welded using the
Wire Speed Knob (Fig. 2, #11; the scale of color
corresponds to the selected wire diameter: blue for .035”
wire, yellow for .030” wire, and green
for .023”/.024”/.025” wire).
 Optional Step: With the V/SET Knob (Fig. 2, #12),
adjust the output voltage (-4V, +4V; red in scale). The
default position is 0, at the center of the scale.
MIG WELDING WITHOUT GAS
To use flux-cored wire, which allows welding without
the use of gas, proceed as follows:

Check the position of the polarity cable. To weld
with gas, the ground cable must be set to Positive
(+) polarity, and the MIG welding gun must be set
to Negative (-) polarity. See also REVERSE
POLARITY .
 Connect the MIG welding gun to the Euro
receptacle (Fig. 3, #1).
 Connect the ground cable to the Dinse receptacle
(Fig. 3, #3).
 Follow the instructions laid out in MIG WELDING
WITH GAS .
