5-10. Preparing Unit For Synergic Pulsed MIG (GMAW And FCAW) Welding Process
Ref. 956142881_13-A
To select MIG welding process,
proceed as follows:
Prepare unit according to Section 4.
Use a cable with correct adapter,
connect gun to the MIG gun con-
nector.
For GMAW process:
Connect wire drive lead to positive
output terminal. Connect work lead
to negative output terminal. See
Section 4-5 for GMAW solid wire
with shielding gas process. See
Section 4-3 for installing gas sup-
ply.
For FCAW process:
Connect wire drive lead to negative
output terminal. Connect work
clamp lead to positive output ter-
minal. See Section 4-5 for FCAW
self-shielding wire no shielding gas
process.

Arc Length Control Knob
Use knob to select desired arc
length value. It is the distance from
end of wire electrode to the
workpiece. Rotate knob clockwise
to increase the arc length value
(min = − 40, max = +40). It allows
setting inductance in MIG mode. In
Pulse mode, this adjustment
changes the arc cone by adjusting
the preprogrammed factory pulse
data.
