4-2. Mode And Voltage Control
1 Remote 14 Receptacle
Mode Control
The unit defaults to standard MIG
mode.
Pulsed MIG welding requires that
an external pulsing control be con-
nected to the Remote 14 recep-
tacle. The remote pendant controls
whether the unit is in standard MIG
or pulsed MIG mode. When the
pulsing control is disconnected, t he
unit returns to standard MIG opera-
tion.
Voltage Control
The unit defaults to Panel control of
output voltage. When a suitable re-
mote voltage control or pulsing con-
trol is attached to the Remote 14 re -
ceptacle, the remote device as-
sumes control of output voltage.
To return to Panel control of voltage,
disconnect or disable any remote
devices that send an input to pin E.
