2-6. Typical MIG Process Connections Using A Constant Speed Wire Feeder
Y Weld current can damage
electronic parts in vehicles.
Disconnect both battery
cables before welding on a
vehicle. Place work clamp as
close to the weld as possible.
Constant speed wire feeders are
used with constant voltage (CV)
power sources having a 14-pin re-
ceptacle.
. For flux cored welding
(FCAW), contact welding wire
manufacture for polarity rec-
ommendations.

2-7. Typical MIG Process Connections Using A Voltage-Sensing Wire Feeder
Y Weld current can damage
electronic parts in vehicles.
Disconnect both battery
cables before welding on a
vehicle. Place work clamp as
close to the weld as possible.
Voltage sensing wire feeders are
used with constant current (CC) or
constant voltage (CV) power
sources (14 pin receptacle not re-
quired).
If using a CC welding power source
without a weld output contactor, use
optional secondary contactor.
For GMAW, use optional gas valve.
