Weld current can damage elec-
tronic parts in vehicles. Discon-
nect 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
required).
If using a CC or CV welding power source
without a weld output contactor, use optional
secondary contactor.
�
For GMAW, use optional gas valve.
