INSTALLATION
DC-400
A-8
To change stick polarity, reverse the leads at the (+)
and (-) terminals on the right side of the Multiprocess
Switch.
NOTE: When a DC-400 equipped with Multiprocess
Switch is mounted on an undercarriage, the
undercarriage handle in the resting position
can hit the case of the Multiprocess Switch.
This does no harm, but if the user desires, a
1/4” or 3/8” bolt and nut may be placed in the
hole in the undercarriage tow bar to limit the
travel of the undercarriage handle.
STICK, TIG OR AIR/CARBON ARC *
a) Turn off all power.
b) Disconnect all wire feed unit control, electrode, and
work leads.
c) Place MODE SWITCH in the “CONSTANT CUR-
RENT (STICK/TIG)” for air carbon arc.
d) For stick, TIG or air carbon arc, place OUTPUT
TERMINALS switch into the “ON” position. With
the DC-400 connected for stick, TIG or air carbon
arc welding, the output terminals will be energized
at all times.
*NOTE: If stick welding, TIG welding or air carbon arc
cutting is to be done on the DC-400 along
with semi-automatic/automatic welding, then
a K804-1 Multiprocess Switch is required. If
the Multiprocess Switch is not used, then all
control, electrode, and work leads to wire
feed equipment must
be disconnected from
the DC-400 before connecting the DC-400 for
stick or air carbon arc cutting.
