SAFETY PRECAUTIONS
When using a DC-400 power source with wire feeders
which do not have an electrical trigger interlock (or
with wire feeders with the electrical trigger interlock in
the OFF position), there will be a small spark if the
electrode contacts the work or ground within several
seconds after releasing the trigger.
When used with some wire feeders with the electrical
trigger interlock in the ON position, the arc can restart
if the electrode touches the work or ground during
these several seconds.
• Be sure to select OUTPUT TERMINALS “REMOTE
ON/OFF” for operation with wire feeders that have
leads numbered 2 and 4.
ELECTRIC SHOCK
can kill.
• Have an electrician install and ser-
vice this equipment.
• Turn the input power off at the fuse
box before working on equipment.
• Do not touch electrically hot parts.
