spark arresters when they are operated in certain loca-
tions where unarrested sparks may present a fire haz-
ard. The standard muffler included with this welder
does not qualify as a spark arrester.When required by
local regulations, a suitable spark arrester must be
installed and properly maintained. See the
Accessories section for more information.
