Tipping
A
ARC WELDING
can cause
Electromagnel:ic
Interference.
To reduce
possible
interference,
keep
weld cables
as
short
as
possible,
close
together,
and down
low,
such
as on
the
floor. Locate
welding operation
100 meters from any sensitive electronic
equipment.
Be
sure
this
welding
machine is
installed and
grounded according
to
this manual. If interference still
occurs,
the
user
must
take
extra
measures
such
as
moving
the
welding
machine,
using
shielded
cables,
using
line
filters,
or
shielding
the work
area.
