rotate it until the
the long end
the short end with the lower scale.
Electrical connections between the welder and 230-volt,
single-phase, 60-Cycle a-c power source should be made by a
qualified electrician, A!l wiring must comply with the local
electrical code.
NOTE: Make sure the welder is located at least
i
12-inches from a walt. or other obstruction (at
both sides) in order to provide an unobstructed
flow of air for adequate cooling.
I. It
is recommended
that an individual
(separate)
line be
installed
for
thewelderwith
a fuse block
in the line. For
best
results,
this
circuit
should
be as short
as possible.
For
power
leads
use
armored
cable
or
non-metallic
sheathed
cable,
in accordance
with
the
local
electrical
code.
The size of the leads wilt depend
upon

serves as a pointer,
is pointed
to the

the end, wilt line up with
the upper
row of
figures
which
is labeled
the "'HI"

When
rotated
180 degrees,
the short end of the knob will line up with
