We feel that welding with your new Craftsman dual range
arc welder is as simple as A B C
A Determine
what diameter electrode should
be used by
gauging the piece to be welded on the material thickness
gauge The fractional
number directly
beneath the bar
chart dictates what the proper electrode diameter is for
given thicknesses of metals You will note that a specific
diameter
of
electrodes
can
be used
on
varying
thicknesses
of
material.
This
is accomplished
by
adjusting the heat selector for more or less amperage•
B Next verify
the electrode diameter, by placing the bare
portion
of the electrode
into
the electrode
diameter
gauge on the right side of the cabinet
Because electrodes
are mass produced,
there may be
small burrs on the bare ends of the electrode
Make sure
the
bare end of the rod
is as clean as possible for
accurate sizing,
C, Finally,
determine
the
type
of
electrode
by
the
identification
on the
package or
by
the
American
Welding Society number stencilled on the coated portion
of the electrode,
bearing in mind the type of electrode
you have chosen -
E6013
or E7014,
and also its'
diameter (as previously determined)_
Locate that band on the amp scale There are two E6013
bands and two
E7014
bands,
use the
band which
coordinates
with the amp range you have selected•
Now loosen the heat selector knob and move the pointer
until
the fractional
number
matching
your
electrode
diameter appears in the pointer window
Tighten the heat selector knob
Insert
the
electrode
cable
into
the
proper
jack
(depending
on the range selected), Connect the work
clamp to the work.
Wear Welding Helmet,
Turn the On-Off switch to the "ON"
position
and you
are ready to weld
Because metals vary in their make up and the technique
of each operator is different,
you may find it necessary
to increase or decrease the amperage output accordingly,
CAUTION:
Do not loosen and move heat selector while
welding
The duty
cycle ratings bracketing
the amperage scales are
provided for your convenience and protection
of your new
welder_ Duty cycle is the performance
level of the welder
based on a 10 minute time span. For example welding for 6
minutes out of 10 minutes is a 60% duty cycle
To avoid
possible
overheating
of the welding
transformer,
which
could shorten the life of your welder, Do Not exceed the
duty cycles listed on the nameplate
