For DC Straight Polarity: The electrode cable is:
plugged into the negative DC jack and the work
cable is plugged into the positive DC jack. In this
mode the electron flowwill be from the electrode to
the work. This mode is used for hardsurfacing, mild
steel welding, cutting and burning holes.
For more detailed information regarding the current
polarity to use with specific welding rods, refer to
the table provided on the welder and to information
provided with welding rods.
Connect the work clamp to the piece to be welded,
(to complete the electrical circuit) orto the welding
table itself provided it is metallic or will conduct
electricity.

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 tess amperage.
B, Next verify the electrode diameter, by placing
the bare portion of the electrode against the
electrode diameter gauge located under the bar
chart.
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.
f
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 or aluminum and also its'
diameter (as previously determined).
Locate the electrode size and type in the
recommended amperage range table below the
welding rod gauge, and read the recommended
amperage setting, Where the electrode can be
used on either AC or DC, both recommended
settings are given,
