SELECTING DC RANGES
Your new arc welder has a DC range which makes it
possible for youto weld aluminum using al uminum
welding rods. You will find this increasing_.y useful
as aluminum is be ngused eXtensively today,
mostly because o_ its light weight,: corrosion
resistance, and its ability to conduct heat.
The DC range is also preferred for verticat and
overhead welding, for welding thin metals, for
reducing pop-outs; with many difficult to use rods,
suitable for electrodes up to 3/!6 inch diameter.
Either range may be used, depending on operator
preferences when the electrode diameter permits.

CONNECTING ELECTRODE AND WORK
CABLES FORAC WELDING
Insert the tapered plug on the: end of the electrode
cable into theproper Outlet jack depending on
range required, insert the tapered plug on the end of
the:work cable into_the AC work jack.
:To insure a good electrical connection always twist
the: electrode plug _slightty: while inserting. To
rem0ve the plug twist in theopposite directi on while
remowng:
NOTE:: If_you extend the welding:iilCables:beyond
those already supplied, they:must be No: 4 AWG or
larger to avoid an undue drop:in:weiding:currenL
DO NOT EXTEND CABLES OVER 50 FEET.
Connect the work c amp to the: piece to be welded,
(to complete the etectdcai circuit) or to the weiding
table itself provided it is metailic orwill conductl
electricity!
CONNECTING ELECTRODE AND WORK
CABLES FOR DC WELDING
Polarity: In DC welding it is possible to change the
direction of electron flow. This is done by changing
the manner in which the electrode cable and the
workcable are plugged into the DC jacks.
ForDC Reverse Polarity: The electrode cable is
plugged into the positive DC jack and the work
cable is plugged into the negative DC jack._ In this
mode the electron flow wilt be from the wo_rk to the
electrode. This mode may be used for ahJminum
welding, weldi ng .on thi n sheet metal, cast iron a nd
high carbon steel. This is also the best mode for
overhead and vertical welding.
