Note:
The unit cannot strike an arc if both the electrode holder and the work clamp are engaged in the two
negative (left and middle) ports. To work, either the electrode holder connector or the work clamp connector must
be engaged in the far right positive (+) connector with the other engaged in one of the two negative ports. Most
electrodes require reverse polarity. To maintain reverse polarity (also known as positive polarity or DCEP+) the
work clamp should be engaged in one of the two negative (
-
) ports, and the electrode holder should always be in
the positive port. When required, negative polarity may be used, and the electrode holder should then be en-
gaged in one of the two negative ports and work clamp will be moved to the positive port. Consult electrode manu-
facturer data and/or instructions for polarity recommendations and specific amp requirements. Electrode instruc-
tions are usually found attached to electrode container or box. If not, consult the electrode manufacturer
’
s online
resources and specifications for more specific information.
