Changing Electrode Polarity; Negative Electrode Polarity - Lincoln Electric POWER FEED 10M Operator's Manual

CHANGING ELECTRODE POLARITY

SETTING
The POWER FEED ® 10M Single Wire Feeder is pre-
set at the factory for Electrode Positive welding. (See
Figure A.3)
NOTE: Changing this DIP Switch does not change the
actual welding polarity. The actual welding polarity is
changed by reversing the welding cables at the power
source output studs.
This DIP Switch setting must coincide with the polarity
you are setting up to weld with for the feeder to oper-
ate correctly. Operating the POWER FEED
Single Wire Feeder with the DIP switch in the wrong
position will cause very erratic weld characteristics.

NEGATIVE ELECTRODE POLARITY

This options allows for the setting of negative polarity
sensing when a negative polarity welding process is
performed.
When negative electrode polarity is required, such as
in some Innershield applications, reverse the output
connections at the power source (electrode cable to
the negative (-) stud, and work cable to the positive
(+) stud).
When operating with electrode polarity negative the
POWER FEED ® 10M Single Wire Feeder must be set
to recognize this set-up.

To change the electrode polarity DIP Switch setting:
WARNING
• Do not touch electrically live parts or
electrodes with your skin or wet
clothing.
• Insulate yourself from the work and
ground.
• Always wear dry insulating gloves.
------------------------------------------------------------------------
1. Turn off power at the welding power source.
2. Remove the rear access panel on the wire drive.
3. Locate the DIP switches on the Wire Drive Board.
4. Set DIP switch #7 to the desired polarity.
5. Reinstall the rear access panel and restore power.
