Negative Electrode Polarity | Lincoln Electric IM915 specification

CHANGING ELECTRODE POLARITY SETTING

The Power Feed™ 10M Single Wire Feeder is preset 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™ 10M 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.

(See Figure A.3)

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.

DIP Switch #7 Position	Polarity
ON	(negative) - polarity

OFF	(positive) + polarity
