The Power Feed™ 10M Dual Wire Feeder is factory set for Electrode Positive welding.

Most welding procedures use Electrode Positive weld- ing. Some Innershield procedures may use Electrode Negative welding. For most applications, the Power Feed™ 10M Dual Wire Feeder will have both sides of the Wire Drive set to the same polarity. To weld with opposite polarities, each head would have to be weld- ing on isolated work pieces and the weld cable attach- ing the two feed heads would have to be removed.

To change the DIP switch inside the Power Feed™

10M Dual Wire Feeder for electrode polarity:

1.Turn off power at the welding power source.

2.Remove the rear access panel on the wire drive.

3.Locate DIP switches on BOTH Wire Drive Boards.

4.Set DIP switch #7 on BOTH Wire Drive Boards to the desired polarity.

DIP Switch #7 Position		}
Polarity
ON (Up)	- (negative) polarity
OFF (Down)	+ (positive) polarity

5.Assemble the rear access panel to the wire drive.

6.Restore power.

VOLTAGE SENSING

The best arc performance occurs when the Power Waves® have accurate data about the arc conditions. Depending upon the process, inductance within the electrode and work lead cables can influence the volt- age apparent at the studs of the welder. Voltage sense leads improve the accuracy of the arc condi- tions and can have a dramatic effect on performance. Sense Lead Kits (K940-xx) are available for this pur- pose.

If the voltage sensing is enabled but the sense leads are missing, improperly connected, or if the electrode polarity switch is improperly configured, extremely high welding outputs may occur.

------------------------------------------------------------------------

The ELECTRODE sense lead (67) is built into the control cable, and is automatically enabled for all semi-automatic processes. The WORK sense lead

(21)connects to the Power Wave® at the four pin connector located underneath the output stud cover. By default the WORK voltage is monitored at the out- put stud in the Power Wave® 455. For more informa- tion on the WORK sense lead (21), see"Work Voltage Sensing” in the following paragraph.

Enable the voltage sense leads as follows:

TAbLE A.2

Process	Electrode Voltage	Work Voltage
	Sensing 67 lead *	Sensing 21 lead
GMAW	67 lead required	21 lead optional
GMAW-P	67 lead required	21 lead optional
FCAW	67 lead required	21 lead optional
GTAW	Voltage sense at studs	Voltage sense at studs
GMAW	Voltage sense at studs	Voltage sense at studs
