SETTING ELECTRODE POLARITY
ELECTRIC SHOCK can kill.
• Turn the input power OFF at the dis-
connect switch before working on
this equipment.
• Do not touch electrically hot parts.
• Only qualified personnel should install, use or
service this equipment.
When changing the electrode polarity, the weld
cables must be changed at the power source
studs and the DIP switches inside the eCell™ Wire
Drive System must be properly set. Operation
with the DIP switch in the wrong position will
cause erratic arc performance.
------------------------------------------------------------------------
The eCell™ Wire Drive is factory set for Electrode
Positive welding.
Most GMAW welding procedures use Electrode
Positive welding. Some Innershield procedures may
use Electrode Negative welding.
To change the DIP switch inside the eCell™ Wire
Drive for electrode polarity: (See Figure A.5)
1. Turn off power at the welding power source.
2. Remove the sheet metal wrap-around on the wire
drive.
3. Locate DIP switches on the Wire Drive Board.
4. Set DIP switch #7 to the desired polarity.
DIP Switch #7 Position Polarity
ON - (negative) polarity
OFF + (positive) polarity
5. Assemble the wrap-around to the wire drive.
6. Restore power.
