STEP 2: Mount the EWR Regulator
The EWR Regulator has the flexibility to be mounted wherever it makes the most sense for your
application. A few guidelines to consider:
■
The EWR should be mounted on a stable location away from welding sparks or places
where it can be damaged.
■
The current measuring cable, gas hoses, and power supply cable must have easy, bind-
free access to their respective connectors on the regulator.
■
Mounting location for optimum performance of EWR is between 6 to 30 feet behind the
solenoid on your wire feeder. Ideal location for robotic installations is on the pedestal at
the base of the robot. Semi-automatic and Manual applications can vary as noted. Refer
to Steps 5, 7, and 8 for additional information on hose lengths and tuning of system.

STEP 3: Shunt Installation
■
Pass either the work or electrode cable through the shunt and affix the shunt onto a stable
location.
■
Route the shunt connection cable back to the EWR. Secure the shunt connection cable
utilizing non-conductive fasteners and ties. Ensure the shunt cable is not damaged.
Do
not coil any excess cable.
■
Connect the shunt measuring cable to the EWR or EWR Pro regulator box.
Note: Do not have any part of the shunt cable in close proximity to or in contact with any
electrically charged cord, as this will give a false current signal to the regulator.
