Optional Low Open Circuit Voltage (OCV) Welding Modes

Low OCV Operation
The unit can be optionally configured for low open circuit voltage (OCV) operation in OUTPUT ON: Wire, Stick, Lift-Arc TIG modes. When
the unit is configured for low OCV operation a lower sensing voltage is present between the electrode and the workpiece prior to the elec-
trode touching the workpiece. Consult a Factory Authorized Service Agent for information regarding how to configure the unit for low OCV
welding operation.

Alternate Configuration Functions

There are 2 ways that the remote control can be configured to operate on this machine. The configuration of the meters can be changed by
placing the process selection switch into either Stick or Gouge modes and turning the output on and off 3-5 times within a few seconds, this
can be done by triggering a feeder or by activating the output on-off switch on a remote control. The feeder or remote control must be con-
nected to the remote 14 receptacle. The amperage window will briefly display what mode is selected before returning to a preset display.
C 1
Configuration 1 is the factory default setting. Stick or Gouge modes
recognize a remote plugged into the remote 14 receptacle, the am-
perage window will display the percentage of preset being set from
the remote, the panel will set the maximum amperage. An ArcReach
device will have full range control and override a remote connected to
the remote 14 receptacle.
In either Stick or Gouge modes Configuration 2 changes the opera-
tion of any remote control connected to the remote 14 receptacle.
When Configuration 2 is selected either Stick or Gouge modes oper-
ate in Panel Only control. Any remote control connected to the remote
14 receptacle will be ignored and have no effect on the output. When
either Stick or Gouge modes are active, a decimal point will be dis-
played in the amperage window. Configuration 2 has no affect on the
operation of an ArcReach device.
