HOT INCH

Hot inch occurs when the trigger is pulled and an arc is
not established. After a 1.5 second period, the
Sequencer will jump to the Weld state and the wire
feeder will run at the preset wire feed speed on the dis-
play. The wire is hot (output is on) at this point. Start,
Upslope, Downslope, Crater, Burnback, Postflow, etc
are all skipped when Hot Inch is activated.

FOOT AMPTROL

A Foot Amptrol Kit can be installed in order to operate
the output of the machine using a pedal. Located on
the Control Box, the Right encoder turns output on/off
if desired. The left encoder sets the max work point
limit. When the pedal is pressed OCV will be present
and gas will not flow. As soon as the tungsten touches
the work and there is current flow, the gas solenoid will
turn on. If the arc breaks the machine will enter the
postflow state. When the postflow timer expires, the
machine will return to OCV mode and no gas will flow
until the arc is established. If the pedal is released it
turns the machine off, postflow will be entered until
time out. When the postflow timer expires the machine
will return to idle state and wait for trigger. Preflow will
be presettable for external triggers if desired.
Triggering machine with encoder will skip preflow.
WIRE DRIVE -- PC BOARD ADJUSTMENTS
ELECTRODE POLARITY:
The system needs to be aware of the electrode polari-
ty. A DIP switch setting on the Wire Drive PC boards is
used for this purpose. See INSTALLATION Section
"Setting DIP Switches in the Wire Drive".
GEAR BOX RATIO:
The systems needs to know which gear has been
installed on the Wire Drive, low or high speed. A DIP
switch setting on the Wire Drive PC boards is used for
this purpose. See INSTALLATION section"Wire Drive
Ratio" for information on how to set the DIP Switch.
