PRODUCT DESCRIPTION
The TIG Module is an accessory for constant current
power sources. It provides high frequency and
shielding gas control for AC and DC GTAW (TIG)
welding applications, and easy connection of Amptrol
remote controls to power sources having remote
control capability. It also provides contactor control of
the welding current, always allowing the operator to
make and break the arc with an Arc Start Switch or
Amptrol remote control. A contactor option must be
used for power sources which do not have a built-in
contactor in the constant current mode.

RECOMMENDED PROCESSES AND
EQUIPMENT
EQUIPMENT
Recommended for TIG welding with AC or AC/DC
constant current welding power sources rated 250
amps or higher. This includes transformer,
transformer/rectifier and engine driven power sources
with constant current output. For a listing of machines
that the TIG Module can be used with, see Installation
Section.

control when using a remotely controllable power
source. Allows operator to adjust welding current at
the TIG module, instead of at the power source. Also
allows Hand or Foot Amptrol control range to be
narrowed, for better current control capability.

Fixed preflow timer for purging the weld area before
an arc is struck. Preflow timer is automatically
bypassed if a new weld is started during the Afterflow
time; this allows quick tacking or spot welding, without
the need to wait for the preflow time.
