.

2  HIGH FREQUENCY SWITCH - Used to select

Continuous High Frequency, Start Only High
Frequency, or High Frequency Off.

3  AFTERFLOW  CONTROL - Adjust the afterflow

time from 5 to 55 seconds. This is the time the
shielding gas (and, if equipped, cooling water) flows
after the weld is completed.  This extra gas flow
cools the TIG torch and  the tungsten electrode.

4  CURRENT CONTROL - This control functions only

when the TIG module is used with a power source
having remote control capability.  It controls the
welding current, and is used in conjunction with the
Local/Remote Switch.

5  LOCAL/REMOTE  SWITCH - This switch functions

only when the TIG module is used with a power
source having remote control capability.  When in
the Local position, all output current control is done
by the Current Control on the TIG Module.  When in
the Remote position, the Current Control on the
TIG Module sets the maximum available welding
current, and an Amptrol, plugged into the Amptrol
Receptacle, can adjust the welding current.  See
the Chart labeled
