6. Set the Balance control to the position which best suits your "AC-Tig"
welding condition — Remember that when using "Maximum Penetra
-
tion" mode, your duty cycle (AC welding arc time) must be reduced
(see Fig. 1-3 or 1-4 - Duty Cycle chart). Also remember that for DC
welding applications, this control should always be set for "Maximum
Cleaning".
7. Adjust the Current Control potentiometer for the approximate welding
current desired. Remember, that the setting placed on this potenti-
ometer will be the maximum current which can be regulated from a
Remote Foot or Torch Control.
8. Depending on the type of current regulation desired, place the "PANEL-
REMOTE" Current Control switch (SW5) as follows:
PANEL Position -- permits full range current regulation only from the
power source’s Current Control potentiometer.
REMOTE Position -- permits current regulation from a remote location
by connecting either the Foot or Torch control options to the Remote
Control receptacle (J2). Note that welding current regulation from
the remote control option is "always" limited to the maximum cur-
rent that you preset on the power source main Current Control
dial. For example: if the main Current Control dial is set at 50, the
remote control will provide full range, finer tuned current values up to
the equivalent setting of 50 on the main Current Control dial; however,
if you want complete remote current control operation, the main Cur-
rent Control dial on the power source must be set at the maximum.
ELECTRIC SHOCK CAN KILL! Do not use
AC output in damp areas, if movement is
confined, or if danger of falling exists.
Use AC output only if required for the
welding process.
Do not change the position of this switch
while welding.
