IMPORTANT: The AMPERAGE ADJUSTMENT con-
trol may be adjusted while welding.
A. Without Electroslope
When not using an Electroslope and the AMPERAGE
switch on the TIG-Unit is in the PANEL position, the AM-
PERAGE ADJUSTMENT control on the TIG-Unit al-
ways functions as a fine amperage adjustment (cali-
brated in percent) of the AMPERAGE ADJUSTMENT
control on the welding power source. If a remote control
is used and the AMPERAGE switch on the TIG-Unit is in
the REMOTE 14 position, the remote control always
functions as a fine amperage adjustment (in percent) of
the AMPERAGE ADJUSTMENT control on the welding
power source.
B. With Electroslope
IMPORTANT: For the TIG-Unit to function properly, en-
sure the the AMPERAGE control switch on the welding
power source is always in the REMOTE 14 position. The
position of the OUTPUT (CONTACTOR) control switch
on the welding power source is determined by the situa-
tion. If Remote Contactor Control is desired, place the
switch in the REMOTE 14 position. If Remote Contactor
Control is not desired, place the switch in the ON posi-
tion.
When using an Electroslope, the AMPERAGE switch
on the TIG-Unit must be in the PANEL position and then
the AMPERAGE ADJUSTMENT control on the TIG-
Unit has complete control of the current of the welding
power source.
